低场婴儿专用磁共振临床应用效果研究

Study on the Clinical Application Effect of Low-Field Infant MRI

摘要

摘要:
目的研究低场婴儿专用磁共振的临床应用效果。
方法采用文献综述法、专家咨询法及两轮德尔菲法确定评价指标体系，回顾性分析2023年1月—2024年12月低场婴儿专用磁共振和高场磁共振各指标数据并进行比较。
结果低场婴儿专用磁共振在信噪比、图像均匀性、扫描时间、用户界面友好性、图像结果一致性方面与高场磁共振存在一定的差距，但是在空间分辨率、图像质量、软件系统可靠性、硬件系统可靠性、平均故障间隔可比肩高场磁共振，在噪声及不使用镇静剂情况下完成的检查率优于高场磁共振。
结论低场婴儿专用磁共振满足临床诊断需求、性能稳定，可作为床旁脑部疾病常规筛查工具。

Abstract:
Objective Evaluate the clinical application effect of low-field infants MRI.
Methods Using literature review, expert consultation, and two rounds of Delphi to determine the evaluation index system. Then retrospectively analyze and compare the data of low-field infant MRI and high field MRI from January 2023 to December 2024.
Results There is a certain gap between low-field infant MRI and high field MRI in terms of signal-to-noise ratio, image uniformity, scanning time, user interface friendliness and image result consistency. However, there was no difference in terms of spatial resolution, image quality, software system reliability, hardware system reliability and average failure interval, the noise and the rate of examination completed without sedation is better than that of high field MRI.
Conclusion Low-field infant MRI meets needs of clinical diagnostic and has stable performance. It can be used as a routine screening tool for brain diseases near bed.
