Magnetic resonance imaging with gadolinium DTPA assessment of bladder carcinoma and its response to treatment

Selection of appropriate managemenetof bladder carcinoma depends on accurate staging. Cystoscope and examination under anaesthesia are limited in their ability to assess deep tumour extension, extravesical spread and quite often radiotherapy bladder distortion by fibrosis and oedema obscure residual and recurrent tumour. MRI is accurate in staging of bladder carcinoma, the ability of Gd-DTPA-enhanced MRI it identify and define the extent of primary bladder carcinoma and to evaluate response to treatment in patients receiving and to detect residual and recurrent tumour after was also mentioned in this study

Colour flow mapping in the diagnosis of the calf deep vein thrombosis

A prospective trial organized to evaluate the role of color flow Doppler ultrasound techniques, comparable with ascending phlebography in the diagnosis of deep vein thrombosis [DVT] with particular reference to isolated calf lesion

Sonography in evaluation of male anterior urethra

Ultrasonography offers advantages over conventional urethrography in terms of abnormalities detected, convenience of the study and lack of ionizing radiation. Our study favours sonography to be the examination of choice for both follow up of postoperative patients and for the evaluation of patients with new symptoms. The urologist may require a "road map" before surgery and for this purpose contrast urethra-gram may be more helpful

Sonographic diagnosis of portal vein invasion in patients with hepatocellular carcinoma: comparison with arterial portography

The role of ultrasound as noninvasive technique in sonographic assessment of main portal vein compared with arterial protography, was documented in 20 patients with established hepatocelular carcinoma

Chest high resolution computed tomography in AIDS patients

HRCT was performed on 10 homosexual men with acquired immunodeficiency syndrome [AIDS]. All had bronchoscopically proven pneumocystis carinii pneumonia [PCP]. Five patients were re-scanned following treatment and symptomatic recovery

Role of magnetic resonance imaging in investigation of undescended testes

Location of undescended testis is important because of the greatly increased risk of malignancy. Various imaging methods have been used in the past with only partial success. In many cases an exploratory laparotomy was performed although even this has not proved to be completely successful. The use of MRI in 10 adult patients with 10 undescended testes is described. It is possible to locate the position in 8 from these 10 patients by this method. MRI does not use ionizing radiation and is a useful method for determination of these radio-sensitive organs

Ultrasound changes of gall bladder wall pathology: a sonographic-pathological correlation

Changes taking place within walls of pathologic gallbladder were sonographically evaluated and analyzed on pathological basis. These changes were considered to be valuable signs in discriminating and grading gallbladder disease

Role of ultrasound in evaluation of empty gestational sac before threatened abortion

Threatened abortion occurs during the first 20 weeks of pregnancy when vaginal bleeding is encountered with closed cervical os. This occurs in 20 to 52% of pregnancies. Ultrasound provides a simple and unique method of visualizing pregnancy in early stages. If the viability of pregnancy can be accurately determined a more active line of management can take place. Nonviable pregnancies are managed by uterine evacuation, whereas viable pregnancies are observed

Role of ultrasound in assessment of foetal abnormalities during pregnancy

The role of ultrasound in early demonstration of fetal abnormalities and its effect on obstetric practice is discussed in this work, thus possessing great benefit during antenatal care

Radiological changes in nondialysed patients with chronic renal failure

Skeletal abnormalities in renal osteodystrophy include osteomalacia osteosclerosis, cortical and subperiosteal bony erosions, abnormal bony texture [rarefaction], bone deformities and brown tumour. On the other hand soft tissue calcifications are another prominent feature of chronic renal diseases. They may be present in vessels subcutaneus tissue and viscera [heart, lungs, and kidneys]. Large globular periarticular calcifications may also be seen. Sixteen patients with chronic renal failure with secondary bony and soft tissue changes are discussed thoroughly in this series

Dysmorphic right lung

Dysmorphic lung is a term introduced to describe any congenital malformation in the form of hypoplasia of right lung with anomalous venous drainage and systemic arterial supply of variable degree. The scimitar anomaly is the commonest type of this condition. However, the syndrome is extended to include cases where one of the triad is absent. Our own experience in eight cases with dysmorphic right lung is presented and carefully discussed

Radiological imaging of chronic pancreatitis

Ten cases with chronic pancreatitis were demonstrated by different recent modalities i.e. Computed tomography [C T], endoscopic regrade pancreatography [ERP], endoscopic retrograde cholangiopancreatography [ERCP] and ultrasonography and isotope scanning. Most diagnostic criteria in demonstration of chronic forms of pancreatitis were thoroughly discussed
