Purpose:To discuss the value of16-slice spiral CT contrast enhanced early corticomedullary phase scanning and CT angiography(CTA)in diagnosis and preoperative evaluation of renal cell carcinoma.
目的：探讨16层螺旋CT肾脏皮质早期扫描及血管成像在肾癌定性诊断及术前评估中的价值。
On enhanced ct scanning the density of renal medulla increased, the margin of renal calyces became indistinct.
CT增强扫描肾髓质密度增高，肾小盏界限模糊。
Conclusion: small renal cell carcinoma 4d THRIVE dynamic enhanced scanning, some parameters correlated positively with MVD, VEGF. It has an important value in small renal cell carcinoma angiogenesis.
结论：小肾癌4d THRIVE动态增强扫描部分参数与MVD、VEGF相关，在评价小肾癌血管生成方面有重要价值。
