目的:评价螺旋CT多期扫描在肾癌诊断中的价值。方法:收集21例经手术病理证实的肾癌患者病例资料,分析其螺旋CT平扫及多期增强扫描的影像特征、病理基础。结果:CT平扫中病灶呈等密度或稍低密度6例,稍高密度3例,混杂密度12例。增强扫描皮质期18例明显强化或中等强化,强化均匀或不均匀,3例无明显强化。肾实质期所有病灶强化迅速减退,肾盂期病灶强化进一步减低。有10例肾癌出现肾周邻近脏器侵犯及淋巴结转移。结论:肾癌螺旋CT增强扫描征象有一定特征性,对肾癌的诊断有重要价值,并能准确地对肾癌进行术前分期。
Objective: To evaluate the value of multislice spiral CT in the diagnosis of renal cell carcinoma. Methods: Twenty-one cases of renal cell carcinoma confirmed by surgery and pathology were collected. The imaging features and pathological features of spiral CT scan and multi-phase enhanced scan were analyzed. Results: In CT scan, the lesion showed isodense or lower density in 6 cases, slightly higher density in 3 cases and mixed density in 12 cases. Enhanced scanning of 18 cases of cortical enhancement was significantly enhanced or moderate, even or uneven enhancement, 3 cases without significant enhancement. Renal parenchymal lesion intensified rapidly diminished, further reduction of renal pelvis lesions enhanced. There are 10 cases of renal cell neoplasms adjacent organs and lymph node metastasis. Conclusion: The features of spiral CT enhanced scan in renal cell carcinoma have certain characteristics, which have important value in the diagnosis of renal cell carcinoma, and can accurately preoperatively stage renal cell carcinoma.
