Imaging Findings of Acute Infarction Caused by Basilar Artery Occlusion

  • Objective: To investigate the imaging features of acute infarction caused by basilar artery occlusion (BAO). Methods: The data of 26 patients with acute infarction caused by BAO in our hospital from January 2016 to May 2018 were retrospectively analyzed. All patients underwent plain CT scan, noncontrast MRI scan and 3D-TOF MRA examinations. The plain CT images signs, MRI T1WI, T2WI and T2FLAIR signs at the occlusion displayed on the 3 D-TOF were mostly analyzed. Results: The BAO in this group was clearly shown by MRA. The acute infarction in the responsible blood supply area showed high signal on DWI and low signal on ADC. 18 cases showed high density artery sign and 6 cases showed calcification sign at the occlusion on CT images. T1WI showed 20 cases with hyper intense vascular sign at the occlusion as well as T2WI and FLAIR showed the absence of flow void phenomenon in all the 26 cases. Conclusion: BAO and its induced acute infarction can be diagnosed by MRA and MRI. CT and MRI imaging have a high display rate of basilar arterial vasculature signs and recognition of these signs is helpful for early diagnosis.
