摘　　要：目的探讨高分辨率磁共振血管壁成像(HR-VWI)评价颅内未破裂动脉瘤(UIA)的作用。方法连续收集2018-01—2021-01昆明医科大学附属延安医院、昆明市第二人民医院就诊的UIA患者82例,经过HR-VWI成像,观察动脉瘤位置、大小、SR值(最大瘤体瘤深与近端载瘤动脉直径的比值)及测量信号强度。结果UIA位于大脑前动脉5例,中动脉22例,后动脉1例,前交通20例,后交通6例,颅内颈内动脉33例,椎动脉2例;其中两处以上多发动脉瘤患者4例,病灶大小2~38(6±5.17)mm;45例存在动脉瘤壁强化的现象,37例瘤壁未见强化。结论HR-VWI判断UIA的形态、SR值及信号强化可以客观反映动脉瘤的稳定性,能够提供一定的诊治依据,已成为常规检查。Objective To study the high-resolution magnetic resonance imaging of the vessel wall(HR-VWI)in the evaluation of the application of the unruptured intracranial aneurysms(UIA).Methods Totally 82 UIA patients were continuously collected from January 2018 to January 2021 at Yan.an Hospital Affiliated With Kunming Medical University and the Second People.s Hospital of Kunming,and HR-VWI imaging was used to observe the location,size,SR value(the ratio of the depth of the largest aneurysm to the diameter of the near-end carrier aneurysm)and the measurement of signal strength.Results UIA was located in 5 cases of pre-brain artery,22 cases of medium artery,1 case of rear artery,6 cases of post-traffic,33 cases of intracranial cervical artery,2 cases of vertebral aneurysm,including 4 cases of multiple aneurysms in more than two places,the lesion size was 2-38(6±5.17)mm,45 cases of aneurysm wall strengthening phenomenon,37 cases of tumor wall did not see strengthening.Conclusion HR-VWI can objectively respond to the stability of UIA.s morphology,SR value and signal reinforcement,and can provide a certain basis for diagnosis and treatment,which has become a routine examination.
