This study used magnetic resonance cholangiopancreatography (MRCP) to compare the image quality and acquisition time of conventional respiratory-triggered (RT), modified RT, and breath-hold (BH) sampling perfection with application-optimized contrasts using different flip evolutions (SPACE) sequences in patients with biliary and pancreatic disorders. Our results suggested that modified RT-SPACE-MRCP sequence can significantly reduced acquisition time and had better image quality. The MRCP sequence can be selected flexibly according to the patient's situation to obtain good diagnostic images.
