【摘要】：目的:研究孤立性肺結(jié)節(jié)(SPN)與周?chē)芎椭夤艿年P(guān)系,結(jié)合SPN的三維CT成像,以期提高對(duì)肺結(jié)節(jié)的良惡性診斷準(zhǔn)確率。方法:對(duì)經(jīng)手術(shù)和病理證實(shí)的26例SPN(其中惡性結(jié)節(jié)18例,良性結(jié)節(jié)8例,病灶直徑(3.7~31.4mm,平均11.8mm)進(jìn)行回顧性分析,所有患者做肺部CT常規(guī)5mm加局部薄層(1.25mm)重建,觀察病灶及周?chē)芎蜌夤苄螒B(tài)并進(jìn)行分類(lèi),經(jīng)工作站多平面重建(MPR)和曲面重建(CPR)及SPN三維重建軟件nodule assessment構(gòu)成空間三維形態(tài)。將分析結(jié)果與手術(shù)病理對(duì)照。結(jié)果:手術(shù)病理證實(shí)良性8例(35.71%),惡性18例(64.29%)。SPN-血管關(guān)系分為6型:Ⅰ型,斜形方向血管在病灶邊緣截?cái)?末端杵狀增粗。Ⅱ型,血管在病灶邊緣截?cái)?筆直走行,末端不呈杵狀增粗。Ⅲ型,血管進(jìn)入結(jié)節(jié)切跡處。Ⅳ型,一支血管穿過(guò)結(jié)節(jié)。Ⅴ型,血管受壓呈弧形改變,血管緊貼結(jié)節(jié)邊緣走行。Ⅵ型,為混合型。SPN-氣管關(guān)系分為6型:Ⅰ型,支氣管在SPN邊緣中斷;Ⅱ型,支氣管進(jìn)入SPN后中斷;Ⅲ型,支氣管穿過(guò)SPN;Ⅳ型,支氣管緊貼SPN邊緣走行;Ⅴ型,多支支氣管向SPN匯聚;Ⅵ型,為混合型。其次,SPN三維重建nodule assessment對(duì)SPN形態(tài)及SPN與肺血管和胸壁的關(guān)系顯示更直觀,三維CT重建均見(jiàn)肺血管供應(yīng)癥。結(jié)論:多層螺旋CT薄層掃描能清楚顯示SPN與肺血管和支氣管的關(guān)系,兩者對(duì)SPN良惡性性質(zhì)的診斷和鑒別診斷有重要價(jià)值。SPN三維CT重建技術(shù),更能直觀反映結(jié)節(jié)的形態(tài)學(xué)特征。
[Abstract]:Objective: to study the relationship between solitary pulmonary nodule (SPN) and peripheral blood vessels and bronchi, and to study the relationship between SPNs and SPN. Methods: 26 cases of SPNs proved by operation and pathology were analyzed retrospectively, including 18 cases of malignant nodules, 8 cases of benign nodules, and 3.7 mm of lesion diameter (mean 11.8 mm). All the patients were reconstructed by conventional 5mm and local thin layer (1.25mm). The lesions and their peripheral blood vessels and trachea were observed and classified. SPN 3D reconstruction software nodule assessment and workstation multiplanar reconstruction (MPR) and curved surface reconstruction software (nodule assessment) were used to construct spatial 3D morphology. The results were compared with those of surgery and pathology. Results: 8 cases of benign and 18 cases of malignant were proved benign by operation and pathology, and 18 cases were malignant. SPN- vascularization. The system is divided into 6 types: type 鈪，
