Laser/radiofrequency thermal ablation has generated renewed enthusiasm regarding imaging options for lower extremity varicose veins. Central to their success is the assumption that pre-operative evaluation, using Doppler sonography, provides a reliable anatomic and functional map of this complex, variable vascular system. Such time-consuming cartography (often in excess of 60 minutes) places considerable demands upon both the technician and patient. Failure of identification of even a single incompetent perforating vein may result in recurrent varicosities. We describe an innovative, rapid though morphologically and functionally informative dynamic MR technique capable of challenging sonography as the reference standard for pre-operative varicose vein imaging.
