2021 Frontiers in Physiology  
However, the density resolution of TOF-MRA for the carotid plaque and carotid artery was not as good as that of CTA.  ...  The results show that there is a large deviation between the TOF-MRA and CTA 3D model of plaque in the carotid artery due to the unclear recognition of plaque boundary during 3D reconstruction, and this  ...  In the current carotid plaque examination method, both CTA and MR can judge the degree of lumen stenosis. But the effect of CTA on the carotid atherosclerotic plaque was better than MR.  ...

Aetiologies of internal carotid artery pseudo-occlusions in acute stroke patients: what neurointerventionalists can expect

Süha Akpınar, Pınar Gelener, Güliz Yilmaz
2017 British Journal of Radiology  
In cases of acute stroke, differentiation between an occluded and a patent internal carotid artery (ICA) is crucial for diagnosis and management.  ...  Although CT angiography (CTA) can be highly accurate in defining high-grade stenosis and ICA occlusions, misleading ICA occlusion patterns are not rare in patients with acute stroke.  ...  These are thought to occur because occlusion at different segments of the ICA results in arrested blood flow that inhibits contrast propagation and lumen filling in CTA imaging. 6 The aetiologic reasons  ...
