MR venography

MR venography has successfully shown its potential to evaluate DVT, central venous pathology, and anatomic variants such as venous malformations with high accuracy and has become a supplementary imaging technique to conventional venography, duplex sonography, and CT. Technical limitations, high cost, limited availability, and logical constraints still prevent widespread clinical use, however. As MR technology further improves and becomes more readily available, the role of MR venography in evaluating thromboembolic disease will probably expand. New contrast agents are likely to further improve the technique.
