摘要
目的:探讨64排螺旋CT动态增强扫描对肾癌亚型诊断价值,提高对肾癌的诊断准确率。方法:22例经手术病理证实的肾癌(其中透明细胞癌11例,乳头状癌4例,嫌色细胞癌7例)进行动态增强CT扫描。对CT图像资料进行分析,对肿瘤直径大小、强化程度与方式等情况进行分析。结果:乳头状癌的平扫期CT值与透明细胞癌和嫌色细胞癌差异均无统计学意义(P>0.05)。透明细胞癌的皮髓期、实质期及排泄期CT值均明显高于嫌色细胞癌和乳头状癌(P<0.01)。嫌色细胞癌和乳头状癌在平扫期、皮髓期、实质期及排泄期CT值差异均无统计学意义(P>0.05)。结论:不同的肾癌亚型强化程度具有一定特征性鉴别诊断价值。
Objective ：To explore the value of dynamic scanning with 64 slice spiral CT scan in the diagnosis of the subtype of renal cell carcinoma（ RCC）, and improve its diagnostic accuracy. Methods ：Twenty-two patients with RCC diagnosed by pathology（ including 11 cases of clear cell RCC ,4 cases of papillary RCC and 7 cases of chromophobic cell RCC） were treated with dynamic enhancement scanning of 64 slice spiral CT. The tumor diameter, enhancement degree and mode were analyzed by CT imaging. Results： The differences of the CT value of plain scan between the papillary RCC, clear cell RCC and chromophobic cell RCC were not statistically significant（P 〉0.05 ）. The CT value in clear cell RCC during the corticomedullary phase, parenchymal phase and excrete phase were significantly higher than those in papillary RCC and chromophobic cell RCC （ P 〈 0.0I ）. The differences of the CT value between papillary RCC and chromophobic cell RCC during the corticomedullary phase, parenchymal phase and excrete phase were not statistically significant（P 〉0.05）. Conclusions ：The enhance degree of different hypotype RCC has a certain diagnosis and differential diagnosis value in hypotype of RCC.
