摘要
目的探讨肾细胞癌的CT、MRI表现,提高肾细胞癌的影像诊断水平。方法回顾性分析22例肾细胞癌患者的CT及MRI表现,13例行CT平扫与增强扫描,14例行MRI平扫与增强扫描,22例病例均经手术病理证实为肾细胞癌。结果 CT检查13例,平扫呈软组织密度,增强后动脉期不均匀强化,肾实质期及延时期呈相对低密度。MRI检查14例,病灶T1WI呈等低信号,T2WI脂肪抑制序列呈高信号,部分呈混杂信号,增强后不均匀强化,囊变坏死区不强化。结论肾癌的影像学表现多种多样,CT分辨率高,可多平面重建,能清楚显示肿瘤的大小、形态、密度及浸润的程度及和周围器官的关系,是目前检查肾癌的最佳检查方法。MRI软组织分辨率高,可以多个序列检查,能清楚显示囊变坏死及肾静脉癌栓。
Objective To study CT and MRI findings of renal cell carcinoma,to improve the radiological diagnosis of renal cell carcinoma.Methods Retrospective analysis of CT and MRI findings of 22 patients with renal cell carcinoma was done.13 cases underwent CT scan and enhanced scan.14 cases underwent MRI plain scan and enhancement scan.22 cases were confirmed by operation and pathology of renal cell carcinoma.Results In 13 CT examination cases,plain scan showed soft tissue density after enhancement,heterogeneous enhancement in the arterial phase,and renal parenchymal phase and delay phase showed relatively low density.In MRI examination 14 cases,T1WI showed low-signal lesions,T2WI fat suppression sequences showed high signal,some showed mixed signal enhancement and heterogeneous enhancement,and cystic necrosis area was not enhanced.Conclusion Renal imaging manifestations varies,has high resolution in CT,with multiple planar reconstruction,which can clearly show the size,shape,density and infiltration and the organs around the tumor.It is currently the best inspection method inspection of renal cell carcinoma.
