Fig. 2. Triple-rule-out scan using wide-volume scan method in 40-year-old woman diagnosed with acute pulmonary arterial thromboembolism.

A. Detector width is set at 14–16 cm to cover half of entire thorax, and whole chest is covered with two axial volume scan acquisitions. B. Whole-chest CT scan acquired using two axial volume scans that are automatically stitched immediately after reconstruction. C. Data from second scan are separately reconstructed for coronary angiography. Multifocal low-density filling defects in both lobar and segmental pulmonary arteries suggesting pulmonary arterial thromboembolism (arrows in B). No definite abnormality is observed in thoracic aorta and coronary arteries. RCA = right coronary artery
