Clinical History: [ ]
Technique:
CT angio of the neck: Following rapid IV bolus of contrast material, rapid helical imaging with very thin slices from the aortic arch to the lower cranial level was performed. Following this, 3-D workstation was utilized to create 3-D rendered and MIP images. NASCET methodology was employed to evaluate the degree of stenosis.
CT angiography of the head: Following rapid injection of intravenous contrast material after an appropriate delay, very thin helical axial slices were obtained through the entire head. Following this, 3-D workstation was employed to create 3-D rendered and MIP images.
Contrast Dose: [ ] milliliters OMNIPAQUE [ ] concentration, INTRAVENOUS
Comparison: [ ]
Findings:
CT angio of the neck: There is no evidence of [greater than 30%] stenosis or occlusion of the right or left carotid and vertebral arteries.
CT angiography of the head: There is no evidence of aneurysm, AVM or vascular occlusive disease.
Impression:
CT angio of the neck: [No significant abnormality noted.]
CT angiography of the head: [Normal study.]
