Abstract：Objective To explore the clinical value of applying readout segmentation of long variable echo-trains (RESOLVE) sequence in the cranial magnetic resonance imaging (MRI) scanning to reduce the impact of magnetic sensitivity art ifacts caused by metal foreign bodies. Methods We retrospectively analyzed the sequence and sequence of single shot echo planar imaging (SS-EPI) in patients with magnetic sensitivity artifacts in our cranial MR routine scan from June 2018 to September 2019. The RESOLVE sequence was scanned, and the images were statistically analyzed using SPSS 26.0 data analysis software. Results The SS-EPI sequence images and RESOLVE sequence images of 30 patients with magnetically sensitive artifacts were compared and analyzed. The reduction rate of artifacts in patients scanned with RESOLVE technology was 30/30 (100%) compared with patients scanned with ordinary diffusion weighted imaging (DWI) technology. The RESOLVE sequence can reduce image distortion artifacts,
magnetic sensitivity artifacts, and improve the clarity of the image to the lesion and the overall quality of the image (P<0.001). Conclusion The RESOLVE DWI sequence can improve the magnetic sensitivity artifacts produced by metal dentures and clearly show the lesions.
