Magnetic resonance angiography in the evaluation of carotid stent patency.

摘要

As more endovascular interventions are being used in the carotid circulation, including carotid angioplasty and stenting, a reliable imaging modality is needed to follow the results. Currently, duplex ultrasonography, magnetic resonance angiography (MRA), and angiography are the main modalities used. This report presents a case of MRA and duplex ultrasonography providing drastically different images, presenting the clinician with an opportunity to evaluate the various imaging modalities that are used in evaluating carotid stent patency.
