MRI provides comprehensive information on the full range of pancreatic diseases. This unit presents a protocol incorporating various types of sequences, including transverse and coronal data acquisitions, and with the routine use of intravenous gadolinium.
Materials
Basic Protocol: Imaging the Pancreas
Materials
-
Normal saline (0.9% NaCl), sterile, 40 ml minimum
-

What is MRCP in your question? Exacty what image quality do you want to improve? Have you tried the image parameters provided in the protocol?
sir i would like to know whether it is possible better quality MRCP result in hitachi Airis 2 MR System
