The performance of percutaneous echoguided biopsy in the tumoral diagnosis is limited by several factors, among which tumor characteristics such as tumor type, size and location play an important role. With all the advantages offered by the ultrasound guidance, the overall sensitivity of this method in the tumoral diagnosis of tumor has remained around 90%. Contrast enhanced ultrasound guided percutaneous biopsy is a new developed technique aimed to increase the acurracy of percutaneous biopsies. With new ultrasound devices with split-screen mode, which displays both the CEUS and background B-mode US image simultaneously, on a single monitor, the procedure is technically feasible. CEUS guided percutaneous biopsy should be applied in large tumors with consistent necrosis, in hypovascular tumors or in those invisible or poorly visible to conventional ultrasound. The increased accuracy was demonstrated in liver tumors and in prostate adenocarcinoma.
经皮超声引导活检在肿瘤诊断中的性能受到多种因素的限制，其中肿瘤特征如肿瘤类型、大小和位置起着重要作用。尽管超声引导具有诸多优势，但该方法在肿瘤诊断中的总体敏感性仍维持在90%左右。超声造影引导下经皮活检是一项旨在提高经皮活检准确性的新技术。借助具有分屏模式的新型超声设备，可在单个监视器上同时显示超声造影和背景B超图像，该操作在技术上是可行的。超声造影引导下经皮活检应应用于具有一致性坏死的大肿瘤、乏血供肿瘤或那些对传统超声不可见或显示不佳的肿瘤。在肝肿瘤和前列腺腺癌中已证实其准确性有所提高。
