背景：评估周围肺部病变和胸壁及纵隔病变的患者具有挑战性。通过成像研究鉴定的病变的性质可以通过活检的组织学评估来确定。在这个方向上的一个重要地方是胸外科医师在超声控制下使用切割针进行经胸活检（US-TTCNB）的日益普及。
BACKGROUND: Evaluation of patients with peripheral lung lesions and lesions of the chest wall and mediastinum is challenging. The nature of the lesion identified by imaging studies can be determined by histological evaluation of biopsies. An important place in this direction is the ever-increasing popularity among thoracic surgeons of the transthoracic biopsy with a cutting needle under ultrasound control (US-TTCNB).
