MRA/MRV for diagnosing PE

In this multi-center trial of 371 patients with suspected PE, all had MRA/MRV, and the results were compared with the reference standard for diagnosing PE, including clinical assessment, Ddimer, VQ scanning, venous USG, and CTA/CTV. They found that technically adequate scans had good testing characteristics (sensitivity and specificity of 78% and 99% for MRA, and 92% and 96% for MRA/MRV) but inadequate scanning rates ranged from 11% to 52% at different centers. MRA/MRV has excellent testing characteristics, but only at centers where technically adequate scans can be routinely performed (abstract)
