【摘要】：目的探讨查肾嫌色细胞癌(chromophobe renal cell carcinoma,CRCC)在MSCT腹部常规双期增强扫描中的强化特征。方法对17例CRCC在腹部常规双期增强扫描中的CT表现,计算并比较CRCC病灶实质和正常肾皮质在平扫、动脉期、静脉期的CT值,病灶在动静脉期的强化程度以及病灶实质与肾皮质的强化比值。结果 CRCC肿块在平扫时密度稍高于或低于正常肾实质,两者差异无统计学意义(P=0.073);动脉期和静脉期,肿块轻到中度均匀强化,增强后各期的CT值显著低于正常肾皮质(P=0.015,0.001);肿块在动静脉期与平扫比较后的强化值,以及与正常肾皮质的强化比值未见显著差异(P0.05);CRCC在动静脉期的强化模式呈"均匀型",而肾实质呈"渐升型"。结论肾CRCC在腹部常规双期增强扫描动脉期呈轻中度均匀强化,静脉期持续强化,动静脉期强化值均显著低于肾皮质,呈"均匀型""反转型"强化模式。
[Abstract]:Objective to investigate the detection of chromophobe renal cell carcinoma in renal chromophobe carcinoma. Methods CT findings of 17 cases of CRCC in abdominal routine dual phase enhanced scan were studied. Computed and compared the CT values of CRCC focus parenchyma and normal renal cortex in plain scan, arterial phase and venous phase. The enhancement degree of the lesion in the arteriovenous phase and the enhancement ratio of the lesion parenchyma to the renal cortex. Results the density of the CRCC mass was slightly higher or lower than that of the normal renal parenchyma during plain scan. There was no significant difference between the two groups. In arterial and venous phases, the mass was enhanced evenly from mild to moderate, and the CT value of each phase after enhancement was significantly lower than that in normal renal cortex. There was no significant difference in the enhancement value of the mass between the arteriovenous phase and the plain scan and the enhancement ratio between the mass and the normal renal cortex (P 0.05). The enhancement pattern of CRCC in arteriovenous phase was "homogeneous", while that of renal parenchyma was "progressive". Conclusion Renal CRCC shows mild to moderate homogeneous enhancement in arterial phase and continuous enhancement in venous phase in abdominal routine dual-phase enhanced arterial phase. The enhancement value of arteriovenous phase was significantly lower than that of renal cortex.
