Enhanced prostate imaging in ultra-low field MRI using a passive LC-resonator.

Motivation: As gold standard, MRI indeed matters in prostate imaging. The relative low image quality in ultra-low field MRI precludes its application in prostate imaging. Goal(s): Our goal was to improve prostate image quality in ultra-low field MRI, particularly emphasizing the target prostate region. Approach: We utilized an additional specially designed passive LC-resonator in imaging process. Results: By using the LC-resonator, the prostate image quality in ultra-low field MRI was improved, giving a higher image contrast to the prostate region. Impact: Adopting passive LC-resonator in imaging process is of highly cost effective, not only highlighting the target region, but offering a new imaging idea for other organs when it comes to bad SNR situations.
