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 proces-
sing to be performed easily afterwards.
– For patients with bowel obstruction, only water or
water-soluble contrast can be used. Barium suspension
is a contraindication.
• Be careful when examining pheochromocytoma
patients. Administration of an IV CM injection in such
cases may trigger a hypertensive crisis!
For more information regarding the general use
of drugs and doses including specific indications and
contraindications mentioned in this guide, please
refer to page 2.
• To further optimize MPR image quality we recommend
that you reduce one or more of the following: colli-
mation, reconstruction increment, pitch factor while
using a wider slice width for image reconstruction.
