Octreotide-scintigraphy is a disease-activity parameter in Graves' ophthalmopathy.
OBJECTIVE It is thought that immunosuppressive treatment of Graves' ophthalmopathy should be restricted to patients with active eye disease, but assessing disease activity is difficult. Octreotide scintigraphy has been claimed to differentiate active from inactive disease. Here we study the intraobserver variability and diagnostic accuracy of the quantitative measurement of orbital octreotide u...
متن کاملMassive hepatomegaly in 99mTc-octreotide scintigraphy: The value of 99mTc-sulfur colloid scan
99mTc-octreotide scintigraphy, performed during the following up a 58-year old man with neuroendocrine tumor demonstrated massive hepatomegaly demonstrating multiple areas of increased and decreased uptake. Due to severe hepatomegaly concurrence of any other abdominal soft tissue lesions could not be excluded. A 99mTc-sulfur colloid scan was done and thoroughly compared wi...
متن کاملEffect of chemotherapy on somatostatin receptor detection with octreotide scintigraphy in hormone-refractory prostate cancer patients.
BACKGROUND Neuroendocrine cells have been found in all stages of prostate cancer. Neuroendocrine differentiation of prostate adenocarcinoma is a possible target for therapeutic strategies, such as administration of GH analogs (e.g., somatostatin), especially in patients with hormone-refractory prostate cancer (HRPC). The presence of receptors for these drugs in tumor cells and tissues is essent...
متن کاملComparison of octreotide scintigraphy and conventional imaging in medullary thyroid carcinoma.
UNLABELLED We evaluated the clinical utility of positive somatostatin receptor scintigraphy in patients with medullary thyroid cancer (MTC). METHODS Twenty-four MTC patients with increased calcitonin levels underwent somatostatin receptor scintigraphy using 111In-pentetreotide (120-200 MBq) with early (4 hr after injection) and delayed (24 hr) whole-body scans and liver SPECT imaging. In Grou...
متن کامل68Ga-DOTA-Tyr3-octreotide PET in neuroendocrine tumors: comparison with somatostatin receptor scintigraphy and CT.
UNLABELLED The aim of this study was to evaluate the diagnostic value of a new somatostatin analog, (68)Ga-labeled 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid-d-Phe(1)-Tyr(3)-octreotide ((68)Ga-DOTA-TOC), for PET in patients with known or suspected neuroendocrine tumors. PET was compared with conventional scintigraphy and dedicated CT. METHODS Eighty-four patients (48 men, 3...
