Cardiac PET Scans in Broward

Information Regarding Cardiac PET

Positron Emission Tomography (PET) scans show the chemical functioning of organs and tissues, while other imaging techniques – such as X-ray, MRI and CT scans – show structure. That makes PET technology particularly useful for the detection of coronary artery disease.



PET ScannerOur innovative, integrated equipment combines the best of these two imaging technologies. PET permits assessment of myocardial perfusion and metabolism with superior accuracy. The results help our physicians identify the extent of heart disease and know when to suggest revascularization to the patient.
How it works: Rubidium-82, a radioactive tracer that emits subatomic particles called positrons, is injected into the patient's arm. The blood stream carries the positrons to the heart muscle. A special PET camera detects the emitted positrons and constructs a picture of the heart.

PET scans reveal the health of the vessels supplying blood to the heart, heart muscle and surrounding tissue. The most common use of PET imaging in cardiology is to identify heart muscle weakened but not damaged irreversibly by blocked arteries – that information helps physicians determine whether a patient's heart muscle will benefit from coronary artery bypass surgery or angioplasty.

More facts about cardiac PET scans:

  • PET scans can detect over 95 percent of people who have significant blockages of coronary arteries and produce reliably normal results in over 95 percent of people with no heart disease.
  • PET scans are non-invasive and painless.
  • Sometimes, an intravenous medicine is used to stress the heart in conjunction with the PET scan.
  • PET scans rarely produce "false positives" (test results showing heart disease where none exists) — so they are often used to confirm other tests when a false positive is suspected.
  • The radiation you are exposed to during a PET scan is roughly equivalent to that of a kidney X-ray.
  • PET scans take about 60 minutes to perform.
  • Most people are candidates for PET scans. However, pregnant women, nursing mothers and people who have recently suffered stroke usually cannot have PET scans.
  • You will not have to exercise for this procedure

  8. The test takes approximately 1 (one) hour to perform.  Please plan accordingly.  You will not be required to walk on a treadmill for this test.
  9. Please bring a list of your current medications. In addition, do not take the following medications on the morning of the test.  You may take all the other medications except for those listed here:
*Nadolol *Inderal/Propranolol Hcl
*Lopressor/Metoprolol  *Cardizem/Diltiazem
*Toprol XL  *Corgard
*Sectral/Acebutolol  *Theodur
*Tenormin/Atenolol *Visken/Pindolol
*Kerlone/Betaxolol Hcl  *Blocadren/Timolol Maleate
*Normodyne/Trandate *Levatol/Penbutolol Sulfate
*Tekturna *Calan/Penbutolol Sulfate
*Coreg/Carvedolol  

**Diabetics - If you are insulin dependent or if you take pills for your diabetes, you may eat a small breakfast-enough to take your insulin injection or to take your pills without a reaction from having low blood sugar.

If it is absolutely necessary to cancel your scan, we require 48 hours notice.
