摘　　要：目的探讨超声造影提高疑难肾肿瘤检出率的临床价值。方法常规超声显示困难的36个肾肿瘤行超声造影检查,均经手术及病理证实。先行常规超声观察肿瘤的大小、回声、边界、血流信号、血管位置等,超声造影观察病灶的增强方式、增强表现、增强的均匀度、假包膜的显示等,建立肾肿瘤造影前后病灶明显性评分标准并计算。结果常规超声显示27个肿瘤边界欠清或不清,18个内部呈等回声,19个显示内部或周边血流信号,余无明显彩色血流信号。超声造影后在病灶的边界、内部回声和血供明显性方面大有改善,差异具有统计学意义(P<0.05)。造影后疑难肾肿瘤病灶的明显性积分高于造影前,差异具有显著统计学意义(P<0.01)。结论超声造影能明显提高疑难肾肿瘤病灶的检出率,优于常规超声。Objective To investigate the value of contrast-enhanced sonography （CEUS） in improving the detec- tion rate of difficult renal tumors. Methods Thirty six difficult renal tumors by conventional ultrasound （US） were scanned by CEUS. All tumors were confirmed by operation and pathology sequentially. For each tumor, the tumor size, inner echoes, boundary, blood signal of tumors and its location were observed by conventional US. The modality of enhancement, enhancement appearance, the homogeneity of enhancement and the presence of pseudocapsule were studied by CEUS. The assessment criteria of visibility of difficult renal tumors was established and calculated before and after CEUS. Results Twenty seven renal tumors of ill-defined margin and 18 isoechoic tumors were displayed by conventional US. Intratumoral or peritumoral blood signal was observed in 19 cases, and the rest cases did not show any blood signal yet. The visibility of difficult renal tumors, including boundary, inner echoes and blood supply, was better identified after CEUS respectively. The change of visibility of difficult renal tumors was statistically significant before and after CEUS（P〈0.05）. The score of visibility of difficult renal tumors after CEUS was significantly higher than that before CEUS（P〈0.01）. Conclusions CEUS is better than the conventional US in significantly improving the detection rate of difficult renal tumors.
