Thirteen patients' status post repair of thoracic aortic dissection were studied with both magnetic resonance and angiography. MRI was an accurate modality in identifying residual dissection when aortography was used as the gold standard. MRI can be used as a noninvasive modality for the follow-up of these patients.

Two patients who presented with an anterior chest wall mass were evaluated by computed tomography (CT) scan and were found to have an associated thick-walled pleural collection, consistent with empyema necessitatis. In view of the increasing incidence of pulmonary and extrapulmonary Mycobacterium tuberculosis infection, the entity of tuberculous empyema necessitatis should be strongly considered when the described CT findings are present.

In the absence of trauma or descending thoracic aortic dissection, abdominal aortic dissection is rare. This report presents a case of "isolated" abdominal aortic dissection. Magnetic resonance imaging may reliably diagnose and characterize these dissections without the use of contrast material.

A prospective study was undertaken to assess the ability of magnetic resonance imaging (MRI) to stage cervical carcinoma. Compared to computed tomography (CT), MRI showed a high degree of accuracy in correctly demonstrating involvement of the vagina, parametria and sidewalls, bladder, and lymph nodes but tended to overestimate disease in all of the categories studied. Large-scale studies comparing the two modalities are necessary because the most accurate staging of cervical carcinoma is crucial for selecting the best treatment protocols.

A patient with lymphomatoid granulomatosis was examined with both computed tomography (CT) and magnetic resonance imaging (MRI). The CT and MRI character of the pulmonary lesions are described as well as the patient's course and progression to lymphoma.

Three patients with epidural compression of the spinal cord, a rare but serious complication of type I Gaucher disease, are described. In two cases the compression occurred at the lower thoracic region due to collapse of T-11 and T-12, respectively. In the third case, an epidural mass developed at the dorsal aspect of the cord at T-2, and T-2 and T-3 showed diffuse infiltration without collapse. In two cases the diagnosis was made with magnetic resonance (MR) imaging. In these cases MR imaging proved to be a safe, accurate method for demonstrating the nature and extent of disease within the spinal canal.

Upper gastrointestinal series and computed tomography of the abdomen in an elderly women demonstrated a large multiloculated mass in the left subphrenic space that communicated with the fundus. The resected specimen showed histopathological features of bronchopulmonary foregut malformation.

A patient undergoing treatment for abdominal lymphoma presented with a superior vena cava (SVC) syndrome. The presence of a wide mediastinum and "nodular" mediastinal densities on CT presented a diagnostic problem, necessitating thoracotomy. The thoracotomy was negative for tumor or infection. We believe that the presence of an indwelling catheter and mediastinal lipomatosis resulted in the SVC syndrome. The "nodular" densities represented an unusual set of mediastinal collaterals that must be distinguished from adenopathy.

A prospective study was undertaken to evaluate and compare magnetic resonance imaging (MRI) and ultrasound (U/S) in monitoring follicular and endometrial development during the normal menstrual cycle. Results of MRI, U/S, estradiol (E2), and progesterone were obtained from five ovulatory volunteers on days 4, 8, 12, 16, 20, and 24 of the cycle. On U/S, all the women had only one dominant follicle, whereas MRI was able to detect a secondary cohort of follicles in three of five volunteers. Endometrial development on U/S and MRI showed similar patterns of growth with an increase on MRI from 5.8 +/- 1.1 mm on day 4 to a mean peak of 10.3 +/- 1.7 mm on day 24. A distinct feature of MRI was the demonstration of a junctional zone (JZ), which has a pattern of growth that resembles that of the endometrium, with accelerated growth from day 8 to day 16 (5.1 +/- .7 mm to 6.7 +/- .7 mm). The JZ corresponds anatomically to the distribution of the arcuate vessels and may therefore represent changes in blood supply to the endometrium. MRI, similar to U/S, is noninvasive and does not involve any radiation exposure but provides new information on uterine changes in the normal cycle. At present, its clinical applications are limited.
