摘　　要：目的:优化颈颅联合高分辨血管壁MR检查成像序列,获得最佳空间分辨率、血管壁的锐利度和扫描时间。方法:回顾性分析2018年8月14日至2020年3月9日于深圳市第二人民医院128例行颈部和颅脑高分辨率检查的图像,评价颈部冠状位、颅脑矢状位两个高分辨序列扫描与颈颅联合高分辨血管壁MR扫描图像的质量。结果:颈颅联合高分辨血管壁MR扫描的斑块显示清晰度、血管壁锐利度、颅脑微血管显示数量及清晰度的综合评分均明显优于颈部冠状位、颅脑矢状位两个高分辨序列扫描,差异具有统计学意义(P<0.05)。相比于颈部冠状位、颅脑矢状位两个高分辨序列扫描,颈颅联合高分辨血管壁MR扫描的扫描时间明显更短,空间分辨率更优。结论:颈颅联合高分辨血管壁MR扫描可以作为颈部和颅脑血管壁高分辨扫描的常规检查序列,但需彩色多普勒超声排除颈动脉和椎动脉起始段斑块病变。Objective Optimized the sequence of the cervical cranial combined high-resolution vascular wall MR examination imaging to obtain the best spatial resolution,sharpness of vascular vessel wall and scanning time.Methods Retrospectively analyzed the images of 128 patients who underwent high-resolution vascular wall MR examination of the cervical and cranial at Shenzhen Second People’s Hospital from August 14,2018 to March 9,2020,to evaluate the image quality of the two high-resolution sequences of the cervical coronal and cranial sagittal and the cervical cranial combined high-resolution vascular wall MR examination imaging.Results the comprehensive scores of the clarity of plaque display,the sharpness of vascular wall,the number and clarity of cerebral microvascular display of the cervical cranial combined high-resolution vascular wall MR examination imaging were significantly better than that of cervical coronal and cranial sagittal examination imaging,The difference was statistically significant(P<0.05).Compared with the two high-resolution sequences scans of the cervical coronal and the cranial sagittal,the scanning time of the cervical cranial combined high-resolution vascular wall MR scan was significantly shorter and the spatial resolution was better.Conclusion The cervica cranial combined high-resolution vascular wall MR scanning can be used as a routine examination sequence for high-resolution scanning of cervical and cranial vascular walls,but color Doppler ultrasound is required to exclude carotid and vertebral artery plaque lesions.
