Chest Radiographic and High-resolution CT Findings of the Patients.

Patient	Chest radiographic findings	Chest high-resolution CT findings
1	Normal findings	Multiple nodules with a halo of ground-glass opacity or without a halo. The nodule size ranges from 5 to 10 mm.
		The lesions are distributed in the subpleural area.
2	Irregularly marginated ground-glass nodule	Multiple nodules or nodular ground-glass opacities that range in size from 5 to 15 mm.
		The lesions are distributed in the subpleural area.
3	Ill-defined ground-glass nodule	Solitary nodular ground-glass opacity with ill-defined margins up to 18 mm in size.
		The lesions are distributed in the subpleural area.
4	Normal findings	Multiple ground-glass opacities with ill-defined margins that range in size from 3 to 5 mm.
		The lesions are distributed in the subpleural area.
5	Ground-glass opacity in the lower lung field	Non-segmental crazy-paving appearance in the right middle and lower lobe.
		The lesions are distributed in both central and subpleural areas of the lung.
6	Normal findings	Multiple nodules without a halo. The nodule size ranges from 10 to 15 mm.
		The nodules are distributed in the subpleural area.
7	Normal findings	Multiple irregularly marginated nodules with a halo of ground-glass opacity.
		The nodule size ranges from 3 to 20 mm. The nodules are distributed in both central and peripheral areas of the lung.
