Abstract:
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 is easy to use, enjoying high safety, imaging quality and suitability, which meets the clinical needs for neurosurgery patients.
