摘要
孤立性肺结节(SPN)是指肺部直径≤3cm近乎圆形的病变,其主要由肺实质包绕,患者无肺不张与肺门扩大及胸腔积液等表现。影像学检查是排查SPN及良、恶性诊断的主要手段,其对该病的诊断已从单纯形态检查向功能学与分子学检查发展。良性结节一般处于疾病早期,若发现及时,不仅能够提升临床治疗效果,对患者生活质量及生存时间亦具有重要意义。本文就影像学检查对SPN的良、恶性鉴别的研究进行综述,以期为该病的诊断提供参考。
Solitary pulmonary nodule(SPN)is a nearly circular lesion with a diameter of≤3 cm in the lung,which is mainly surrounded by the lung parenchyma,and the patients do not present with atelectasis,hilar enlargement or pleural effusion.Imaging is the main tool to detect benign and malignant SPN,and the diagnosis of this disease has evolved from pure morphological examination to functional and molecular examination.Benign nodules are usually formed in the early stage of the disease,and if detected in time,they can not only improve the clinical treatment effect,but also have important significance for the quality of life and survival time of patients.In this paper,we review the study on the differentiation of benign and malignant SPN by imaging examination,with the aim of providing a reference for the diagnosis of this disease.
