经直肠三维超声在前列腺疾病诊断中的应用

Transrectal Three-dimensional Ultrasonogrphy in The Diagnosis of Prostate Diseases

目的对73例怀疑前列腺疾病的患者进行经直肠三维超声检查,以此探讨经直肠三维超声在前列腺疾病中的应用价值。方法对73例患者进行经直肠三维超声检查,对所检查的前列腺声像图进行三维重建,并与经直肠二维超声检查获得的声像图进行对照。结果经直肠三维超声能清晰显示病灶的立体结构,在立体感及空间位置关系上能提供较二维图像更丰富的信号。三维超声病变检出率为94.5%,二维超声检出率为83.6%,三维超声检出率明显高于二维超声(P<0.05)。结论经直肠三维超声对前列腺疾病的诊断具有较大的临床应用价值。

Objective To discuss the value of three - dimensional （3D） transrectal ultrasound （3DTRUS） in diagnosing prostatic diseases. In this study ,73 patients were examed. Methods 73 patients underwent three - dimensional reconstruction of prostatic ultrason- ic echo were performe. At sametime we did 2DTRUS in these 73 patients. We compare these two groups＂ ultrasonic echo characteristics. Resuits 3DTRUS can provide more detailed three - dimensional makeup of prostatic lesions when compared with 2DTRUS. Overall informa- tive value 3DTRUS in detection of prostatic lesions was 94.5% ,2DTRUS is 83.6%. 3DTRUS produced a significantly higher detection rate （P 〈 0.05） than 2DTRUS did. Conclusions In our experience,3DTRUS has a high clinical value in detecting prostatic lesions.
