With CT, everyone who is receiving
contrast is required to be NPO (nothing by mouth) at least 6 hrs
before exam.
CT Stone Study’s, Abd/Pelvis w/o,
and Chest w/o also need to be NPO.
Any patient who is 60 and
over or diabetic, no matter what the age, is required to have a
creatinine lab exam prior to exam. This lab value can be up to
a month old.
If the patient is on the following
diabetic medications: Glucophage, Metformin, Glucovance,
Metaglip, Fortamet, Avandmet, Actoplusmet, or Riomet, he or she
is required to stay off these medications 48 hrs after the exam
and come back for a repeat creatinine before they can go back on
these medications.
Some patients may have to drink
oral contrast as well so your physician can look at your
digestive system.
