Dynamic contrast-enhanced MR angiography and MR imaging of the carotid artery: high-resolution sequences in different acquisition planes

S Aoki, H Nakajima, H Kumagai, T Araki
2000 American Journal of Neuroradiology  
We evaluated the clinical utility of performing 3D contrast-enhanced MR angiography in the axial plane immediately after performing angiography in the coronal plane.  ...  Coronal 3D MR angiography was performed after administering a bolus injection of contrast material (20 mL) with automatic triggering. This was immediately followed by an axial acquisition.  ...  Twenty carotid arteries of 33 patients who had both contrast-enhanced MR angiography and X-ray DSA showed more than 0% stenosis by NASCET criteria and were used for this analysis.  ...

2018 arXiv   pre-print
A new similarity measure is also introduced for the comparison of the source and target images during image registration.  ...  It will result in a cheaper, faster and more accessible evaluation of the acute phase of the stroke overcoming the current limitations of the proposed systems in the state-of-the-art.  ...  In particular, the patient is exposed to an x-rays beam. The projected image is captured on a semicircular x-ray detector. The patient is po- sitioned between the x-ray source and the detector.  ...
