Dynamic contrast-enhanced magnetic resonance angiography of vascular malformations in pediatric patients. Case report.

The authors report the first clinical use of 3-tesla dynamic contrast-enhanced magnetic resonance (MR) angiography for the diagnosis of a vascular malformation in a pediatric patient. The supply and drainage of an arteriovenous malformation were accurately demonstrated on MR angiography, which was performed without sedating the patient. This lesion was confirmed on catheter angiography, and definitive treatment via embolization was undertaken in a single session. The patient's therapeutic response will be followed with surveillance dynamic MR imaging.
