摘要:

Laparoscopic cholecystectomy has become a popular alternative to traditional open cholecystectomy for uncomplicated, acute cholecystitis. At some centers, laparoscopic cholecystectomy is already the more frequently performed procedure. The presence or suspicion of common bile duct (CBD) stones or obstruction may necessitate conventional surgery or additional procedures. This report describes a patient with acute cholecystitis for whom the surgical management changed based on biliary scintigraphy. The demonstration of an unsuspected CBD obstruction by biliary imaging allowed the surgeon to change the initial plan for laparoscopic cholecystectomy to conventional open surgery. Stones in the common bile duct were removed.

摘要:

This selective retrospective study was undertaken to establish whether the gallbladder contraction (ejection fraction) calculated during cholescintigraphy correlates with the histopathologic changes in the surgical specimen. The medical records of 243 patients who underwent hepatobiliary scintigraphy were reviewed. Of these, 215 patients had cholecystokinin cholescintigraphy and 100 went on to cholecystectomy. The original histologic slides from 67 gallbladders were available and reviewed by a pathologist who graded each specimen based on presence and severity of changes associated with “chronic” cholecystitis. There was no significant correlation between the severity of histopathologic change and cholecystokinin-induced gallbladder emptying.

摘要:

Scintigraphic localization of gastrointestinal protein loss has been recently reported. A noninvasive method for the localization of protein loss in the gut using Tc-99m labeled albumin seems encouraging and is described here. In six patients studied for protein-losing enteropathy, scintigraphic results of four were positive.

摘要:

Tc-99m RBC scintigraphy is known to be useful for the evaluation of gastrointestinal bleeding. The authors describe a patient with a posttraumatic peritoneal tap in whom Tc-99m RBC imaging showed bleeding into the gastrointestinal wall and into the ascitic fluid.

摘要:

A 32-year old man with Hodgkin's disease was admitted to the hospital with a liver mass. The primary diagnostic possibilities, infection and lymphoma, require markedly different therapy. The combination of Ga-67 and ln-111 white blood cell imaging correctly diagnosed the mass as lymphoma.

摘要:

The authors report discordant hepatic uptake of Tc-99m NGA and Tc-99m PMT in a patient with hepatoma. Tc-99m PMT uptake was delayed and Tc-99m NGA concentrated in another area, thereby demonstrating that the uptake mechanisms for Tc-99m NGA and Tc-99m PMT are different. Tc-99m NGA imaging may be useful in characterizing the focal hepatic lesion of Tc-99m IDA or Tc-99m PMT concentration.

摘要:

Aortic arch mycotic aneurysm, an uncommon cause of sepsis, carries a grave prognosis. Clinical presentations as well as laboratory and radiologic examinations may be noncontributory and often misleading. In a patient with a fever of unknown origin, only the radiogallium study could enable an accurate diagnosis and pinpoint the anatomic localization of the mycotic aneurysm as the cause of fever.

摘要:

Progressive aphasia without dementia is a relatively uncommon neurobehavioral syndrome. The initial presentation of progressive aphasia without cognitive impairment may pose a diagnostic dilemma. The authors report a patient with progressive aphasia. The initial neuroimaging studies (MRI, CT) were not diagnostically helpful. However, brain SPECT imaging with Tc-99m HMPAO clearly demonstrated a left temporal lobe abnormality. This report discusses the potential clinical usefulness of brain SPECT imaging in the evaluation of neurobehavioral disorders.

摘要:

An elderly woman with a diffusely enlarged goiter and multiple miliary nodular lesions on chest x-ray showed Ga-67 accumulation in the right thyroid lobe. Histologic findings obtained after total thyroidectomy and open lung biopsy revealed papillary carcinoma in the left lobe with pulmonary metastases and adenomatous nodules in the right lobe. This is the first report of Ga-67 accumulation in adenomatous goiter.

摘要:

The authors performed both Tc-99m HMPAO and TI-201 scintigraphy in 30 patients with thyroid tumors (21 papillary adenocarcinoma, three solid follicular adenoma, six adenomatous goiter with cystic degeneration). Increased accumulation of both Tc-99m HMPAO and TI-201 was seen in 14 patients with papillary adenocarcinoma and three with solid follicular adenoma, whereas two patients with papillary adenocarcinoma had low accumulation of both tracers. Of the six patients with adenomatous goiter with cystic degeneration, four had low accumulation of both Tc-99m HMPAO and TI-201, and one patient had low accumulation of Tc-99m HMPAO only. Iso accumulation (same accumulation as the normal thyroid) of Tc-99m HMPAO was seen in five patients with papillary adenocarcinoma and one with adenomatous goiter. The distribution of Tc-99m HMPAO in the thyroid tumors and normal thyroid tissue was independent of time from 2 to 120 minutes after injection. The results of dynamic studies using Tc-99m HMPAO suggested that the accumulation of Tc-99m HMPAO in thyroid tumors reflected mainly tumor blood flow. The resultant Tc-99m HMPAO images were essentially similar to the TI-201 images obtained 10 minutes after injection. Tc-99m HMPAO imaging can be a suitable substitute for TI-201 imaging, and it may possibly be used to estimate tumor blood flow in patients with thyroid tumors
