Current value of the 4D CTA technique in screening for cranial vascular disease
With the rapid development of medical technology,4D CTA technology has become one of the important detection methods for intracranial disease screening.Compared with traditional CTA technology,it has higher temporal resolution and spatial resolution.Compared with intracranial digital silhouette angiography(DSA)technology,it has the advantage of minimally or non-invasively.4D CTA technology has been proven to improve the diagnostic rate of brain disease detection.This review will elaborate on the screening of stroke,diagnosis of arteriovenous malformations,examination of intracranial aneurysms,and the limitations and future development prospects of 4D CTA technology.
