Free-Breathing Dynamic Pancreatic MRI Using Stack-of-Stars Radial Sampling Algorithm and Compressed SENSE

Dynamic contrast-enhanced imaging is an essential examination in pancreatic MRI. However, non-diagnosable image quality due to motion artifacts and inappropriate scan timing for pancreatic phase are common problems. Recently, free-breathing sequence (4D FreeBreathing) has been introduced and it can provide diagnosable image quality even in free-breathing. In this study, we evaluated the feasibility of 4D FreeBreathing in pancreatic MRI. Our results showed that 4D FreeBreathing could provide diagnosable image quality and appropriate pancreatic phase scanning could be achieved in all examinations.
