Our initial experience with low dose contrast‐enhanced (LCE) peripheral MR venography (MRV) is presented. Five subjects were studied using three‐dimensional (3D) fast imaging with a steady‐state precession (FISP) sequence. A dose of 60 ml of gadopentetate dimeglumine diluted 1:20 was used. A tourniquet was applied during lower extremity MR venography. The venous anatomy was well depicted with the 3D LCE technique in all subjects. Compared to the two‐dimensional (2D) time‐of‐flight (TOF) technique, acquisition time of 3D LCE MRV was much shorter, images looked sharper, and more veins could be seen. It is not affected by in‐plane saturation and can be performed repeatedly because of the low dose of contrast. This technique holds promise for the detection of venous thrombosis and other disorders.
