Coronal MRDTI images from 3 study patients. (A) MRDTI negative for DVT with symmetric low signal intensity in both popliteal veins, despite an incompressible popliteal vein in the left leg upon CUS. (B) Asymmetrical high signal intensity in the left popliteal vein diagnostic of acute recurrent DVT of the left leg (arrow). (C) Asymmetrical high signal intensity in the right great saphenous vein diagnostic for acute thrombophlebitis, but not DVT, in the right leg (arrow).
