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、静脉期及延迟期三期扫描.结果 25例嗜铬细胞瘤患者中,肿瘤发生在肾上腺者23例、腹主动脉旁者1例、纵隔脊柱旁者1例,其中良性肿瘤22例、恶性3例.多层螺旋CT与MRI表现为类圆形、分叶状及边缘不规则形,部分伴有坏死、囊变及出血.CT三维重建及MRI多序列成像能清晰显示肿瘤的立体形态、内部结构、毗邻关系及部分组织成分.结论 多层螺旋CT和MRI多序列成像能明显提高嗜铬细胞瘤的诊断准确率.
目的 探討多層螺鏇CT與MRI在嗜鉻細胞瘤診斷中的價值.方法 經手術證實、同時具備CT和MRI影像資料的嗜鉻細胞瘤患者25例,對所有患者分彆行多層螺鏇CT和MRI檢查,其中MRI檢查包括常規T1加權成像、T2加權成像、梯度迴波反相位或釓-二亞乙基三胺五乙痠增彊T1加權成像.對20例患者行螺鏇CT增彊動脈期、靜脈期及延遲期三期掃描.結果 25例嗜鉻細胞瘤患者中,腫瘤髮生在腎上腺者23例、腹主動脈徬者1例、縱隔脊柱徬者1例,其中良性腫瘤22例、噁性3例.多層螺鏇CT與MRI錶現為類圓形、分葉狀及邊緣不規則形,部分伴有壞死、囊變及齣血.CT三維重建及MRI多序列成像能清晰顯示腫瘤的立體形態、內部結構、毗鄰關繫及部分組織成分.結論 多層螺鏇CT和MRI多序列成像能明顯提高嗜鉻細胞瘤的診斷準確率.

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.
