摘要:

67Ga-citrate scan from skull to mid-abdomen showed increased uptake in both parotid glands, mediastinum, lungs, uvei and/or enlarged lacrimal glands. The differential diagnosis of the positive radiogallium scan is discussed with emphasis on the value of the extrathoracic findings. Tissue diagnosis confirmed the imaging diagnosis of sarcoidosis. The case illustrates the usefulness of double radionuclide study—67Ga and99mTc-MAA—and of the tomographic scanner in defining the spread of the active granulomatous disease.

摘要:

An uncommon primary site for an American Burkitt's lymphoma in the nasopharyngeal region was demonstrated by radiogallium imaging in a 14-year-old white boy. Fifth cranial nerve involvement and cerebrospinal fluid cytology for Burkitt's responded initially to four drug chemotherapy with objective reduction in the tumor radiogallium uptake. Clinical relapse and recurrence of the tumor radiogallium uptake in less than three weeks following the completion of therapy was observed. Local irradiation and chemotherapy successfully reduced the symptoms and eliminated the radiogallium tumor uptake. Radiogallium imaging is advocated as a principal method for staging and monitoring the course of Burkitt's lymphoma.

摘要:

Regional enteritis in a 41-year-old woman was localized on a67Ga-citrate scan, appearing as a wellcircumscribed abnormality in the pelvis simulating an abscess or a malignant neoplasm. Gallium-67-citrate scintigraphy is useful in localizing granulomatous inflammations including regional enteritis, and its use may be beneficial in evaluating the extent and the state of disease process.

摘要:

After a photon-deficient area in the region of the stomach under the ribs on the left side was noted in some bone-scanning patients, a successful attempt was made to produce the artifact by having a cooperative patient eat a large lunch. The comparison of the scans before and after lunch showed the presence of a postprandial artifact in the area in question. It is important not to confuse this artifact with a space-occupying avascular mass in that part of the abdomen.

摘要:

A case of total superior vena cava obstruction and “hot spot” in the liver demonstrated by a radiocolloid liver scan in a case of non-Hodgkin's lymphoma of the anterior mediastinum, is presented. The study showed total obstruction of the superior vena cava and the presence of collateral circulation. The patient received radiation therapy, and a subsequent radiocolloid study showed relief of the obstruction and disappearance of the “hot spot.”

摘要:

The purpose of this investigation was to determine the diagnostic value (validity) of technetium-99mpyridoxylideneglutamate cholescintigraphy (99mTc- PGC) in patients with and without cholecystitis and to compare its validity to those of oral cholecystography (OC) and ultrasonography (US).99mTc-PGC was applied to 50 patients with acute, subacute, and/or chronic cholecystitis with cystic duct obstruction proven histologically and operatively, and also to 27 non-diseased volunteers and 43 patients with right upper quadrant abdominal pain who subsequently were proven free of gallbladder disease. In addition, 38 patients had OC, and 31 had US performed. The results shows that the sensitivity and specificity of99mTc-PGC were 100%. Whereas for OC the sensitivity was 87%, specificity was 100%. For US the sensitivity was 70%, and specificity was 93%. The repeatability of99mTc-PGC, OC, and US were 100%, 94% and 81% respectively. These data show that99mTc-pyridoxylideneglutamate cholescintigraphy is a valid diagnostic tool in the evaluation of patients with cholecystitis, and is also safe and simple.

摘要:

Findings on thyroid scintigram were compared with results of thyroid palpation and size and location of C-cell disease in 68 thyroid lobes of 35 patients with familial medullary thyroid carcinoma (MTC) and high basal or stimulated plasma calcitonin values. Rectilinear scans showed cold nodules in 24 (35%) of 68 lobes. In three lobes, the cold nodules did not coincide with MTC (2 macrofollicular adenomas, 1 colloid goiter). Thus, the true positive rate for rectilinear scans was 31%. Palpation identified nodules in 20 lobes (29%), but the true positive rate was only 26%. Patients with MTC have high basal or stimulated calcitonin values long before the tumor is detectable by scan or even later by palpation. When the tumors were large enough to be seen on thyroid scans, the most frequently encountered single pattern was that of symmetrically located cold nodules in the middle of otherwise normal thyroid lobes. This pattern, if encountered in a thyroid scan, should raise the suspicion of MTC.
