ABSTRACT
Objective To investigate the CT angiography (CTA) in the diagnosis of intracranial atherosclerosis.Methods Sixty-eight cases of suspected ischemic cerebrovascular disease patients were enrolled in this study,and all patients underwent CTA.Parallel image post-processing was done.CTA characteristics were observed and compared with digital subtraction angiography (DSA) results.Results A total of 376 lesions in 68 cases were examined,112 lesions were found in CTA; intracranial atherosclerotic plaques mainly distributed in the internal carotid artery (53 lesions),anterior cerebral,middle and posterior artery (39 lesions) and vertebral-basilar artery (20 lesions).In narrow artery segment,stenosis with calcified plaque was in 32 lesions,mostly in the middle cerebral artery,the cavernous segment of the internal carotid artery,clinoids segment and intracranial vertebral artery.For non-calcified plaque,CTA showed fuzzy.DSA showed 128 total lesions,and severe stenosis rate in CTA [9.31% (35/376)] and DSA [9.31% (35/376)] was consistent.Thirty-eight patients were correctly diagnosed.Conclusions CTA as a minimally invasive intracranial atherosclerosis diagnostic methods,consumes less time with low cost and high spatial resolution.It is suitable for clinical universal application.
