【Abstract】 Purpose:To evaluate the role of 131 I MIBG in the diagnosis of pheochromocytoma. Methods:The records of 16 inpatients with pheochromocytoma since 1996 were identified. Fourteen were adrenal pheochromocytoma, 2 were abdominal paraganglioms. Ten patients had symptoms such as hypertension, amaurosis, 6 patients had normal or critical blood pressure. Results:Fourteen of sixteen cases were distinguished accurately by Iodine 131 MIBG scintigraphy,including 6 no hypertension cases. All the positive cases were confirmed by post operative biopsy. The specificity of Iodine 131 MIBG scintigraphy was 100%, and sensitivity was 87.5 %. Conclusions:The outstanding accuracy of Iodine 131 MIBG scintigraphy questions the diagnosis of pheochromocytoma preoperatively. And it targets the metabolic information of pheochromocytoma. The marvelous specificity leads to pheochromocytoma diagnosis with every positive case. It should be used as the first choice for the suspected masses.更多还原
