Needle biopsy has replaced excisional biopsy as a definitive diagnostic technique for breast tumours, although excisional biopsy is still used for complete tumour removal for therapeutic and/or diagnostic purposes. Many vacuum-assisted breast biopsy (VAB) systems have been made available by several manufacturers since the release of the Mammotome (MMT) by Johnson & Johnson in 1995. Several recent discussions have been conducted to identify whether core needle biopsy (CNB) or VAB, is more appropriate. However, currently available VAB systems differ from the conventional system (i.e. articulate arm type 11-gauge(G) MMT), and the characteristics of both CNB and VAB have been improved. In CNB, a 14-G needle is frequently used to obtain a larger sample. By contrast, VAB is considered easier to perform because it uses a thinner needle and a lighter, non-tethered system. When differentiating CNB from VAB, the type of VAB should also be defined. In this review, we discuss the characteristics of ultrasonography-guided VAB and CNB with a focus on practical issues such as the number of samples and volume of tissue obtained during ultrasonography-guided needle biopsy.
针吸活检已取代切除活检，成为乳腺肿瘤的确定性诊断技术，不过切除活检仍用于出于治疗和/或诊断目的的完整肿瘤切除。自1995年强生公司推出麦默通（MMT）以来，多家制造商已推出多种真空辅助乳腺活检（VAB）系统。最近进行了几次讨论，以确定粗针活检（CNB）还是VAB更合适。然而，目前可用的VAB系统与传统系统（即关节臂式11号（G）MMT）不同，并且CNB和VAB的特性都有所改进。在CNB中，经常使用14G针来获取更大的样本。相比之下，VAB被认为更容易操作，因为它使用更细的针和更轻便、无束缚的系统。在区分CNB和VAB时，也应定义VAB的类型。在本综述中，我们将重点讨论超声引导下VAB和CNB的特性，如超声引导下针吸活检期间获取的样本数量和组织体积等实际问题。
