We describe a simple, practical technique for producing elastography images of the prostate. Our standard technique for the detection of prostatic cancer is ultrasound guided systematic biopsy of the prostate, with extra targeted biopsies of any abnormal areas detected by grey-scale ultrasound. The aim of this study to determine whether adding elastography imaging with targeted biopsies of abnormal areas detects more cancers. The results of elastography imaging were evaluated against grey-scale images and biopsy data in 100 patients. Elastography detected an additional 5 cancers in the 100 patients and detected an extra 3 patients with cancer at the expense of 8 extra biopsies. This represents a significant improvement in the detection rate of prostatic cancer.
我们描述了一种用于生成前列腺弹性成像图像的简单实用技术。我们检测前列腺癌的标准技术是超声引导下的前列腺系统活检，并对灰阶超声检测到的任何异常区域进行额外的靶向活检。本研究的目的是确定在对异常区域进行靶向活检时增加弹性成像是否能检测到更多癌症。在100名患者中，根据灰阶图像和活检数据对弹性成像的结果进行了评估。弹性成像在这100名患者中又检测出5例癌症，并且以额外8次活检为代价多检测出3例癌症患者。这代表着前列腺癌检测率有显著提高。
