Abstract/OtherAbstract:
|
Contrast-enhanced magnetic resonance angiography (CE-MRA) is a commonly used technique to assess the extracranial carotid arteries. We describe two patients (investigated for carotid artery atherosclerotic disease) who underwent CE-MRA. Results suggested pseudoaneurysms of the extracranial carotid arteries. Magnetic resonance direct thrombus imaging (MRDTI) showed that the appearances were due to intraplaque haemorrhage adjacent to the vessel, with the T1-shortening effect of methaemoglobin within the intraplaque haemorrhage mimicking blood flow on the CE-MRA sequence. The cases presented demonstrate this diagnostic pitfall and illustrate the contribution of simple magnetic resonance plaque imaging to establishing the correct diagnosis. |
