Protons in -CH2- groups, e.g., contained in fatty emulsions, mineral or vegetable oil or sucrose polyester, have a fast relaxation and short T1 time.
These agents with short T1-relaxation, if used in gastrointestinal imaging, produce bright signal intensities in the intestine on T1 weightedsequences.
Palatable oil emulsions can produce appropriate contrast opacification of the stomach as well as the small bowel, but caused by absorption in the distal small bowel these materials are not suitable for use in MRIcolonoscopy.
(VIBE) A T1 weighted 3D FLASH breath hold technique with fat selective prepulse. Used for dynamic liver, pancreas, pelvis, thorax, orbita imaging and MR colonoscopy.
