Abstract:
Objective To investigate the effectiveness of optimized flow sensitive black blood(FSBB)imaging in detecting the number of branches and measuring the depth of lenticulostriate arteries(LSAs)in patients with acute ischemic stroke.Methods The ima-ging and clinical data of 39 patients with acute ischemic stroke who underwent vascular recanalization under digital subtraction angi-ography(DSA)were prospectively collected.All patients received 3.0T MR FSBB imaging within 48-96 hours postoperatively.The number and depth of LSAs branches on the affected side were observed,measured and recorded by the post-processing workstations for both FSBB and DSA images.The difference and correlation of the number and average depth of LSAs branches detected by FSBB and DSA were analyzed.The consistency of the average depth of LSAs branches detected by FSBB and DSA was evaluated.Results There was no statistically significant difference in the number and depth of bilateral LSAs branches detected by FSBB and DSA(P＞0.05).FSBB and DSA showed strong positive correlations in detecting the number and depth of LSAs branches(r=0.786,0.704;P＜0.05).The number of average depth difference of bilateral LSAs branches detected by FSBB and DSA exceeded the limit of agreement(LoA)was 3,accounting for 4.92％(＜5％).Conclusion Optimized FSBB imaging can be used to assess the detection of the number and depth measurement of LSAs branches in patients with acute ischemic stroke,showing good consistency with DSA.It provides valua-ble imaging evidence for the morphological assessment of LSAs in clinical practice.
