What is a PET/CT scan?

PET/CT scans combine computed tomography imaging with another type of imaging known as positron emission tomography to provide a more detailed, useful image for your radiologist. Dr. Deepak Das and the other radiologists at Excel Medical Imaging offer high-quality, accurate PET/CT scans. To schedule a PET/CT scan, contact the office in New Port Richey, Florida, online or by phone today.


How does it work?

A PET scan uses a small amount of radioactive material, which is known as a radiotracer, to evaluate the function of your organs and tissues. This scan allows your doctor to identify changes in your body at the cellular level, which may detect the start of certain diseases that wouldn’t be visible on other scans, such as cancer.

Excel Medical Imaging uses a machine that combines PET technology with computed tomography, or CT, to provide better quality images.

What is the purpose of this scan?

Your doctor may recommend a PET/CT scan for many different reasons. Some of the most common uses of a PET/CT scan are:

  • Detecting new or recurring cancer
  • Evaluating the spread of cancer in your body
  • Monitoring the effectiveness of cancer treatment
  • Looking at the function of your brain and heart
  • Looking for abnormalities in your brain
  • Evaluating blood flow to your heart

How do I prepare for a PET/CT?

Before your PET/CT scan, you shouldn’t eat, chew gum, or drink anything but water for at least six hours. You should avoid alcohol, nicotine, and caffeine for at least 12 hours before the test.

If you are an insulin-dependent diabetic, you may consume a small amount of juice and toast at least two hours before the exam so you can take your insulin. If your blood sugar is higher than 150 mg/dl before the test, it may be rescheduled.

For at least one day before the PET/CT scan, avoid strenuous exercise and try to drink at least 32 ounces of water. If your PET/CT scan involves your brain, you shouldn’t take any psychotropic medications during the 24 hours immediately before your test.

Be sure to tell the staff at Excel Medical Imaging if you’re pregnant, nursing, or diabetic. You must also provide a written prescription from your physician that includes your medical history, surgical history, and the reason for the scan. In addition, you should provide the staff with a complete list of medications you’re taking prior to the test.
