Image Quality
 
The quality of magnetic resonance imaging is particularly dependent on image resolution (matrix, field of view, slice thickness), contrast (TE, TR), signal to noise ratio (bandwidth, signal averaging) and lack of artifacts. These MRI parameters are affected by the field homogeneity, the field strength, the coil, the pulse sequence type and imaging techniques like parallel imaging.
See also Image Contrast Characteristics.

Perflubron® is a perfluorochemical for use as an oral contrast agent. Due to its insolubility in water it does not mix with intestinal secretions; thus bowel lumina appear homogeneously dark on MR images when Perflubron® replaces bowel contents. Filled bowel loops appear black with all pulse sequences because the contrast agent lacks mobile protons.
It is commercially available as Imagent GI. Because rapid transit through the gastrointestinal tract it reaches the rectum within 30 to 40 minutes in most patients. MR imaging of the upper abdominal region should begin within 15 minutes and of the pelvic region 15 to 60 minutes after ingestion of perflubron.
