Surgical excision biopsy is considered by many to be the "gold standard" for the diagnosis of breast lesions. Fine needle aspiration biopsy is used by some radiologists and other physicians in an attempt to diagnose breast lesions nonsurgically. To overcome the drawbacks associated with both of these methods, the author and his coworkers have developed the image-guided automated large-core breast biopsy method.
All biopsies are performed using either a dedicated, prone stereotactic device or high-resolution near-field ultrasound equipment for needle guidance. A "long-throw" (2.3 cm) automated core biopsy device fitted with a 14-gauge needle is used to acquire five or more core samples from each lesion for histologic evaluation.
The ability of percutaneous, image-guided, large-core breast biopsy to provide the correct histologic diagnosis of a breast lesion is equivalent to open surgical biopsy. The cost of large-core breast biopsy is one half to one quarter that of surgical biopsy. No adverse cosmesis or mammographic pseudolesion results.
In an era of increasing cost restraints in health care, it is important to identify means by which the level of patient care can be maintained or improved at lesser cost. Percutaneous large-core breast biopsy provides that opportunity in the diagnosis of breast disease and should prove to be a cost-effective, reliable, and expedient alternative to surgical biopsy.
许多人认为手术切除活检是诊断乳腺病变的“金标准”。一些放射科医生和其他医生使用细针穿刺活检试图非手术诊断乳腺病变。为克服这两种方法的缺点，作者及其同事开发了影像引导下的自动大芯针乳腺活检方法。
所有活检均使用专用的俯卧立体定位设备或高分辨率近场超声设备进行针引导。使用配备14号针的“长行程”（2.3厘米）自动芯针活检装置从每个病变获取五个或更多芯组织样本进行组织学评估。
经皮影像引导下的大芯针乳腺活检对乳腺病变进行正确组织学诊断的能力等同于开放手术活检。大芯针乳腺活检的成本是手术活检的二分之一到四分之一。未出现不良美容效果或乳腺X线摄影假病变。
在医疗保健成本限制不断增加的时代，确定以较低成本维持或改善患者护理水平的方法很重要。经皮大芯针乳腺活检在乳腺疾病诊断中提供了这样的机会，应被证明是一种经济有效、可靠且便捷的手术活检替代方法。
