摘要
目的:对比分析常规超声(二维声像图)和超声造影对肾细胞癌假包膜显示率,以探讨超声造影对肾细胞癌的临床诊断价值。方法:对经手术和病理检查证实的103例肾细胞癌患者,应用常规超声显示瘤体的假包膜,再选用超声造影观察瘤体的假包膜,并计算二种方法的显示率。结果:103例肾细胞癌中,肾细胞透明细胞癌97例,乳头状肾细胞癌6例。超声造影显示假包膜78例(75.7%),而常规超声显示假包膜27例(26.2%),超声造影及常规超声均不显示假包膜者25例,两者间差异有统计学意义(P<0.01)。结论:超声造影对肾细胞癌假包膜显示率明显高于常规超声,故超声造影对肾细胞癌的诊断有重要价值。
Objective： To prospectively analyze visualization rate of pseudocapsule of renal cell carcinoma on contrast-enhanced ultrasound（CEUS）and conventional ultrasound. Methods： 103 patients proved by operation and pathology with renal cell carcinomas were prospectively studied for comparison between CEUS and conventional ultrasound. We compared the detectability of a pseudocapsule in renal cell carcinomas with CEUS and on conven-tional ultrasound, Results： Final diagnoses of the 103 renal cell carcinomas （RCCs） were as follows：renal cell carci-nomas 97, papillary renal cell carcinomas 6. On conventional ultrasound, the presence of a pseudocapsule was detected in 27 of 103 RCCs （26.2%）. CEUS revealed the presence of pseudocapsule in 78 of 103 RCCs（75.7%）. The pseudocapsule in 25 RCCs was not visible on either conventional or CEUS. CEUS in detection of pseudocapsule compared with conventional ultrasound was statistically significant（P〈0.01）. Conclusions： Visualization rate of pseudocapsule on CEUS is more effective than that on conventional ultrasound. CEUS is useful to diagnose of renal cell carcinoma.
