The study by Anderson and colleagues1 in this issue of JAMA convincingly demonstrates that computed tomographic pulmonary angiography (CTPA) is not inferior to ventilation-perfusion (/) lung scanning for the exclusion of pulmonary embolism (PE). Confirmation on this point is comforting because CTPA has had a wide range of sensitivities reported for detection of PE2 but nevertheless has largely supplanted /scanning for several years for this purpose.3
