How do I prepare for a pyelogram?
If you are allergic to Iodine or Shellfish you may not be able to have a CAT SCAN with contrast. In some cases premedication may be necessary to prevent an allergic reaction prior to CAT SCAN. A blood test called BUN and Creatnine must be done at least 30 days before having a CAT SCAN with contrast. The results must be normal. If you are currently taking Glucophage you must stop your does for 48 hours after your CAT SCAN. Repeat BUN and Creatnine at 48 hours. You may resume your normal dose of Glucophage if results are normal. If results are abnormal please contact your Primary Physician.
