CT三维重建示例。A：轴面；B：冠状面；C：矢状面；D：三维成像。病例来源：63岁老年男性患者，病灶位于右肺中叶，影像学表现为PSNs。重建后参数：肿瘤体积=1, 294 mm³，实性/磨玻璃成分体积=269 mm³/1, 025 mm³，实性/磨玻璃成分3Dm-CT=-5 Hu/-388 Hu，SUVmax=2.97，术后病理亚型为PPA。

CT 3D reconstruction example. A: axial plane; B: coronal plane; C: sagittal plane; D: 3D imaging. Case source: 63-years-old, male patient, PSNs in the right middle lobe. Parameters after reconstruction: tumor volume=1, 294 mm³, solid/ground glass component volume=269 mm³/1, 025 mm³, solid/ground glass component 3Dm-CT: -5 Hu/-388 Hu. SUVmax=2.97, the postoperative pathological subtype was PPA. PSNs: part-solid nodules; 3Dm-CT: 3-dimensional mean-CT value; SUVmax: maximal standard uptake value; PPA: papillary pattern-predominant adenocarcinoma.
