Abstract：Objective To compare and analyze the application value of three dimensional breath-hold gradient and spin-echo(3D BH-GRASE)and three dimensional respiratory-triggered turbo spin-echo(3D RT-TSE)sequence in magnetic resonance cholangiopancreatography(MRCP).Method The patients who underwent abdominal MRI due to suspected pancreaticobiliary lesions in our hospital from June 2019 to July 2021 were prospectively selected to receive 3D RT-TSE sequence and 3D BH-GRASE sequence MRCP scanning.The scanning time,image quality score and lesion display of the two sequences were com-pared.Results The scanning time of 3D BH-GRASE sequence was(16.4±1.7)s,which was significantly shorter than that of 3D RT-TSE sequence(258.6±31.2)s(P<0.05);The scores of main branches of gallbladder,intrahepatic bile duct,cystic duct,pancreatic duct and common bile duct in 3D BH-GRASE sequence were significantly higher than those in 3D RT-TSE se-quence(all P<0.05);The detection rate of lesions between the two scanning sequence methods was no significant difference(all P>0.05).Conclusion The application of 3D BH-GRASE sequence scanning in MRCP can ensure the image quality and dis-play the lesions,and shorten the scanning time.
