NSIP. Subpleural GGO in a posterobasal and subpleural location that could suggest dependent abnormalities and require another acquisition in prone position. However, the presence of a subtle GGO in subpleural lateral areas (arrows) precludes the need for an additional prone acquisition (a). A 3 mm-thick mIP slice increases our diagnostic confidence by reinforcing the visibility of abnormal densities (b). GGO, ground glass opacity; mIP, minimum intensity projection.
