From: COVID-19-induced vascular angiopathy: CTPA signs in critically ill patients other than acute pulmonary embolism and high-lung opacity scores

Fig. 4

A 72-year-old COVID-19 male patient with pulmonary vascular enlargement (PVE) on a background of borderline total opacity score (TOS): a Coronal lung window CTPA revealed bilateral basal pulmonary vascular dilatation (more on the left side with relatively increased opacity density) manifested by abnormally increased calibre within the pulmonary abnormal opacity as well as lack of tapering and extension till the pleural surface (blue and yellow squares). Bilateral upper lobar PVE is also noted within the pulmonary abnormal ground-glass opacity (more on the left side—brown square) compared to the nearby cranial vessels in (purple square) and contralateral same level vessels in (green square). Right apical PVE outside the abnormal opacity is also noted (red square). b Detailed artificial intelligence quantitative assessment revealed: TOS = 10/20 and volumetric percentage = 37.83%
