Digital subtraction angiography is considered the gold standard imaging technique for diagnosis and monitoring of pediatric peripheral vascular lesions since in addition to providing information regarding blood supply to the lesion, it also provides an option for therapeutic embolization. Unfortunately, this technique is an invasive procedure requiring induction of general anesthesia, iodinated contrast material, ionizing radiation exposure and small albeit definable risk of potentially life-threatening complications. Here, we evaluate the efficacy of time-resolved MRA for evaluation of suspected peripheral vascular lesions in infants and young children.
