摘要:
目的 评价压缩感知（CS）在高分辨率颅内血管壁成像（HR-MR VWI）中的临床应用价值。方法 回顾性分析2022年1月-2023年4月萨米医疗中心招募的14例健康志愿者及14例动脉粥样硬化患者（动脉粥样硬化斑块32个）的MRI检查影像资料，均接受了T1mx3d-uCS和T1mx3d-nonCS序列检查，对其血管壁图像质量进行盲法独立评分，分析T1mx3d-uCS和T1mx3d-nonCS序列图像质量、序列管径宽度及序列斑块性质。结果 与T1mx3d-nonCS相比，T1mx3d-uCS的扫描覆盖全脑+颈动脉分叉以上血管壁成像，扫描时间缩短；T1mx3d-nonCS和T1mx3d-uCS在不同血管分段的图像质量、清晰度及伪影评分比较，差异无统计学意义（P＞0.05）；T1mx3d-uCS序列扫描图像识别未出现漏诊情况；T1mx3d-nonCS和T1mx3d-uCS两组扫描序列对斑块狭窄程度分级和斑块强化分级检出率比较，差异无统计学意义（P＞0.05）。结论 与T1mx3d-nonCS相比，T1mx3d-uCS可实现高分辨率、各向同性、全脑+颈动脉分叉以上血管壁成像，图像质量可接受，不影响诊断性能，同时缩短扫描时间。
Abstract:
Objective To evaluate the clinical application value of compressed sensing (CS) in high resolution magnetic resonance vascular wall imaging (HR-MR VWI).Methods The MRI imaging data of 14 healthy volunteers and 14 patients with atherosclerosis (32 atherosclerotic plaques) recruited from Sami Medical Center from January 2022 to April 2023 were retrospectively analyzed. All patients underwent T1mx3d-uCS and T1mx3d-nonCS sequence examinations. The image quality of the vascular wall was scored independently by blind method, and the image quality, sequence diameter width and sequence plaque properties of T1mx3d-uCS and T1mx3d-nonCS sequences were analyzed.Results Compared with T1mx3d-nonCS, the scanning of T1mx3d-uCS covered the whole brain+carotid artery bifurcation, and the scanning time was shortened. There was no significant difference in image quality, clarity and artifact score between T1mx3d-nonCS and T1mx3d-uCS in different vascular segments (P>0.05). There was no missed diagnosis in T1mx3d-uCS sequence scanning image recognition. There was no significant difference in the detection rate of plaque stenosis grade and plaque enhancement grade between T1mx3d-nonCS and T1mx3d-uCS scanning sequences (P>0.05).Conclusion Compared with T1mx3d-nonCS, T1mx3d-uCS can achieve high resolution, isotropic, whole brain+carotid artery bifurcation vascular wall imaging, and the image quality is acceptable, which does not affect the diagnostic performance and shortens the scanning time.
