Synopsis

Keywords: DWI/DTI/DKI, Cancer, gastric cancer; magnetic resonance imaging; diffusion weighted imaging; T staging; MUSE; FOCUS MUSE

Motivation: DWI is a powerful technique, but poor image quality has remained a key limitation, hindering diagnostic accuracy for gastric cancer.

Goal(s): To compare the image quality and T staging performance of FOCUS MUSE DWI and the MUSE DWI in gastric cancer.

Approach: The image quality was evaluated using a five-point scale qualitatively. Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated in measurable lesions. The preoperative T staging accuracy for gastric cancer patients was assessed based on two sequences.

Results: The FOCUS MUSE exhibited superior image quality and performance in comparison to MUSE DWI for T staging.

Impact: The FOCUS MUSE DWI is a better imaging protocol for the T staging assessment of gastric cancer patients, compared with the MUSE DWI.
