Dobutamine Myocardial Perfusion Scan

Dobutamine myocardial perfusion scanning 2 day protocol.

Day 1. The Rest Scan.
  1. No food or fluid for 4 hours before the test. Fast overnight for a morning appointment, light breakfast for an afternoon appointment.
  2. No caffeine for 48 hours before the rest scan (coffee, tea, pop drinks and chocolate).
  3. A small dose of radioactive material is injected and 20-30 minutes later a heart scan is performed.
Day 2 The Stress Scan.
  1. No food or fluid for 4 hours before the test. Fast overnight for a morning appointment, light breakfast for an afternoon appointment.
  2. No caffeine for 48 hours before the stress scan (coffee, tea, pop drinks and chocolate).
  3. Stop beta-blockers for 48 hours before the stress scan (see list below).
  4. Stop calcium channel blockers for 48 hours before the stress scan (see list below).
  5. No nitrates on the day of the stress scan (see list below).
  6. You will have an intravenous inserted into the L) elbow area and be hooked up to a heart monitor.
  7. You will then receive an intravenous infusion of Dobutamine. This may take 20-30 minutes. This enables us to get your heart rate up to a level where the heart is stressed.
  8. A second dose of radioactive material will be injected and a second stress scan of the heart taken 20-30 minutes later.
