Fig. 1

Arterial-phase MRA (A), delayed-phase MRA (B) and corresponding CT (C). The central signal dropout in the lateral basilar segmental pulmonary artery (arrow) corresponded to a true pulmonary embolus as confirmed by CT. Central signal dropout was 78% at arterial-phase and 79% at delayed-phase MRA. The adjacent posterior basilar segmental pulmonary artery (and adjacent pulmonary vein) show truncation artifact as confirmed by CT with a 24% and 23% signal dropout at arterial-phase and delayed-phase MRA, respectively (arrowheads).
