肺部结节性病变穿刺活检中辅助引导定位技术的临床运用新进展

肺结节是肺部常见病变，它的定性诊断一直是临床诊断的难点，近些年随着高分辨率螺旋计算机断层扫描（computer tomography, CT）、灌注成像、双源CT双能量技术及正电子发射计算机断层显像（positron emission tomography，PET/CT）的深入研究，肺结节的诊断与鉴别诊断明显提高，但仍有少部分病变诊断困难，尤其是良恶性的鉴别。肺结节性病变穿刺活检术是临床获得病理的常用方法，其成功的关键是辅助定位技术的选择，现对各种辅助引导定位技术的进展予以综述。

New progress in clinical application of auxiliary guided localization technology in puncture biopsy of pulmonary nodular lesions

Pulmonary nodule is a common lung disease, and its qualitative diagnosis has always been a difficult point in clinical diagnosis. In recent years, with the in-depth study of high-resolution spiral CT scan, perfusion imaging, dual-energy technology of dual-source CT and PET/CT functional imaging, the diagnosis and differential diagnosis of pulmonary nodules have improved significantly, but there are still a few lesions difficult to diagnose, especially the identification of benign and malignant pulmonary nodules. Pulmonary nodular lesion puncture biopsy is a common method for clinical pathology and the key to success is the selection of auxiliary positioning technology. The progress of various auxiliary guided positioning techniques is reviewed.
