摘要:

Delayed 24-hour scintigraphy was performed in 23 patients. It was found to be useful in enhancing abnormal uptake, enabling better anatomic localization and verifying doubtful uptakes in the 4-hour study. The underlying causes of these observations are probably a better lesion-to-blood ratio and a slow uptake in certain lesions.

摘要:

The cardiac apical mass of Hodgkin's disease, an infrequent presentation of lymphomas, can be selectively labeled with67Ga-citrate. Three cases are presented illustrating the value of67Ga scintigraphy in the differential diagnosis of pericardial masses, as well as its role in the management and assessment of therapy.

摘要:

Sequential supine scintiphotography of the abdomen was performed after intravenous administration of99mTc-pyridoxylideneglutamate (99mTc-PG) to verify the presence of choledochal cyst in an 18-month-old boy who presented with a mass in the right upper quadrant of the abdomen. The total body radioactivity effect, which is similar to the total body opacification during intravenous cholangiography or urography, was clearly demonstrated as a cold area corresponding to the cyst and assisted in the diagnosis. The specific finding was sequential filling of the gallbladder and cyst. In view of the relatively low radiation dose and good physical characteristics of99mTc for imaging,99mTc-PG sequential scintiphotography is useful for the definitive preoperative diagnosis of choledochal cyst in infants and children.

摘要:

A focal defect at the inferior margin of the right lobe of the liver was found in two patients with subhepatic abscesses. This defect must be differentiated from the porta hepatis and the gallbladder fossa. When technetium liver scans are obtained in patients with suspect abdominal abscesses, the inferior margin of the right lobe of the liver should be carefully scrutinized so that right subhepatic abscesses will not be overlooked.

摘要:

Attention is drawn to the various patterns with which the jugular venous reflux may occur in cerebral dynamic studies. The importance of identifying this phenomenon is stressed.

摘要:

Four cases of non-calcifying soft tissue malignant fibrous histiocytoma are presented which showed concentration of99mTc-methylene diphosphonate. Angiography was performed in one of the patients and it featured hypervascularity, tumor staining and early draining veins indicative of arteriovenous shunting. As with other extraskeletal non-calcifying entities which exhibit enhanced uptake of99mTc-phosphate complex, the mechanism of concentration is largely conjectural. Malignant fibrous histiocytoma can be added to the expanding list of conditions which may portray an avidity for99mTc-phosphate complex.

摘要:

A patient with a benign chondroblastoma of the talus bone is described. A review of the pathogenesis and more common sites of predilection of this unusual tumor is presented. This is the first case, to our knowledge, shown by labeled phosphate scanning.
