The use of a new body stereotactic system to facilitate magnetic resonance (MR) guided biopsies is described. A skin entry point is first found using a localizer MR scan. The articulating arm of the stereotactic unit is then used to aim the MR needle at the entry point and accurately maintain the needle at the correct angle to intersect the target area. Complex angles may be used to allow needle passes outside the scan plane. This is accomplished by angling the arm out of the plane of the section.
描述了一种使用新型身体立体定向系统来辅助磁共振（MR）引导活检的方法。首先使用定位MR扫描找到皮肤进针点。然后使用立体定向装置的关节臂将MR针瞄准进针点，并精确地将针保持在正确角度以穿过目标区域。可使用复杂角度以使针在扫描平面外穿过。这是通过将臂倾斜到切片平面之外来实现的。
