From: Incidental finding of large pneumothorax on Cardiac MR scan
a Axial ‘black blood’ CMR slice at the level of the main pulmonary artery showing a large black space devoid of lung markings typical of a large pneumothorax of the left lung. b Anterior coronal ‘Black blood’ slice showing complete absence of lung parenchyma in the left anterior chest giving the impression of a much larger pneumothorax, note the absence of mediastinal shift. c Short axis stack showing compression of basal right ventricular free wall in diastole. d Plain PA chest X Ray showing 3 cm apical pneumothorax. The 2D appearance is much less dramatic than that of panel b
