Cost of Pet Scan
Cost of PET Scan is comparitively higher than the other diagnostics as You’re not just paying for the equipment, the power it uses, or a technician to run the test. You’re also paying for all the time and research that went into developing and producing the machine, which determines how much it’ll cost to lease. The cost of research and development is what inflates lots of prices in medicine. With Best Medical Savings TM you can save upto 40% on Cost of PET Scan. Call us and save.
Positron Emission Tomography (PET Scan)
A positron emission tomography (PET) scan is a unique type of imaging test that helps doctors see how the organs and tissues inside your body are actually functioning.
The test involves injecting a very small dose of a radioactive chemical, called a radiotracer, into the vein of your arm. The tracer travels through the body and is absorbed by the organs and tissues being studied. Next, you will be asked to lie down on a flat examination table that is moved into the center of a PET Scanner — a doughnut-like shaped machine. This machine detects and records the energy given off by the tracer substance and, with the aid of a computer, this energy is converted into three-dimensional pictures. A physician can then look at cross-sectional images of the body organ from any angle in order to detect any functional problems.
Why are PET Scans required?
PET Scans are generally used alongside X-rays or MRI (magnetic resonance imaging) scans. Doctors use PET Scans as a complementary test to these main ones. They are used to make a diagnosis or to get more data about a health condition. As mentioned above, they are also useful in finding out how effective current treatment is. The use of combined imaging technologies may hold the key to stopping – and even preventing – heart attacks, a study revealed.
The biggest advantage of a PET Scan, compared to an MRI scan or X-ray, is that it can reveal how a part of the patient’s body is functioning, rather than just how it looks. Medical researchers find this aspect of PET Scans particularly useful.
How should I prepare for a PET Scan?
A PET Scan is usually done on an outpatient basis. Your doctor will give you detailed instructions on how to prepare for your scan, including what you may or may not eat or drink before your exam. Before undergoing the scan, be sure to tell your doctor of any medications—prescription and over-the-counter—that you are taking as well as any herbal medications and vitamins. If you are taking certain medications or have certain diseases, such as diabetes, you will be given specific instructions regarding preparation for your scan. Generally, most patients are told not to eat anything for a minimum of 6 hours before the scan. Heart patients are also told to not take any product with caffeine for at least 24 hours. Be sure to wear comfortable clothes to your appointment. You may be asked to change into a hospital gown during the test. In those patients that need an assessment of the area near the bladder, a bladder catheter may need to be inserted.
It is essential to tell your doctor if you are pregnant or think you might be pregnant before undergoing a PET Scan because of radiation exposure.
How long does the test take?
Once injected into a vein, it typically takes from 45 minutes to 1 hour for the radiotracer to travel throughout the body and be absorbed into the organs or tissues to be examined. The scan itself may take another 30 to 60 minutes. The heart and brain studies take less time for imaging. You will be asked to remain still for the entire length of the exam, since motion will reduce the quality of the images. Depending on which organ is being examined, there may be additional tests and additional dyes or chemicals used that may lengthen the total appointment time up to 3 to 4 hours. For example, patients being examined for heart disease may undergo a stress test in which PET Scans are obtained while at rest followed by the administration of other drugs to examine blood flow to the heart under exercise conditions.
Does the PET Scan pose any risks?
Although a radiotracer chemical is used in this test, the amount of radiation you are exposed to is low. The dose of tracer used is so small that it does not affect the normal processes of the body. However, the radiotracer may expose the fetus of patients who are pregnant or infants of women who breastfeed to the radiation. You and your doctor need to consider this risk compared with the need for and potential information to be gained from the PET Scan.
PET Scans are commonly used to investigate the following conditions:
- Epilepsy – it can reveal which part of the patient’s brain is being affected by epilepsy. This helps doctors decide on the most suitable treatments.MRI and/or CT scans are recommended for people after a first seizure, this study explains.
- Alzheimer’s disease – it is very useful in helping the doctor diagnose Alzheimer’s disease. A PET Scan that measures uptake of sugar in the brain significantly improves the accuracy of diagnosing a type of dementia often mistaken for Alzheimer’s disease, a study revealed.
- Cancer – PET Scans can show up a cancer, reveal the stage of the cancer, show whether the cancer has spread, help doctors decide on the most appropriate cancer treatment, and give doctors an indication on the effectiveness of ongoing chemotherapy. A PET Scan several weeks after starting radiation treatment for lung cancer can indicate whether the tumor will respond to the treatment, a study showed. This article looks at whether PET Scans are beneficial during cancer diagnosis, staging and monitoring.
- Heart disease – a PET Scan helps detect which specific parts of the heart have been damaged or scarred. Any faults in the working of the heart are more likely to be revealed with the help of a PET Scan. A study revealed how comprehensive diagnosis of heart disease based on a single CT scan is possible.
- Medical research – researchers, especially those involved in how the brain functions get a great deal of vital data from PET Scans.
Types of PET Scans
Brain PET Scan
A brain positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease or injury in the brain.
Unlike magnetic resonance imaging (MRI) and computed tomography (CT) scans, which reveal the structure of the brain, a PET Scan shows how the brain and its tissues are working.
Heart PET scan
A heart positron emission tomography (PET) scan is an imaging test that uses a radioactive substance called a tracer to look for disease or poor blood flow in the heart.
A heart PET scan can tell your doctor whether areas of your heart muscle are receiving enough blood, if there is heart damage, or scar tissue in the heart.
Lung PET scan
A lung positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease in the lungs, particularly lung cancer.
Who should not have a PET Scan?
Pregnant women and women who are breastfeeding should not have a PET Scan as there is a risk for the baby. Any woman who is pregnant should tell her doctor straight away (before the scan).
Anybody who has just had a PET Scan should stay away from pregnant women, babies and young children for a few hours after the scan.
