MIP (A) of a patient with diffuse large cell B lymphoma in complete metabolic response showing multiple pulmonary uptakes also visible in the axial PET slice (B) and corresponding to ground glass opacities in the axial CT (C) and PET/CT slices (D).

Case 2. MIP (A) of patient followed for melanoma showing intense pulmonary and hilar mediastinal uptake corresponding to bilateral ground glass opacities of peripheral predominance and mediastinal and hilar adenopathies visible in the PET (B), CT (C) and PET/CT tomographic slices (D).
