CT Studies

WRA Contrast Policy For CT Exams: For contrast patients who are diabetic, have kidney issues, or age 65+, please fax BUN/Creatinine lab results to WRA prior to the appointment.

CT Premedication Protocol for Patients with
Allergies to Non-Contrast Products or Food

A two-drug pretreatment regimen is recommended to help reduce the likelihood of an allergic reaction in patients requiring IV contrast. This pretreatment regimen is necessary for your care if you have ever had an allergic reaction to ANY substance (medication or food) that involved moderate-to-severe allergic-like reactions such as marked facial or body swelling, severe difficulty breathing, laryngeal edema, body hives/diffuse rash, profound drop in blood pressure, cardiopulmonary arrest or other allergic-like reactions requiring hospitalization, ER treatment, or the need to carry an Epi pen. If you have any questions about your CT study or preparations, please contact the WRA office where your exam is scheduled and ask to speak with the Nurse.

Premedication Regimen

  1. Medrol (Methylprednisolone) 32mg Tablet
    • Take one tablet 12-14 hours prior to exam and one tablet 2 hours prior to your exam. If the Medrol strength per tablet is less than 32 mg, multiple tablets may be taken to equal 32 mg (i.e. 8 tablets of 4 mg strength).
    • WRA will provide a written prescription for Medrol which can be picked up at any WRA office. We can also fax the prescription to the pharmacy of your choosing. Please have this phone number available for us. If your exam includes oral contrast (Barium), the written prescription for Medrol and the Barium can be picked up at the same time.
    • Medrol is a corticosteroid. You must check with your referring physician for any contraindications or medical conditions before taking Medrol.
  2. Benadryl (Diphenhydramine) 50mg (Liquid or Tablet)
    • Take 50mg (liquid or tablet) 1 hour before your scheduled CT scan.
    • Benadryl is available as an over-the-counter (OTC) medicine; no prescription is needed.
    • Benadryl causes drowsiness; read package instructions carefully. You must arrange for transportation to and from your appointment.
