Utility of Follow-Up of 131I-MIBG Scintigraphy to Screen Pheochromocytoma

Utility of follow-up of 131I-MIBG scintigraphy to screen pheochromocytoma.

In December 2001, a 49-year-old man presented for evaluation of a gallstone. Abdominal contrast-enhanced computed tomography (CT) incidentally revealed a heteroge-nous mass measuring 36 mm in diameter in the left adrenal lesion, which was suspected of being pheochromocytoma (Picture 1A, arrow). Serum adrenaline, noradrenaline,

99mTc-HYNIC-TOC scintigraphy is superior to 131I-MIBG imaging in the evaluation of extraadrenal pheochromocytoma.

UNLABELLED In this investigation, the efficacy of scintigraphy using (99m)Tc-labeled hydrazinonicotinyl-Tyr3-octreotide (HYNIC-TOC) in the evaluation of extraadrenal pheochromocytoma was assessed and compared with (131)I-labeled metaiodobenzylguanidine (MIBG) imaging. METHODS Ninety-seven patients who were suspected of having pheochromocytoma but showed no definite adrenal abnormalities on CT...

Chromogranin A assay and (131)I-MIBG scintigraphy for diagnosis and follow-up of pheochromocytoma.

UNLABELLED We assessed the performance of a new serum chromogranin A (CgA) assay in combination with the results of (131)I-metaiodobenzylguanidine (MIBG) scintigraphy for diagnosis and follow-up in 89 patients with clinical findings suggestive of pheochromocytoma. METHODS The study population consisted of 41 patients with proven pheochromocytoma and 48 patients with refuted pheochromocytoma. ...
