[MR venography using 3D-fast STIR sequence for lower extremities].
Venography of the lower extremities performed by injecting iodinated contrast material requires a complicated technique. Veins of lower-flow-speed such as varices are scarcely outlined by using the time-of-flight MR angiography technique. On the other hand, the 2D fast SE technique has proven itself unsuccessful when used with medium magnetic field MRI equipment in which a very long TR is unavailable. We obtained images of lower extremity veins by using the 3D fast STIR technique and medium magnetic field MRI equipment of 0.5 Tesla. The results were crisp angiographic images of lower-flow-speed veins including varices.
