摘要:
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。
Abstract:
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 pheoehromosytoma.
