螺旋CT多期扫描在肾癌诊断中的应用价值

Evaluation of multi-phase spiral CT scanning in the diagnosis of renal cell carcinoma

目的探讨螺旋CT多期扫描在肾癌诊断中的应用价值。方法回顾性分析24例肾癌病人的术前螺旋CT多期扫描的资料、手术和病理结果,结合文献资料予以分析。结果CT平扫病灶呈混杂密度11例,低密度9例,稍高密度3例,等密度1例。增强扫描皮质期明显强化21例,轻度强化3例,均呈一过性强化。小肾癌3例,囊性肾癌2例。结合手术和病理24例螺旋CT诊断准确率91.7%(22/24)。结论肾癌螺旋CT多期扫描征象有一定特征性,对肾癌诊断与鉴别诊断有重要价值。

Objective To analyze the value of multi - phase spiral CT scanning in the diagnosis of renal cell carcinoma. Methods Spiral CT findings in 24 patients with renal cell carcinoma with operation and pathology proved, were retrospectively analyzed and combined with reviewing the literature. Results Plain CT scan showed heterogeneous density mass in 11 cases, low density mass in 9 cases, slightly hyperdense mass 3 cases, isodense mass in 1 cases. Contrast CT scan showed marked enhancement in cortical phase in 21 cases, slight enhancement in 3 cases, the masses were enhanced in a temporary course. Small renal cell carcinoma 3 cases, cystic renal cell carcinoma 2 cases. Compared with operation and pathology, the accuracy of spiral CT scan in 24 cases was 91.7% （ 22 of 24）. Conclusion Renal cell carcinoma is of certain characteristic on multi - phase spiral CT contrast - enhanced scan, it is a very valuable method in diagnosis and differential diagnosis of renal cell carcinoma.
