Title
MR Angiography of the Neck
Clinical History
Patient-specific — populated from user input at report time. Shows "None" if not provided.
Comparison
No prior studies available for comparison.
Technique
Multi-slab noncontrast 2D time-of-flight MRA technique with 3D time-of-flight cone down views of carotid bifurcations. Multiple 3D MIP reconstructions performed. Qualitative analysis and quantitative measurements of proximal internal carotid arteries obtained with reference to distal cervical segments using NASCET criteria.
Findings
MR angiography of the neck demonstrates the cervical vasculature.
Right Common Carotid Artery:
The right common carotid artery origin is not visualized. The visualized segment demonstrates normal caliber without evidence of dissection, hemodynamically significant stenosis, or occlusion.
Right Carotid Bifurcation:
No significant stenosis at the right carotid bifurcation.
Right Internal Carotid Artery:
The right internal carotid artery demonstrates normal course and caliber. The visualized cervical segment is patent without significant stenosis.
Left Common Carotid Artery:
The left common carotid artery origin is not visualized. The visualized segment demonstrates normal caliber without evidence of dissection, hemodynamically significant stenosis, or occlusion.
Left Carotid Bifurcation:
No significant stenosis at the left carotid bifurcation.
Left Internal Carotid Artery:
The left internal carotid artery demonstrates normal course and caliber. The visualized cervical segment is patent without significant stenosis.
Right Vertebral Artery:
The right vertebral artery is visualized from its origin to the distal intradural segment without evidence of stenosis, dissection, or occlusion.
Right PICA Origin:
No aneurysm at the origin of the right PICA.
Left Vertebral Artery:
The left vertebral artery is visualized from its origin to the distal intradural segment without evidence of stenosis, dissection, or occlusion.
Left PICA Origin:
No aneurysm at the origin of the left PICA.
Vertebral Artery Dominance:
The vertebral arteries are codominant.
Horizontal Vertebral Artery Segments:
The horizontal segments of the vertebral arteries demonstrate loss of flow related signal on 2D time-of-flight images, likely secondary to in-plane flow signal saturation phenomena.
Vascular Displacement and Splaying:
No evidence of vascular displacement or splaying of the carotids bilaterally.
Impression
No evidence of vascular displacement, aneurysm, or hemodynamically significant stenosis of the cervical vasculature.
