Body and Extremity MR Venography: Technique, Clinical Applications, and Advances

Magnetic resonance venography (MRV) represents a distinct imaging approach that may be used to evaluate a wide spectrum of venous pathology. Despite duplex ultrasound and computed tomography venography representing the dominant imaging modalities in investigating suspected venous disease, MRV is increasingly used due to its lack of ionizing radiation, unique ability to be performed without administration of intravenous contrast, and recent technical improvements resulting in improved sensitivity, image quality, and faster acquisition times. In this review, the authors discuss commonly used body and extremity MRV techniques, different clinical applications, and future directions.
