Intravenous injection of bortezomib, melphalan and dexamethasone in refractory and relapsed multiple myeloma.

BACKGROUND: A combination of bortezomib (1.3 mg/m(2)), melphalan (5 mg/m(2)), and dexamethasone (40 mg) (BMD), with all three drugs given as a contemporary intravenous administration, was retrospectively evaluated. PATIENTS AND METHODS: Fifty previously treated (median 2 previous lines) patients with myeloma (33 relapsed and 17 refractory) were assessed. The first 19 patients were treated with a twice-a-week (days 1, 4, 8, 11, 'base' schedule) administration while, in the remaining 31 patients, the three drugs were administered once a week (days 1, 8, 15, 22, 'weekly' schedule). RESULTS: Side-effects were predictable and manageable, with prominent haematological toxicity, and a better toxic profile in 'weekly' schedule (36% versus 66% in 'base' schedule). The overall response rate was 62%. After median follow-up of 24.5 months (range 2.7-50 months), the median progression-free survival (PFS) was 21.6 with no difference between the two schedules and the median overall survival (OS) was 33.8 months. Independently from the adopted schedule, we found that also in a cohort of relapsed/refractory patients achieving at least partial remission improved PFS (35.2 versus 9 months) and OS (unreached median versus 18 months). CONCLUSION: Taken together, our observations suggest that BMD is an effective regimen in advanced myeloma patients with acceptable toxicity.

Assessment of activity of Crohn's disease of the ileum and large bowel: proposal for a new multiparameter MR enterography score.

PURPOSE: We evaluated the diagnostic accuracy of magnetic resonance enterography (MR-E) in assessing Crohn's disease (CD) activity by differentiating acute, chronic and remission stages of disease through a quantitative MR-E assessment. MATERIALS AND METHODS: One hundred patients with a histological diagnosis of CD were studied with MR-E. Intestinal distension was obtained by oral administration of approximately 2 L of a polyethylene glycol solution (PEG). In all cases, the ileum and large bowel were imaged with morphological sequences (heavily T2-weighted single-shot, dual fast-field echo, balanced fast-field echo) and a postcontrast dynamic sequence (T1-weighted high-resolution isotropic volume excitation). Disease activity was assessed according to a multiparameter score (0-8) based on lesion morphology, signal intensity and contrast enhancement. MR-E findings were compared with clinical-laboratory data and disease activity indices [Crohn's Disease Activity Index (CDAI); Inflammatory Bowel Disease Questionnaire (IBDQ)]. Multiple regression analysis was performed by correlating MR-E score, CDAI and IBDQ. Frequencies were then compared using the χ (2) test. RESULTS: MR-E identified inactive disease in 9% of cases, chronic disease in 57% and active disease in the remaining 34%. The most frequently involved bowel segment was the terminal ileum (52%). A statistically significant correlation was found between MR-E score and CDAI (R=0.86; p<0.001) and between MR-E score and IBDQ (R=-0.83; p<0.001). The most suggestive parameter for disease activity was layered bowel-wall enhancement, a finding predominantly present in patients with increased CDAI (≥ 150) and/or local complications (χ (2)=7.13; p<0.01). CONCLUSIONS: MR-E is a noninvasive and diagnostic imaging modality for CD study and follow-up. The MR-E score proposed in this study proved to be useful in assessing disease severity and monitoring response to treatment.

Lidocaine 700 mg medicated plaster for post-herpetic neuralgia: focus on Quality of Life, effectiveness and safety - a retrospective observational study.

OBJECTIVE: Postherpetic neuralgia (PHN) is a neuropathic pain syndrome following herpes zoster (HZ) infection, characterized by pain that persists for months to years after the resolution of the HZ rash. Therapeutic management remains challenging for every clinician. We report the follow-up of patients diagnosed with PHN and treated with lidocaine 700 mg medicated plaster (LMP), focusing on effectiveness, safety, and Quality of Life (QoL). MATERIALS AND METHODS: This study is a retrospective observational investigation of patients with PHN treated with LMP. Patients were regularly followed for pain intensity, co-analgesic consumption, adverse effects, QoL using the EQ-5D, and patient satisfaction for 8 weeks. RESULTS: A total of 31 patients were evaluated. At enrollment, 18 patients (58.1%) were treated with at least one PHN concomitant medication, for which the number and dosing remained constant during the study. Patients had a mean average pain intensity of 6.5±1.0 at baseline, which decreased to 3.6±1.1 at week 4 and 2.8±0.9 at week 8. Four patients reported erythema, and one complained of vesicles eruption associated with pruritus. EQ-5D at weeks 4 and 8 of treatment showed persisting improvements in all domains except for the "anxiety/depression" domain. At week 8, <80% of patients reported to be satisfied or very satisfied. CONCLUSIONS: This study adds further weight to the growing body of clinical and research evidence that LMP treatment is effective and well-tolerated in patients with PHN.

Septic shock due to Escherichia coli meningoencephalitis treated with immunoglobulin-M-enriched immunoglobulin preparation as adjuvant therapy: a case report.

BACKGROUND: Gram-negative bacteria are an uncommon etiology of spontaneous community-acquired adult meningitis and meningoencephalitis. Escherichia coli is a Gram-negative bacterium that is normally present in the intestinal microbial pool. Some Escherichia coli strains can cause diseases in humans and animals, with both intestinal and extraintestinal manifestations (extraintestinal pathogenic Escherichia coli) such as urinary tract infections, bacteremia with sepsis, and, more rarely, meningitis. Meningitis continues to be an important cause of mortality throughout the world, despite progress in antimicrobial chemotherapy and supportive therapy. The mortality rate fluctuates between 15% and 40%, and about 50% of the survivors report neurological sequelae. The majority of Escherichia coli meningitis cases develop as a result of hematogenous spread, with higher degrees of bacteremia also being related to worse prognosis. Cases presenting with impaired consciousness (that is, coma) are also reported to have poorer outcomes. CASE PRESENTATION: We describe the case of a 48-year-old caucasian woman with meningoencephalitis, with a marked alteration of consciousness on admission, and septic shock secondary to pyelonephritis caused by Escherichia coli, treated with targeted antimicrobial therapy and immunoglobulin-M-enriched immunoglobulin (Pentaglobin) preparation as adjuvant therapy. CONCLUSION: Despite the dramatic presentation of the patient on admission, the conflicting data on the use of immunoglobulins in septic shock, and the lack of evidence regarding their use in adult Escherichia coli meningoencephalitis, we obtained a remarkable improvement of her clinical condition, accompanied by partial resolution of her neurological deficits.

Videofluorography swallow study of patients with systemic sclerosis.

PURPOSE: This study was undertaken to evaluate the role of the videofluorographic (VFG) swallow study in patients with systemic sclerosis. MATERIALS AND METHODS: Over a 23-month period, 45 women (mean age 58 years, range 27-76 years) with a known diagnosis of systemic sclerosis and a history of dysphagia underwent a dynamic and morphological study of the oral, pharyngeal and oesophageal phases of swallowing with videofluorography. All examinations were performed with a remote-controlled digital C-arm device with 16-in image intensifier, 0.6- to 1.2-mm focal spot range and maximum tube voltage of 150 kVp in fluorography and 120 kVp in fluoroscopy. Cineradiographic sequences were acquired for the swallow study with 12 images per second and matrix 512 x 512 after the ingestion of boluses of high-density (250% weight/volume) barium. The evaluation of oesophageal peristalsis was documented with digital cineradiographic sequences with six images per second in the upright and supine positions during the swallowing of barium (60% weight/volume), and the water siphon test was performed with the patient in the supine position to evaluate the presence of gastro-oesophageal reflux disease (GORD). All patients subsequently underwent laryngoscopy, endoscopy and pH monitoring, and the data thus obtained were processed and compared. RESULTS: The VFG swallow study identified alterations of epiglottal tilting associated with intraswallowing laryngeal penetration in 26 patients (57.8%), pooling of contrast agent in the valleculae and pyriform sinuses in 23 (51.1%) and radiographic signs of nonspecific hypertrophy of the lingual and/or palatine tonsils in 18 (40%). The study of the oesophageal phase revealed the presence of altered peristalsis in all patients, and in particular, 36 patients (80%) showed signs of atony. Altered oesophageal clearing mechanisms were evident in all 45 patients, sliding hiatus hernia in 43 (93%) and GORD in 44 (97%). CONCLUSIONS: Our study demonstrated that in patients with systemic sclerosis, there is no primary alteration of the oral or pharyngeal phase of swallowing. In addition, alterations of epiglottal tilting associated with laryngeal penetration of contrast agent were found to be secondary to chronic GORD. Indeed, in 40% of patients, radiographic signs were found that indicated nonspecific hypertrophy of the lingual tonsil and/or palatine tonsils and nonspecific signs of chronic pharyngeal inflammation, and GORD was identified in 93% of patients, which in 40% of cases extended to the proximal third of the oesophagus. The data obtained were confirmed in 85% of cases with pH monitoring and in all cases with laryngoscopy.

Long head of the biceps tendon and rotator interval.

The term "biceps brachii" is a Latin phrase meaning "two-headed (muscle) of the arm." As its name suggests, this muscle has two separate origins. The short head of biceps is extraarticular in location, originates from the coracoid process of the scapula, having a common tendon with the coracobrachialis muscle. The long head of biceps tendon (LBT) has a much more complex course, having an intracapsular and an extracapsular portion. The LBT originates from the supraglenoid tubercle, and in part, from the glenoid labrum; the main labral attachments vary arising from the posterior, the anterior of both aspects of the superior labrum (Bletran et al. in Top Magn Reson Imaging 14:35-49, 2003; Vangsness et al. in J Bone Joint Surg Br 76:951-954, 1994). Before entering the bicipital groove (extracapsular portion), the LBT passes across the "rotator cuff interval" (intracapsular portion). Lesions of the pulley system, the LBT, and the supraspinatus tendon, as well as the subscapularis, are commonly associated (Valadie et al. in J Should Elbow Surg 9:36-46, 2000). The pulley lesion can be caused by trauma or degenerative changes (LeHuec et al. in J Should Elbow Surg 5:41-46, 1996). MR arthrography appears to be a promising imaging modality for evaluation of the biceps pulley, through the distention of the capsule of the rotator interval space and depiction of the associated ligaments.

Femoroacetabular impingement: role of imaging.

The femoroacetabular impingement (FAI) is an impingement characterized by repetitive abutment between the femur and the acetabular rim during hip motion due to loss of joint clearance (Imam and Khanduja in Int Orthop 35(10):1427-1435, 2011; James et al. in AJR Am J Roentgenol 187(6):1412-1419, 2006). Femoroacetabular impingement (FAI) can be classified as either cam or pincer type, and it can be differentiated on the basis of a predominance of either a femoral or an acetabular abnormality (Pfirrmann et al. in Radiology 244(2):626, 2007; Ganz et al. in Clin Orthop Relat Res 466(2):264-272, 2008). In cases of cam FAI, the nonspherical shape of the femoral head at the femoral head-neck junction and reduced depth of the femoral waist lead to abutment of the femoral head-neck junction against the acetabular rim. In cases of pincer FAI, acetabular overcoverage limits the range of motion and leads to a conflict between the acetabulum and the femur. The most important role of preoperative MR evaluation in patients affected by FAI is the accurate assessment of the damage's extension.

Mechanism of traumatic knee injuries and MRI findings.

Bone bruises are focal abnormalities in subchondral bone marrow due to trabecular microfractures as a result of traumatic force. These trauma-induced lesions are better detected with magnetic resonance (MR) imaging using water-sensitive sequences. Moreover, the pattern of bone bruise is distinctive and allows us to understand the dynamics of trauma and to predict associated soft injuries. This article discusses the mechanism of traumatic injury and MR findings.

Diagnostic imaging of ankle impingement syndromes in athletes.

The chronic ankle pain is a very frequent clinical problem, which is often characterized by a painful mechanical limitation of full-range ankle movement. A large amount of causes are involved in its pathogenesis, but the most common forms are secondary to an osseous or soft tissue abnormality. Especially for professional athletes, impingement lesions are the most important causes of chronic pain; however, this symptomatology can also affect ordinary people, mostly in those who work in environments that cause severe mechanical stress on the joints. This group of pathologies is characterized by a joint conflict secondary to an abnormal contact among bone surfaces or between bones and soft tissues. Diagnosis is mainly clinic and secondly supported by imaging in order to localize the critical area of impingement and determine the organic cause responsible for the joint conflict. Treatments for different forms of impingement are similar. Usually, the first step is a conservative approach (rest, physiotherapy, ankle bracing, shoe modification and local injection of corticosteroids), and only in case of unsuccessful response, the second step is the operative treatment with open and arthroscopic techniques. The aim of the study is to describe different MR imaging patterns, comparing our data with those reported in the literature, in order to identify the best accurate diagnostic protocol.

Ankle fracture: radiographic approach according to the Lauge-Hansen classification.

Ankle fractures account for 9 % of fractures (Clare in Foot Ankle Clin 13(4):593-610, 1) representing a significant portion of the trauma workload; proximal femoral fractures are the only lower limb fracture to present more frequently. Ankle fractures have a bimodal age distribution with peaks in younger males and older females (Arimoto and Forrester in AJR Am J Roentgenol 135(5):1057-1063, 2). There has been threefold increase in the incidence among elderly females over the past three decades (Haraguchi and Armiger in J Bone Joint Surg Am 91(4):821-829, 3). In 1950, Lauge-Hansen devised a classification of ankle fractures based on the position of the foot and the deforming force at the time of injury. This has been widely accepted by orthopedists, but is not in general use by radiologists. Identification of the fractures and classification of the type of injury allows diagnosis of the otherwise occult ligamentous injuries. Three radiographic views of the ankle (anteroposterior, mortise, and lateral) are necessary to classify an injury with the Lauge-Hansen system. Two additional criteria are also necessary: the position of the foot at the time of injury and the direction of the deforming force.

Magnetic resonance imaging in brachial plexus injury.

Brachial plexus injury represents the most severe nerve injury of the extremities. While obstetric brachial plexus injury has showed a reduction in the number of cases due to the improvements in obstetric care, brachial plexus injury in the adult is an increasingly common clinical problem. The therapeutic measures depend on the pathologic condition and the location of the injury: Preganglionic avulsions are usually not amenable to surgical repair; function of some denervated muscles can be restored with nerve transfers from intercostals or accessory nerves and contralateral C7 transfer. Postganglionic avulsions are repaired with excision of the damaged segment and nerve autograft between nerve ends or followed up conservatively. Magnetic resonance imaging is the modality of choice for depicting the anatomy and pathology of the brachial plexus: It demonstrates the location of the nerve damage (crucial for optimal treatment planning), depicts the nerve continuity (with or without neuroma formation), or may show a completely disrupted/avulsed nerve, thereby aiding in nerve-injury grading for preoperative planning. Computed tomography myelography has the advantage of a higher spatial resolution in demonstration of nerve roots compared with MR myelography; however, it is invasive and shows some difficulties in the depiction of some pseudomeningoceles with little or no communication with the dural sac.

Intestinal Ischemia: US-CT findings correlations.

BACKGROUND: Intestinal ischemia is an abdominal emergency that accounts for approximately 2% of gastrointestinal illnesses. It represents a complex of diseases caused by impaired blood perfusion to the small and/or large bowel including acute arterial mesenteric ischemia (AAMI), acute venous mesenteric ischemia (AVMI), non occlusive mesenteric ischemia (NOMI), ischemia/reperfusion injury (I/R), ischemic colitis (IC). In this study different study methods (US, CT) will be correlated in the detection of mesenteric ischemia imaging findings due to various etiologies. METHODS: Basing on experience of our institutions, over 200 cases of mesenteric ischemia/infarction investigated with both US and CT were evaluated considering, in particular, the following findings: presence/absence of arterial/venous obstruction, bowel wall thickness and enhancement, presence/absence of spastic reflex ileus, hypotonic reflex ileus or paralitic ileus, mural and/or portal/mesenteric pneumatosis, abdominal free fluid, parenchymal ischemia/infarction (liver, kidney, spleen). RESULTS: To make an early diagnosis useful to ensure a correct therapeutic approach, it is very important to differentiate between occlusive (arterial,venous) and nonocclusive causes (NOMI). The typical findings of each forms of mesenteric ischemia are explained in the text. CONCLUSION: At present, the reference diagnostic modality for intestinal ischaemia is contrast-enhanced CT. However, there are some disadvantages associated with these techniques, such as radiation exposure, potential nephrotoxicity and the risk of an allergic reaction to the contrast agents. Thus, not all patients with suspected bowel ischaemia can be subjected to these examinations. Despite its limitations, US could constitutes a good imaging method as first examination in acute settings of suspected mesenteric ischemia.

Comparison of iodinated contrast media for the assessment of atherosclerotic plaque attenuation values by CT coronary angiography: observations in an ex vivo model.

OBJECTIVE: To compare the influence of different iodinated contrast media with several dilutions on plaque attenuation in an ex vivo coronary model studied by multislice CT coronary angiography. METHODS: In six ex vivo left anterior descending coronary arteries immersed in oil, CT (slices/collimation 64×0.625 mm, temporal resolution 210 ms, pitch 0.2) was performed after intracoronary injection of a saline solution, and solutions of a dimeric isosmolar contrast medium (Iodixanol 320 mgI ml(-1)) and a monomeric high-iodinated contrast medium (Iomeprol 400 mgI ml(-1)) with dilutions of 1/80 (low concentration), 1/50 (medium concentration), 1/40 (high concentration) and 1/20 (very high concentration). Two radiologists drew regions of interest in the lumen and in calcified and non-calcified plaques for each solution. 29 cross-sections with non-calcified plaques and 32 cross-sections with calcified plaques were evaluated. RESULTS: Both contrast media showed different attenuation values within lumen and plaque (p<0.0001). The correlation between lumen and non-calcified plaque values was good (Iodixanol r=0.793, Iomeprol r=0.647). Clustered medium- and high-concentration solutions showed similar plaque attenuation values, signal-to-noise ratios (SNRs) (non-calcified plaque: medium solution SNR 31.3±15 vs 31.4±20, high solution SNR 39.4±17 vs 37.4±22; calcified plaque: medium solution SNR 305.2±133 vs 298.8±132, high solution SNR 323.9±138 vs 293±123) and derived contrast-to-noise ratios (p>0.05). CONCLUSION: Differently iodinated contrast media have a similar influence on plaque attenuation profiles. ADVANCES IN KNOWLEDGE: Since iodine load affects coronary plaque attenuation linearly, different contrast media may be equally employed for coronary atherosclerotic plaque imaging.

Lubricin is expressed in chondrocytes derived from osteoarthritic cartilage encapsulated in poly (ethylene glycol) diacrylate scaffold.

Osteoarthritis (OA) is characterized by degenerative changes within joints that involved quantitative and/or qualitative alterations of cartilage and synovial fluid lubricin, a mucinous glycoprotein secreted by synovial fibroblasts and chondrocytes. Modern therapeutic methods, including tissue-engineering techniques, have been used to treat mechanical damage of the articular cartilage but to date there is no specific and effective treatment. This study aimed at investigating lubricin immunohistochemical expression in cartilage explant from normal and OA patients and in cartilage constructions formed by Poly (ethylene glycol) (PEG) based hydrogels (PEG-DA) encapsulated OA chondrocytes. The expression levels of lubricin were studied by immunohistochemistry: i) in tissue explanted from OA and normal human cartilage; ii) in chondrocytes encapsulated in hydrogel PEGDA from OA and normal human cartilage. Moreover, immunocytochemical and western blot analysis were performed in monolayer cells from OA and normal cartilage. The results showed an increased expression of lubricin in explanted tissue and in monolayer cells from normal cartilage, and a decreased expression of lubricin in OA cartilage. The chondrocytes from OA cartilage after 5 weeks of culture in hydrogels (PEGDA) showed an increased expression of lubricin compared with the control cartilage. The present study demonstrated that OA chondrocytes encapsulated in PEGDA, grown in the scaffold and were able to restore lubricin biosynthesis. Thus our results suggest the possibility of applying autologous cell transplantation in conjunction with scaffold materials for repairing cartilage lesions in patients with OA to reduce at least the progression of the disease.

Computed tomography coronary angiography vs. stress ECG in patients with stable angina.

PURPOSE: This study compared the role of multislice computed tomography coronary angiography (MSCT-CA) and stress electrocardiography (ECG) in the diagnostic workup of patients with chronic chest pain. MATERIALS AND METHODS: MSCT-CA was performed in 43 patients (31 men, 12 women, mean age 58.8+/-7.7 years) with stable angina after a routine diagnostic workup involving stress ECG and conventional CA. The following inclusion criteria were adopted: sinus rhythm and ability to hold breath for 12 s. Beta-blockers were administered in patients with heart rate>or=70 beats/minute. In order to identify or exclude patients with significant stenoses (>or=50% lumen), we determined posttest likelihood ratios of stress test and MSCT-CA separately and of MSCT-CA performed after the stress test. RESULTS: The pretest probability of significant coronary artery disease (CAD) was 74%. Positive and negative likelihood ratios were 2.3 [95% confidence interval (CI) 1.0-5.3] and 0.3 (95% CI: 0.2-0.7) for the stress test and 10.0 (95% CI: 1.8-78.4) and 0.0 (95% CI: 0.0-infinity) for MSCT-CA, respectively. MSCT-CA increased the posttest probability of significant CAD after a negative stress test from 50% to 86% and after a positive stress test from 88% to 100%. MSCT-CA correctly detected all patients without CAD. CONCLUSIONS: Noninvasive MSCT-CA is a potentially useful tool in the diagnostic workup of patients with stable angina owing to its capability to detect or exclude significant CAD.

Cementoplasty in the management of painful extraspinal bone metastases: our experience.

PURPOSE: The aim of this study was to demonstrate the effectiveness of interventional techniques in the palliative management of painful extraspinal bone metastases. MATERIALS AND METHODS: Cementoplasty alone or in combination with radiofrequency (RF) ablation was performed in 14 skeletal extravertebral segments in 13 patients with ages ranging from 50 to 74 (average 67) years. The primary tumours were myeloma (n=5), renal carcinoma (n=5), hepatocellular carcinoma (n=2) and bladder carcinoma (n=2). Metastases were located at the acetabulum (n=4), femur (n=5), humerus (n=1), scapula (n=2) and iliac bone (n=2). The clinical indication was a pain intensity score >4 on the visual analogue scale (VAS) partially or totally refractory to analgesic medication. Clinical evaluation was based on clinical and neurological conditions before and immediately after the procedure and during the follow-up. RESULTS: Technical success was achieved in all cases. Ten patients were treated by cementoplasty alone and four cases by cementoplasty combined with RF ablation. After treatment, all patients experienced improved symptoms, as demonstrated by the VAS score, which remained constant during follow-up. All patients were followed for between 2 and 14 (average 6.1) months. We had one major complication in a patient who developed an abscess, which was treated by percutaneous drainage. CONCLUSIONS: In our experience, cementoplasty alone for small lesions or combined with RF ablation in larger lesions is an effective and safe therapy in the palliative management of painful extraspinal bone metastases.

[Computed tomography evaluation of urothelial carcinomas of the upper urinary tract]. / Valutazione con Tomografia Computerizzata dei carcinomi uroteliali delle vie escretrici urinarie superiori.

Computed Tomography (CT) is an indispensable noninvasive method for staging transitional cell carcinomas of renal pelvis and ureter. Twenty-seven patients with upper urinary tract tumors were examined and the CT results correlated with histopathologic findings. These tumors exhibit three different development patterns: in our series we identified 17 intraluminal sessile lesions, 6 focal or concentric wall thickenings and finally 7 infiltrating masses; soft-tissue density lesions exhibited in all cases mild contrast enhancement (mean density increase: 38 HU). Even though the attenuation values of tumors do not allow the accurate demonstration of the depth of renal pelvis and ureteral wall invasion, CT can differentiate the lesions which are still confined within the external wall layers (CT1, 17 cases) from those invading the peripelvic-ureteral fat (CT2, 9 cases) or spreading to other organs as well as distant metastases (CT3, 4 cases). Delayed scans can also demonstrate intraluminal lesion extent and sometimes changes of patients' position allow better differentiation of wall outlines from peripheral fat. The overall staging accuracy of CT was 76.66% and its sensitivity was 93.33%. The assessment of lymph node metastases was the major cause of error in the CT evaluation of these tumors.

[Magnetic resonance in the evaluation of parametrial involvement in carcinoma of the cervix uteri]. / La risonanza magnetica nella valutazione del coinvolgimento parametriale nel carcinoma della cervice uterina.

Cervical carcinoma is one of the most frequent gynecologic malignancies. Its prognosis depends on both tumor volume at diagnosis and its stage. Staging accuracy is important not only for prognosis but also for optimal treatment planning. According to FIGO criteria, carcinomas without parametrial involvement (stage I and limited stage IIA disease) can be surgically treated. For more advanced stages, treatment, in most cases, consists of radiation therapy or chemotherapy alone. The authors evaluated MR accuracy in the diagnosis of parametrial involvement; to this purpose, 32 patients with histologically proven lesions were referred for MR imaging, which was performed with a 0.5 T superconductive magnet. Transverse and sagittal SE images were obtained with T2 weighting (TR 1800 ms, TE 30-100 ms); transverse and sometimes sagittal images were obtained with T1 weighting (TR 450/300 ms, TE 20/30). T1-weighted images distinguished neoplasm from cervical stroma or dense parametrial connective tissue in 40% of cases only. T2-weighted images, instead, demonstrated the difference in all cases, showing tumor as a hyperintense area in 90% of patients. Neoplastic involvement of pericervical connective tissue was diagnosed, with those sequences, on the basis of focal disruptions of the outer hypointense fibrous cervical stroma; findings were correlated with those from a previous clinical staging and in 26/32 patients with pathologic findings. MR accuracy in demonstrating parametrial involvement was 88%, sensitivity was 77% and specificity was 94%. Clinical staging accuracy in the evaluation of this parameter was 66%. In 6 cases with no surgical findings, MR confirmed extensive parametrial and vesical or rectal neoplastic involvement, as diagnosed at clinics. MR imaging, thanks to its multiplanar and multiparametric imaging capabilities is a very reliable technique in the preoperative staging of cervical carcinoma. Moreover, since clinical staging can sometimes underestimate pericervical connective spread, the higher accuracy of MR imaging can help avoid useless interventional procedures.
