We developed a 4D radial fat-suppressed alternating-TR bSSFP sequence with T2-like contrast for abdominal free-breathing imaging of pancreatic cancer patients. The sequence was tested in healthy volunteers and patients with pancreatic cancer and provided images of the abdomen during different respiratory motion states of diagnostic quality.
