Abstract
Ultrasound imaging of the prostate is commonly used to assess the size of the gland and for needle placement during systematic biopsy. Ultrasound evaluation of prostate cancer is limited by difficulty in distinguishing benign from malignant tissue. Although Doppler techniques may provide some improvement in the detection of prostate cancer, targeted biopsy based on conventional ultrasound with Doppler is not sufficient to replace systematic biopsy. Contrast-enhanced ultrasound imaging techniques that employ microbubble contrast agents represent an innovative approach to imaging of the neovascularity associated with prostate cancer. This review describes the application of contrast-enhanced ultrasound to improve detection and assessment of prostate cancer.
摘要
前列腺超声成像通常用于评估腺体大小以及在系统活检期间进行针穿刺定位。前列腺癌的超声评估因难以区分良性组织和恶性组织而受到限制。尽管多普勒技术在前列腺癌检测方面可能会有所改进，但基于常规超声与多普勒的靶向活检不足以取代系统活检。采用微泡造影剂的超声造影成像技术是一种用于对与前列腺癌相关的新生血管进行成像的创新方法。本综述描述了超声造影在改善前列腺癌检测和评估方面的应用。
