In 26 patients with cardiac mass lesions confirmed by surgery, diagnostic imaging was performed preoperatively by means of two-dimensional echocardiography (26 patients), angiography (12 patients), correlative computed tomography (CT, 8 patients), and magnetic resonance imaging (MRI, 3 patients). Two-dimensional echocardiography correctly identified the cardiac masses in all patients. Angiography missed two of 12 cardiac masses; CT missed one of eight. ⋯ However, CT and MRI provided additional information concerning cardiac mural infiltration, pericardial involvement, and extracardiac tumor extension, and should be integrated within a preoperative imaging strategy. Thus two-dimensional echocardiography is the method of choice for primary assessment of patients with suspected cardiac masses. Further preoperative imaging by CT or MRI can be limited to patients with malignancies suspected on the grounds of pericardial effusion or other clinical results.

Computed tomography (CT) was carried out on 70 patients with blunt abdominal trauma. Damage to the abdominal organs was clearly demonstrated by CT. ⋯ Serum GPT levels were significantly elevated in patients with liver damage (p less than 0.001). CT proved to be useful for detecting damage to organs in patients with abdominal trauma.

For many musculoskeletal applications, magnetic resonance imaging (MRI) has gone beyond the stage of a promising new modality to become the imaging technique of choice. Various applications of MRI in the musculoskeletal system are discussed. It is clear that MRI fills an important need and will be a major addition to the field of musculoskeletal diagnosis.

An intraoperative remote afterloading endocurietherapy (ECT) technique with high-activity 60cobalt (60Co) for the treatment of glioblastoma multiforme (GM) is described. The technique can be used for initial management of the unresectable tumor or for retreatment of patients with recurrent tumor who have been treated previously with surgery and postoperative radiotherapy. We present the technique, tumor response, radiographic findings, and survival of 38 glioblastoma patients treated with intraoperative 60Co.

Computed tomography was performed in 27 lesions of follicular adenoma. About half of them showed heterogeneous low density areas due to retrogressive changes, especially internal hemorrhage. ⋯ Internal hemorrhage was another cause of indistinct contour in two lesions. We stress that CT features of follicular adenomas are modified by their retrogressive changes and inflammation of the adjacent gland.
