[Abstract] Objective: To investigate the relationship between perfusion MRI and the changes of small vessels around the infarction.Materials and Methods: Twenty-nine patients with ischemic infarction of unilateral hemicerebrum underwent T1WI, T2WI, 3D SWAN and DSC-PWI. Among these patients, 10 had follow-up MR scan after treatment. There were 39 person-time MR scans in total. Compared the changes of small vessels on 3D SWAN with the perfusion manifestation on DSC-PWI and analyze the relationship between them.Results: In the 39 cases, there were more, thick and black small vessels of 26 cases on 3D SWAN. Among them, 23 cases had hyperperfusion (19 collateral circulation, 3 reperfusion, 3 hyperperfusion and 1 hypoperfusion) on perfusion MRI; There were less, thin and light vessels of 13 cases. Among these 13 cases, 9 were hypoperfusion, 3 had collateral circulation and 1 was reperfusion. None of them was hyperperfusion. With chi square test, there was a significant difference between the small vessels change and the perfusion manifestation around the infarction lesion (P<0.05).Conclusion: The small vessels change around the infarction lesion indirectly reflect the perfusion manifestation, the small vessels become more, thick and black correlated with hyperperfusion, and the small vessels turned less, thin and light correlated with hypoperfusion.
