摘　　要：目的探讨肺原位腺癌的临床和能谱CT低剂量扫描的影像学表现。方法回顾分析近3年来该院经手术病理证实的肺原位腺癌28例患者的资料，所有患者均行能谱CT低剂量扫描。结果CT表现为混合磨玻璃结节影15例，磨玻璃结节影9例，实性结节影2例，模糊小斑片状密度增高阴影2例；病灶最大径均小于30mm，其中最大径10-20mm22例。结节边缘模糊26例、清楚2例，分叶、毛刺20例，病灶内密度不均匀26例。均匀2例，可见局部支气管充气征15例。所有病例无一例发现远处或淋巴结转移。结论肺原位腺癌CT多表现为磨玻璃或混合磨玻璃结节影，小部分为实性结节影及小斑片状稍高密度影。能谱CT低剂量扫描能清晰地显示肺原位腺癌的影像学特征，对肺原位腺癌诊断具有重要的临床价值。Objective To discuss the imaging performance of puhaonary adenocarcinoma in situ by clinical and energy spectrum CT low-dose scanning. Methods 28 patients with pulmonary adenocarcinoma in situ confirmed by surgery and pathology in recent 3 years were reviewed and all patients were given energy spectrum CT low-dose scanning. Results 15 cases were mixed ground-glass nodular shadow, 9 were ground-glass nodular shadow, 2 were solid nodular shadow, and 2 were blurred small patched increased density shadow. The largest diameters of foci were all below 30 ram, of which 22 cases were 10-20 mm. The edges of nodules were blurred in 26 cases, and clear in 2 cases. 20 cases had leaflets and burrs. The inner density was uneven in 26 cases, and even in 2 cases. 15 cases were observed with local air bronchogram. No distal or lymphatic metastasis was observed. Conclusion Pulmonary adenocarcinoma in situ is commonly presented as ground-glass or mixed ground-glass nodular Shadow, and fewer cases are presented as solid nodular shadow and small patched increased density shadow. Energy spectrum CT low-dose scanning can clearly show the imaging features of pulmonary adenocarcinoma in situ, and has high clinical value in diagnosis of pulmonary adenocarcinoma in situ.
