The nature of opaque lesions such as effusions, atelectasis, masses, and consolidations can be clarified by sonography. This study investigated the sensitivity and accuracy of ultrasound-guided percutaneous core needle biopsy in different thoracic tumors (lung, pleural, chest wall, and mediastinal). Sixty patients underwent ultrasound-guided percutaneous transthoracic core biopsy of peripheral thoracic masses with a Tru-Cut needle with a big bore. Twenty masses were in the lung, seventeen lesions were in the pleura, ten masses were in the mediastinum, eleven were enlarged palpable lymph nodes, and two masses were in chest wall. The sensitivity, PPV, and accuracy for detection of chest tumors in the chest wall, mediastinum, lung, and pleura were 100% for all, and in LN 88.9, 100, and 90.9%, respectively. The overall diagnostic performance of sonar-guided Tru-Cut needle biopsy in diagnosis was 97.78% sensitivity, 98.18% accuracy, and 100% PPV. Tru-Cut needle percutaneous transthoracic core biopsy is a convenient and sensitive process in obtaining samples under ultrasound guidance for exact histological diagnosis of thoracic tumors. The diagnostic efficiency is high, and the technique can also be used in outpatients, which is relatively simple. NCT, NCT04741958 Registered 5 February 2021, retrospectively registered,

超声引导下经胸Tru-Cut核心活检在诊断周围胸廓病变中的作用

不透明病变的性质，例如积液、肺不张、肿块和实变，可以通过超声检查来明确。本研究调查了超声引导下经皮空心针活检在不同胸部肿瘤（肺、胸膜、胸壁和纵隔）中的敏感性和准确性。60 名患者接受了超声引导下经皮穿刺活检，使用大孔 Tru-Cut 针对周围胸部肿块进行了穿刺活检。肺20个肿块，胸膜17个肿块，纵隔10个肿块，可触及淋巴结肿大11个，胸壁2个肿块。检测胸壁、纵隔、肺和胸膜中的胸部肿瘤的灵敏度、PPV 和准确度均为 100%，LN 分别为 88.9、100 和 90.9%。声纳引导的 Tru-Cut 穿刺活检在诊断中的总体诊断性能为 97.78% 的灵敏度、98.18% 的准确度和 100% 的 PPV。Tru-Cut 针经皮经胸核心活检是在超声引导下获取样本以准确组织学诊断胸部肿瘤的一种方便且灵敏的过程。诊断效率高，该技术也可用于门诊，相对简单。NCT, NCT04741958 2021 年 2 月 5 日注册，追溯注册，该技术也可用于门诊，相对简单。NCT, NCT04741958 2021 年 2 月 5 日注册，追溯注册，该技术也可用于门诊，相对简单。NCT, NCT04741958 2021 年 2 月 5 日注册，追溯注册，
