Usefulness of Compress Sense Technique With 1.5T Magnetic Resonance Hydrography of inner ear: Comparison of Image Quality and Acquisition Time

Motivation: Minimize scanning time while ensuring the quality of MRH images. Goal(s): This study investigated the feasibility of using compressed perception acceleration sequences to evaluate the quality of MRH images. Approach: We compared data from traditional sequences and CS sequences with different acceleration factors. Results: The results showed that CS4 can guarantee diagnostic requirement with 44%time reduction. Conventional images were more commonly used than CS SPACE images for radiologists. However, CS4 SPACE images still get more than 3-point. This suggests that CS4 SPACE images is still considered acceptable. Impact: This preliminary study showed that for the MRH of inner ear, T2 SPACE sequence with 4-fold CS technique provided similar image quality to conventional T2 SPACE with 44% shorter scan time. Therefore, we can save a lot of examination time.
