Difficult diagnosis and localization of focal nesidioblastosis: clinical implications of 68Gallium-DOTA-D-Phe1-Tyr3-octreotide PET scanning
Focal nesidioblastosis is a rare cause of endogenous hyperinsulinemic hypoglycemia in adults. Because it is difficult to localize and detect with current imaging modalities, nesidioblastosis is challenging for biliary-pancreatic surgeons. (68)Gallium-DOTA-D-Phe(1)-Tyr(3)-octreotide PET scanning and (111)indium-pentetreotide diethylene triamine pentaacetic acid octreotide scanning may be superio...
متن کامل68Ga-DOTA-D Phe1-Tyr3-Octreotide (DOTATOC)-PET/CT in a Suspected Case of Recurrent Meningioma
We present a case of 45-year-old female who presented with headache for last 1 month. She was a follow-up case of left frontal meningioma that was operated 4 years back. CEMRI of the brain suggested post-surgical changes with no obvious enhancing residual/recurrent lesion. The patient was then referred for 68 Ga DOTANOC PET/CT to rule out recurrent disease. PET/CT revealed a focus of somatostat...
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...
متن کاملFailure of functional imaging with gallium-68-DOTA-D-Phe1-Tyr3-octreotide positron emission tomography to localize the site of ectopic adrenocorticotropic hormone secretion: a case report
INTRODUCTION The diagnostic efficacy of biochemical and imaging modalities for investigating the causes of Cushing's syndrome are limited. We report a case demonstrating the limitations of these modalities, especially the inability of functional imaging to help localize the site of ectopic adrenocorticotropic hormone secretion. CASE PRESENTATION A 37-year-old Arabian woman presented with 12 m...
متن کاملSomatostatin receptor imaging in patients with neuroendocrine tumors: not only SPECT?
In this issue of The Journal of Nuclear Medicine, Gabriel et al. (1) report their experience with 68Ga-labeled 1,4,7,10tetraazacyclododecane-N,N9,N99,N999tetraacetic acid-D-Phe1-Tyr3-octreotide (68Ga-DOTA-TOC) PET in a series of 84 patients with neuroendocrine tumors (NET). PET was more accurate with a higher detection rate than somatostatin receptor scintigraphy (using 111In-DOTA-TOC or 99mTc-...
