Popis: Purpose To determine the morphological changes of intracranial arteries and whole-brain perfusion in undetermined isolated vertigo (UIV) patients using 320-detector row computed tomography (CT). Methods A total of 150 patients who underwent CT angiography (CTA) and CT perfusion (CTP) imaging were divided into UIV group and benign paroxysmal positional vertigo (BPPV) group. Sixty individuals with sex- and age-matched without vertigo and cerebral diseases served as the control. The morphological changes of intracranial arteries, perfusion parameters and vascular risk factors (VRFs) were analyzed, calculated and compared. Results In UIV patients, hypertension (HT), hyperlipidemia and number of VRFs ≥ 3 occurred more commonly (P
Highlights • UIV refers to undetermined IV. • The morphological changes of intracranial arteries and whole-brain perfusion are not clear in UIV patients. • 320-detector row CT system can evaluate the vascular information and perfusion regions of the whole-brain. • Unusual morphology of intracranial VBA and hypoperfusion should raise suspicion concerning the etiology in UIV patients with multiple VRFs.
