Importance of Non-Echo-Planar Diffusion Weighted Imaging (Non-EP-DWI) on Reducing Air-Bone Interface Artefact to Improve the Image Quality in Comparison with Echo-Planar Diffusion Weighted Imaging (EP-DWI) on MRI Brain
Divya G.
Abstract: Echo Planar Diffusion Weighted Imaging techniques were quick and commonly used to acquire the Brownian motion of water molecules in the body tissues. It is also extremely susceptible to artefacts as it causes air-bone interface in the diffusion-weighted MRI Brain images which affect the image quality. (Yoshizako et al., 2021) So, an alternative technique non-echo planar based Echo Planar called TSE-DWI sequence produces better image quality without air bone interface artefacts in the diffusion-weighted brain images. (Sheng et al., 2020) Aim and objective: The study aims to reduce the air-bone interface artefacts in the diffusion-weighted imaging to improve image quality in magnetic resonance imaging (Krupa & Bekiesinska-Figatowska, 2015). Methods and Materials: This is a cross-sectional study concentrated on certain factors that influence the image quality such as spatial resolution, signal-to-noise ratio, contrast-to-noise ratio and scan time. A total of 34 patients undergoing MRI Brain scans were included in the study. A set of two sequences, echo planar DWI and non-echo planar DWI were employed in the study for each patient using Phillips Ingenia 3 tesla MRI Scanner equipment and head coil. (Mas-Estelles et al., 2012). The radiologists did diagnostic analyses to evaluate the image quality. This study included the statistical analysis of Wilcoxon Man Whitney's Mean Rank test. Results: This study showed that the non-echo planar based diffusion-weighted imaging which is turbo spin echo sequence reduces the air-bone interface artefacts drastically when compared with echo planar diffusion weighted imaging sequence in the expense of longer scan times.
