影像学检查在病灶定位方面占有优势，是胸部病变的主要检查方法之一。然而，由于大多数病灶的影像学表现缺乏特异性，依靠影像学表现作定性诊断有时会相当困难。在ＣＴ导引下直接穿刺病灶，做病理学或细胞学诊断，可弥补影像学检查的不足。我们收集了我院１９９４年３月至１９ Imaging examination has advantages in lesion location and is one of the main examination methods for thoracic lesions. However, due to the lack of specific imaging features of most lesions, qualitative diagnosis based on imaging findings can sometimes be quite difficult. Direct puncture of lesions under CT guidance for pathological or cytological diagnosis can compensate for the lack of imaging. We collected our hospital from March to 19, 1994
