The study aims to explore the feasibility of compressed
SENSE with different acceleration factors in 3D brain APTw imaging. Based on
the results, an accelerator factor of 5 is recommended with acceptable image
quality and significantly reduced scan (less than 2? min).

T2WI FLAIR; c. T1-Gd; d. APTw image by SENSE-1.6 fused with T2WI FLAIR image; e-h.
APTw images by CS-SENSE (with factors of 2, 3, 4, and 5) fused with T1-Gd image.
The ROIs were
obtained manually on the SENSE APTw image and copied to the others as shown.
