摘要
目的探讨多层螺旋CT对无症状肾癌的早期诊断价值,并分析其CT影像特点。方法收集37例无临床症状且手术病理证实为肾癌的患者,所有患者均行CT平扫及三期增强扫描。结果本组37例肾细胞肾癌,28例为肾透明细胞癌,CT增强后,肾皮质期明显强化,肾实质期及肾盂期强化程度明显减退,呈一过性强化。9例为肾乳头状细胞癌,CT增强后肾实质期及肾盂期强化减退缓慢,呈轻度延迟强化。结论多层螺旋CT平扫及三期增强扫描对无症状肾癌的早期诊断具有重要价值,其CT影像表现具有一定特征性。
Objective To investigate the early diagnostic value of multi-slice spiral CT in the diagnosis of asymptomatic renal cell carcinoma and analyze the characteristics of CT image. Methods To collect 37 cases of patients with renal cell carcinoma without clinical symptoms and surgical pathology. All patients underwent CT plain scan and three phase enhanced scan. Results Renal cell carcinoma in 37 cases,28 cases for small renal cell carcinoma,28 cases of renal clear cell carcinoma. CT enhanced,renal cortex was significantly enhanced,the enhancement of renal parenchyma and renal pelvis phase was significantly decreased,showed a transient enhancement. Nine cases of renal papillary carcinoma,CT enhanced the renal parenchyma and renal pelvis phase enhanced slow decline,mild delayed enhancement. Conclusion Multi slice spiral CT plain scan and three phase enhanced CT scan is of great value in the early diagnosis of asymptomatic renal cell carcinoma,CT image features have some characteristics.
