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. ...

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 ...

We aimed to examine the ability of RH-PAT and IMT to predict coronary computed tomography angiography (CTA) plaque burden in clinically healthy subjects. ...
