  • Do not eat any solid food for 4 hours prior to the study.
  • Do not take medications for erectile dysfunction (e.g., Viagra® (Sildenafil), Cialis® (Tadalafil), and Levitra® (Vardenafil)) for 72 hours prior to the exam.
  • Please take all other medications as usual.
  • Inform your doctor or radiologist if you are having an acute asthma "flare-up" as you should not take Metroprolol (given to you as a part of the exam).
  • You should always inform your doctor and X-ray or CT technologist if you are or might be pregnant.
