MR Angiography as the Preferred Test for Pulmonary Embolism During the Iodinated Contrast Media Shortage of 2022: A Single-Center Experience

Caption

Patient was found to have deep vein thrombosis. Gadolinium-enhanced MRA was performed to assess for pulmonary embolus (PE). Coronal contrast-enhanced T1-weighted images in pulmonary arterial phase (A) and low flip-angle delayed phase (B) show PE (arrows, A and B). Delayed-phase image also shows cardiac chamber (star) and ascending thoracic aorta (chevron). Multiphase acquisition of MRA during inflow and outflow of contrast agent from pulmonary arteries is in distinction to single acquisition of CTA and may facilitate obtaining optimal enhancement of pulmonary arteries.
