Invasive angiography is regarded as the golden standard for basilar artery imaging and for defining pathological features with radiological methods. The dolichoectasia of basilar artery can be diagnosed with comparable confidence by both MRA and CTA. It is also known that both contrast enhanced CT and MRI studies provide important information in diagnosing basilar artery dolichoectasia; however, only a few studies about the compatibility of the diameters measured with MRI versus TOF MRA are present. In this study, we compared the diameters measured with MRI to the ones measured with TOF MRA. We found that the two measurements are correlated, though the measurement taken with T2 weighted images were not as statistically significant as the ones taken with TOF MRA. As a result, we reached the following conclusions that will assist physicians with patients that are diagnosed with basilar artery dolichoectasia: (1) when following up a with MRI, the results of above comparison should be taken into consideration, and (2) when studying the pathological and anatomical variation of basilar artery, reporting physician should ensure detailed analysis of data. Present study will help clinicians in diagnosis, treatment, and follow up of patients with basilar artery dolichoectasia.
