摘 要:目的探讨移动式头颈MRI系统在神经外科的临床应用价值。方法南方医科大学珠江医院神经外科中心自2022年6月至9月应用移动式头颈MRI系统扫描213例颅脑疾病患者,随机选取10例典型患者的移动式头颈MRI图像和3.0T常规MRI图像,比较其不同序列信噪比(SNR)、对比噪声比(CNR)的差异;选取31例特殊患者(行气管插管或气管切开、呼吸机辅助呼吸等)为特殊患者组,30例普通患者为普通患者组,比较2组患者移动式头颈MRI图像综合诊断度评分的差异;统计比较3.0T常规MRI和移动式头颈MRI不同序列噪声强度的差异;招募神经外科中心自2022年7月至8月住院的20名听力正常的志愿者,先后行3.0T常规MRI与移动式头颈MRI扫描,采用5分制法评价常规3.0T MRI、移动式头颈MRI不同序列的主观噪声强度。结果与3.0T常规MRI图像比较,移动式头颈MRI图像T1WI、T2WI、液体衰减反转恢复(FLAIR)序列的SNR、CNR均降低,差异均有统计学意义(P<0.05)。特殊患者组和普通患者组移动式头颈MRI图像综合诊断度评分的差异无统计学意义(P>0.05)。与3.0T常规MRI比较,移动式头颈MRI不同序列的噪声强度均明显减低,差异均有统计学意义(P<0.05)。与3.0T常规MRI比较,志愿者对移动式头颈MRI不同序列的噪声强度评分均明显增高,差异均有统计学意义(P<0.05)。结论移动式头颈MRI系统于床旁扫描时安全便捷,成像质量达标,患者舒适度高,适合在神经外科应用。Objective To explore the clinical application of portable head and neck magnetic resonance imaging(MRI)device in neurosurgery.Methods A total of 213 patients with brain diseases who were scanned by portable head and neck MRI device in Center of Neurosurgery,Zhujiang Hospital,Southern Medical University from June to September 2022 were selected.The portable head and neck MRI images and 3.0T conventional MRI images of 10 randomly selected patients were compared;the differences in signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of different sequences were analyzed.Thirty-one patients accepted tracheal intubation/tracheotomy,or ventilator-assisted breathing were selected as special patient group,and another 30 patients were as general patient group;the differences in comprehensive diagnostic scores of portable head and neck MRI images were compared.Noise intensity differences in different sequences between 3.0T conventional MRI and portable head and neck MRI were statistically compared.Twenty hospitalized volunteers with normal hearing in our center from July to August 2022 were selected,conventional 3.0T MRI and portable head and neck MRI were performed successively,and the noise intensity of different sequences in them was evaluated by using a 5-point system.Results Compared with those in 3.0T conventional MRI images,the SNR and CNR of T1WI,T2WI,and Liquid attenuated reverse recovery sequence(FLAIR)sequences in portable head and neck MRI images were significantly lower(P<0.05).No significant difference was noted in the comprehensive diagnostic scores of portable head and neck MRI images between special patients and general patients(P>0.05).Compared with that in the 3.0T conventional MRI,the noise intensity of different sequences in portable head and neck MRI was significantly reduced(P<0.05).These volunteers had significantly reduced noise intensity scores of different sequences in portable head and neck MRI compared with that in conventional 3.0T MRI(P<0.05).Conclusion Portable head and neck MRI device i
