The authors used a gantry tilt of 20 degrees in five patients to allow fine-needle aspiration biopsy of peripheral pulmonary lesions that were difficult to approach with a vertical alignment because of overlying ribs. This method allowed a direct approach to the lesion in all five cases, with the entire needle path visible in the scanning plane, avoidance of vital structures, and traversal of a minimal amount of normal lung parenchyma.
作者对5例患者采用了20度的机架倾斜，以便对因上方肋骨而难以垂直进针的周围肺部病变进行细针穿刺活检。该方法在所有5例中都能直接到达病变部位，扫描平面上可见整个针道，避开了重要结构，且穿过的正常肺实质最少。
