多层螺旋CT与MRI在嗜铬细胞瘤诊断中的价值

目的 探讨多层螺旋CT与MRI在嗜铬细胞瘤诊断中的价值.方法 经手术证实、同时具备CT和MRI影像资料的嗜铬细胞瘤患者25例,对所有患者分别行多层螺旋CT和MRI检查,其中MRI检查包括常规T1加权成像、T2加权成像、梯度回波反相位或钆-二亚乙基三胺五乙酸增强T1加权成像.对20例患者行螺旋CT增强动脉期、静脉期及延迟...

The value of CT and MRI in diagnosis of pheochromocytoma

Objective To explore the value of CT and MRI in diagnosis of pheochromocytoma.Methods Tweenty-five cases of pheochromocytoma confirmed by operation owned both CT and MRI image materials.All cases were underwent multi-slice spiral CT and MRI.MRI included T1 weighted imaging,T2 weighted imaging,gradient-echo out of phase or gadolinium-diethylenetriamine pentaacetic acid enhanced T1 weighted imaging.Tri-phase enhancement spiral CT was performed in 20 patients.Results Among all the 25 cases of pheochromocytoma,23 occured in the adrenal gland,1 occured beside the abdominal aorta,another beside the mediastinum muscle column.22 cases were benign,3 cases were malignant.Multi-slice spiral CT and MRI images showed the shape of a oval like,lobulated and irregular edge,partially showed necrosis,cystic lesion and bleeding.CT post-treatment and MRI can clearly show the shape,internal structure,adjacent relationship and partial tissue composition of tumors.Conclusion Multi-slice spiral CT and MRI can improve the diagnostic accuracy rate of pheochromosytoma.
