三维超声在膀胱疾病中的应用

目的 评估三维超声诊断膀胱疾病的临床价值。方法 采用Voluson530-D型超声诊断仪检查21例膀胱疾病患者，先用二维超声对膀胱病变进行观察。再用三维超声确定重建区，作三维重建分析。结果 21例膀胱疾病的三维图像立体感强，形态逼真，定位准确，病变内部结构、膀胱壁浸润及周围转移情况显像清晰。结论 三维超声能清晰地显示膀胱疾病的形态特点和内部结构。为诊断膀胱疾病提供可靠的信息。

Application of 3-D ultrasound in bladder diseases

Objective To evaluate the clinical application of 3 D ultrasound in the diagnosis of bladder diseases. Methods In 21 patients with bladder disease,3 D images were studied with a Voluson 530D diagnostic system.At first,the two dimensional images of lesions were collected,then defined 3 D volumes of interest were stored,reconstructed and analyzed. Results 3 D ultrasound provided a clear stereoscopic view and depicted the appearance of the 21 bladder diseases,displayed the internal structures,and showed invasive depth within and outside the bladder wall and also metastasis of the adjacent organs. Conclusions 3 D ultrasound can clearly demonstrate the morphologic characteristics and internal structures of the bladder disease and provide much more reliable information for the diagnosis of diseases.
