Bowel gas artifact meaning5/27/2023 ![]() This is most common because of bowel loops in the way or abundant fat tissue which the sound waves have to get through. The radiologist saying that there is limited visualization of the pancreas on ultrasound is common in ultrasound. These testS also do not depend on the skill of the technologist as much. But CT or MRI will allow a more detailed view. The reason ultrasound is done, is because it’s quick, cheaper, and does not use radiation. In these cases, CT or MRI will often allow a very detailed evaluation. In cases, where ultrasound does not allow a complete evaluation of the pancreas, the radiologist will note this in his report.
