Abstract
For years, magnetic resonance angiography (MRA) has been a leading imaging modality
in the assessment of venous disease involving the pelvis and lower extremities. Current
advancement in noncontrast MRA techniques enables imaging of a larger subset of patients
previously excluded due to allergy or renal insufficiency, allowing for preintervention
assessment and planning. In this article, the current status of MR venography, with
a focus on current advancements, will be presented. Protocols and parameters for MR
venographic imaging of the pelvis and lower extremities, including contrast and noncontrast
enhanced techniques, will be reviewed based on a recent literature review of applied
MR venographic techniques. Finally, several disease-specific entities, including pelvic
congestion and compression syndromes, will be discussed with a focus on imaging parameters
that may best characterize these disease processes and optimize anatomical planning
prior to intervention.
