Adenocarcinoma is the most common pathological type of peripheral lung cancer. However, even in patients with tumors of ≤ 3 cm in diameter, the postoperative prognosis varies, with poorly differentiated adenocarcinoma demonstrating a poor prognosis. Therefore, the use of preoperative imaging to determine tumor invasiveness is important, as limited resection (pulmonary segmentation or wide wedge resection) is currently recommended for non-invasive tumors [1-4]. Well-differentiated lung adenocarcinomas are often of a subsolid type, generally indicating a non-invasive nature and a good prognosis. These tumors may show ground-glass opacity on thin-section computed tomography (TSCT). On the other hand, poorly differentiated adeno
