Exact localization of the needle tip during CT-guided needle biopsy is important for accurate diagnosis. Using a phantom model we evaluated different methods for localization. The most reliable method was direct visualization of a distinct feature of the needle such as a notch near the needle tip. Visualization of a black shadowing artifact and review of adjacent CT images to the one used for needle tip placement were less reliable.
在CT引导下的针吸活检过程中，精确确定针尖位置对于准确诊断至关重要。我们使用一个体模模型评估了不同的定位方法。最可靠的方法是直接观察针的明显特征，如针尖附近的凹槽。观察黑色阴影伪影以及查看与用于放置针尖的CT图像相邻的CT图像可靠性较低。
