Abdomen
• In general, for abdominal studies such as liver, gall
bladder (query stones), pancreas, gastrointestinal
studies, focal lesion of the kidneys and CTA studies,
it is sufficient to use just water. Water is more effec-
tive than positive oral contrast agent in depicting the
linings of the stomach & intestines in post enhance-
ment studies. In addition, the use of water will not
obscure the blood vessels thus allowing CTA process-
ing to be performed easily afterwards.
• For patients with bowel obstruction, only water or
water-soluble contrast can be used. Barium suspen-
sion is contraindicated.
• Be careful when examining pheochromocytoma
patients. Administration of an IV CM injection in
such cases may trigger a hypertensive crisis!
• To further optimize MPR image quality, we recom-
mend that you reduce one or more of the following
parameters: collimation, reconstruction increment,
and slice width for image reconstruction.
• For abdominal studies deselect CARE Dose for
patients > 120 kg.
