Clinical Application And Image Quality Improvement Of Magnetic Resonance Cholangiopancreatography Using Different Oral Contrast Agents

Suppression of fluid signal in gastrointestinal tract using Oral contrast agent is a new and developing technique to improve the MRCP image quality in recent years. Up to now, oral administration of Gd-DTPA may be one of the best contrast agent in clinical practice. However, there are some issues on its optimal concentration, capacity and examination time in MRCP, which demands further investigation. Meanwhile, the clinic value of oral administration of Gd-DTPA in MRCP is also investigated in pancreaticobiliary duct diseases. Furthermore, we attempt to explore the clinical effect of oral barium sulfate, which is reported to be able to suppresse the fluid signal in gastrointestinal tract.Part. 1 Quality control of MRCP image using different oralcontrast agents1 Objective: Both in vitro and clinical trial of Gd-DTPA and BaSO₄ used as MRCP oral gastrointestinal tract contrast agent were performed and evaluated.2 Materials and methods2.1 Contrast media: Gd-DTPA (Kangchen Pharmaceutical Limited Company,...
