3DMRCP Quantitative Image Quality: A Comparison Between CS-SENSE And SENSE And Its Acquisition Time

Motivation: Upgrading of MR scanner with compressed sensing (CS) could reduce acquisition time. Image quality of 3DMRCP with CS, however, need to be assessed quantitatively to ensure its standard despite of acceleration. Goal(s): We aimed to prove that 3DMRCP with CS can be employed in clinical practice with comparable quantitative image quality to SENSE and with shorter acquisition time. Approach: Quantitative image quality (signal intensity, noise, SNR and CNR) of 3DMRCP with CS and SENSE of the same subject that acquired at two different timepoints were compared retrospectively. Results: 3DMRCP with CS have maintained the quantitative image quality and has a shorter scan duration. Impact: 3DMRCP with CS only not can achieve higher spatial resolution but also with a shorter acquisition time while maintaining its quantitative image quality. Therefore, 3DMRCP with CS is recommended to be adopted in daily clinical practice.
