Purpose: Prolonged scanning of time-resolved 3D phase-contrast MRI (4D flow MRI) limits its routine use in clinical practice. An echo-planar imaging (EPI)-based sequence and compressed sensing can reduce the scan duration. We aimed to determine the impact of EPI for 4D flow MRI on the scan duration, image quality, and quantitative flow metrics.

- This study compared the image quality of two types of diffusion-weighted imaging (DWI) techniques: echo planar imaging with compressed sensing-sensitivity encoding (EPICS-DWI) and conventional parallel imaging (PI-DWI) in healthy volunteers.
- Results showed that EPICS-DWI produced significantly higher signal-to-noise ratios (SNR) and better overall image quality at acceleration factors of 3 and 4 when compared to PI-DWI, although there were no significant differences in apparent diffusion coefficients (ADC) between the two methods.
- Despite EPICS-DWI showing improved quality, it also displayed a higher degree of image distortion at lower acceleration factors, indicating that optimal parameter settings are crucial for achieving the best imaging results.
Purpose: To assess the cervical magnetic resonance neurography (MRN) imaging quality obtained with compressed sensing and sensitivity-encoding (compressed SENSE; CS-SENSE) technique in comparison to that obtained with the conventional parallel imaging (i.e., SENSE) technique.
