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

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.
