Demographic, baseline clinical, and radiological characteristics of patients with confirmed lung cancer (n=72)

*Breast cancer (n=1), colon cancer (n=1), thyroid papillary carcinoma (n=1), and uterine cervix cancer (n=2) were included.
IQR: interquartile range; FDG: fluoro-2-deoxy-D-glucose; PET/CT: positron emission tomography/computed tomography; FNA: fine needle aspiration; CT: computed tomography; MRI, magnetic resonance imaging.

*More than one stage was used in two patients with two GGN lesions, because SUVmax and the characteristics of GGN patterns differed between the two GGN lesions in these patients (one had both Ta1N0M0 and T1aN0M0, and the other had both T1aN0M0 and T1bN0M).
GGN: ground-glass nodule; IQR: interquartile range; SUVmax: maximum standardized uptake value; PET/CT: positron emission tomography/computed tomography; CT: computed tomography; MRI: magnetic resonance imaging.

*The final stage was determined by the pathological stage and additional diagnostic work-up to evaluate the abnormal findings which were detected on PET/CT scans. †More than one stage was used in two patients with two GGN lesions, because pathologic results and radiologic findings, such as SUVmax, and the characteristics of GGN patterns differed between the two GGN lesions in these patients (one had both Ta1N0M0 [minimally invasive adenocarcinoma, pure GGN, and SUVmax 0] and T1aN0M0 [invasive adenocarcinoma, part-solid GGN, and SUVmax 4.4], and the other had both T1aN0M0 [minimally invasive adenocarcinoma, part-sloid GGN, and SUVmax 3.9] and T1bN0M [adenocarcinoma in situ , pure GGN, and SUVmax 0]).
PET/CT: positron emission tomography/computed tomography; MRI: magnetic resonance imaging; GGN: ground-glass nodule; SUVmax: maximum standardized uptake value.

CT: computed tomography; PET/CT: positron emission tomography/computed tomography; B-MRI: brain magnetic resonance imaging; NA: not acquired.
