PDFAbstract
Objective To evaluate the clinical value of low dose contrast agent CT angiography (CTA)in the diagnosis of head and neck vascular diseases. Methods A total of 75 patients who were suspected of head and neck vascular disease accepted head and neck CTA examination by low dose contrast agent. The imaging quality and the effect of lesion display were analyzed. Results The quality of all images met the diagnostic requirements. The excellent rate of images quality of carotid artery and cerebral arteries were 82.6% and 81.3% respectively. The results included 32 cases of aneurysms, 2 cases of vascular malformation, 13 cases of cerebral arteriosclerosis, 3 cases of carotid obstruction, and 2 cases of moyamoya. Conclusion The 128-slice spiral CT imaging of head and neck vessels with low-dose contrast agent can obtain the image quality that meets the diagnostic requirements, and reduce the dosage of contrast agent without affecting the diagnostic results effectively, which is conducive to reducing the possibility of adverse reactions of contrast agent.
