| 摘 要： | 目的：应用超声背向散射积分(IBS)技术对膀胱癌和膀胱内凝血块二维图像进行定量分析比较，评价该技术在二者鉴别诊断中的应用价值。
方法：对32例膀胱癌和18例膀胱内凝血块的患者,分别测量肿物及膀胱内凝血块的IBS值及其标化值(IBS%)，全部病例与手术或膀胱镜结果对照。
结果：膀胱癌组和膀胱内凝血块组平均图像强度（AII）、峰-峰强度（PPI）和图像强度标准差（SDI）比较差异均有显著性（P<0.01）；膀胱癌组标化IBS%值明显高于凝血块组，PPI和SDI值明显低于凝血块组。
结论：超声背向散射积分在膀胱癌和膀胱内凝血块鉴别诊断中有一定的应用价值。

| Abstract: | Objective To analyze quantitatively two-dimensional sonography of bladder cancer and clot with integrated backscatter(IBS) to evaluate its applied value in differential diagnosis of ladder cancer and clot.(Methods The IBS) and IBS% were measured in 32 patients with bladder cancer and 18 patients with bladder clot.(Results There were) significant differences of average image intensity(AII),peak to peak intensity(PPI) and standard deviation of image intensity(SDI) between bladder cancer and clot(P<0.01).IBS% of bladder cancer was higher than those of bladder clot,but PPI and SDI were lower than those of clot significantly.Conclusion IBS plays an important role in differential diagnosis of bladder cancer and clot. |
