【Abstract】 With the wide application of computed tomography(CT)in lung cancer screening,the discovery rate of solitary pulmonary nodules is significantly higher than before,but its benign and malignant identification and invasiveness evaluation are still hot and difficult topic in chest imaging research in recent years.Radiomics can extract and analyze a large number of high-level and quantitative imaging features from medical image images,which is of great value for qualitative diagnosis,staging,prognosis prediction and therapeutic evaluation of diseases.This article introduces the traditional CT features of solitary pulmonary nodules and the basic flow of radiomics,then reviews the research progress of radiomics in the benign and malignant identification and invasiveness evaluation of solitary pulmonary nodules.

隨著計(jì)算機(jī)斷層掃描(computed tomography,CT),尤其是低劑量CT在肺癌篩查中的廣泛應(yīng)用,孤立性肺結(jié)節(jié)(solitary pulmonary nodules,SPN)的發(fā)現(xiàn)率較以往顯著上升[1],通過基于CT的影像組學(xué)技術(shù)對(duì)孤立性肺結(jié)節(jié)進(jìn)行診斷和評(píng)估已成為國(guó)內(nèi)外研究的熱點(diǎn)。影像組學(xué)(radiomics)是指從醫(yī)學(xué)影像圖像中高通量地提取并分析大量高級(jí)且定量的影像學(xué)特征,對(duì)疾病的良惡性定性診斷、分期、預(yù)后預(yù)測(cè)、療效評(píng)價(jià)等具有重要價(jià)值[2]。本文基于CT的影像組學(xué)在孤立性肺結(jié)節(jié)中的研究進(jìn)展進(jìn)行綜述。
1 孤立性肺結(jié)節(jié)的定義及其影像檢查方法
根據(jù)Fleischner學(xué)會(huì)的定義[3],孤立性肺結(jié)節(jié)是指X線片或CT片上肺實(shí)質(zhì)內(nèi)單發(fā)、圓形或類圓形、邊界清晰或不清晰、直徑≤3 cm的不透明病灶,不伴有肺不張、衛(wèi)星病灶、肺門或縱隔淋巴結(jié)腫大及胸腔積液。SPN的病理類型主要包括肺部腫瘤性病變(惡性腫瘤、良性腫瘤)、感染性病變、非感染性病變、先天性疾病等。……
