What Does It Mean If My CT Scan Shows Resolution Of Previous Pulmonary Lesions But Mentions Residual Linear Atelectasis And Ground-glass Changes?

Taken from my last CT scan results (UK). Interval resolution of previously noted pulmonary lesions, for example a subpleural lesion anteriorly within the left upper lobe that demonstrates minor residual linear atelectasis, a paravertebral right lower lobe lesion now demonstrates temporary to focus of groundglass change.
