Hints
• You could repeat the same protocol simply by click-
ing the chronicle with the right mouse button for
“repeat“. E.g. when both non-contrast and contrast
studies are required.
• Water, rather than positive oral contrast agents
should be used. Give the last cup 200 ml just prior to
positioning the patient. To ensure adequate filling of
the duodenal loop, lay the patient on the right side
for 5 minutes before performing the topogram.
• A pre-contrast examination is usually performed
only if no CT scans were previously acquired, to
exclude calculi in the common bile duct and to visu-
alize possible lesions in the liver.
