PET/CT Clinical Trial
Official title:
Negative Oral Contrast Agents Utilization in PET/CT Studies
To compare the performance of different negative oral contrast agents in bowel distension in patient referred for PET/CT studies for various causes aiming for identification of ideal oral contrast agent(OCA).
Evaluation of gastrointestinal pathology depends on adequate bowel distention, which
optimizes resolution of the bowel wall and contents. Traditionally, high-attenuation oral
Contrast material in the form of iodine solutions or barium suspensions has been used to
obtain bowel distension in MDCT examinations
Traditional high-contrast oral agents like iodine solutions, and barium suspensions which due
to overcorrection problems in PET-CT interpretation lowers the accuracy of diagnosis.
Negative oral contrast agents like water, air, fat containing agents used with 12.5% corn oil
and polyethylene glycol has been used in radiological studies. Milk with 4% fat content has
also been tested out in radiological studies and found to be effective. As it is more easily
available, palatable, and acceptable especially, by children it needed to be tested in the
visualization of the GIT in the PET-CT studies compared to other negative contrast agents.
