CT评估肺磨玻璃结节进展及预后的研究现况

Current status of CT in evaluating the progression and prognosis of GGNs of the lung

近年来,随着医学影像技术的不断发展,肺磨玻璃结节(ground glass nodule,GGN)的检出率逐年升高,并受到广泛关注。GGN不仅可见于良性疾病,也是肺腺癌的早期表现。与实性结节相比,GGN影像学表现形式多样,发展变化快慢不一,导致临床治疗的争议较大。该文基于不同的CT影像学检查方法评估肺GGN良恶性进展及预后,总结肺GGN在影像学方面的恶性进展预测,有助于临床医师在患者肺GGN筛查、随访、后期治疗中做出准确的判断。

In recent years,with the continuous development of medical imaging technology,the detection rate of ground glass nodules(GGNs)has increased year by year,and has been widely concerned.GGNs are not only seen in benign diseases,but also are early manifestation of lung adenocarcinoma.Compared with solid nodules,GGNs have a variety of imaging manifestations and a different pace of development,which leads to a great controversy in clinical treatment.This paper evaluates the benign and malignant progression and prognosis of GGNs of the lung based on different CT imaging methods,and summarizes the malignant progression prediction of GGNs of the lung in imaging aspects,which is helpful for clinicians to make accurate judgments in the screening,follow-up,and later treatment of GGNs of the lung.
