PET and CT scan for Parkinson’s disease inflicted persons
If you or someone you know have had this illness diagnosed, you may need to go for a PET or a CT scan, so here is some first point information on what it is, and what you may need to do to get prepared for each scan.
A positron emission topography scan, or more commonly known as a PET scan, is where a small amount of radioactive tracer is injected to the body, from which reactions in the cells can be monitored. This allows your doctor to look at your organs from every possible angle, and better determine the treatment options available. A PET scan usually takes about 45 minutes to an hour, and during the procedure, depending what area of the body which is scanned, metal jewellery must be removed, including braces and other fixed objects. Before undergoing a PET scan it’s important to inform your doctor of all medications which you may have used, this includes over the counter medicines from your pharmacist. After the scan, you will be asked to drink plenty of fluids to help your body get rid of the trace substance used.
A CT scan, also known as a Computed Tomography scan, is like an ex-ray machine, which also allows your doctor to look closer at your brain. Before a CT scan you usually have a blood test to ensure that there will be no complications form the scan. During the procedure a contrast material is injected which helps the image, and during this time it’s important that you are very still, as movement may blur the image. A CT scan is usually between 15 minutes to an hour. Common sensations for the ones receiving the scan is a metallic taste and feeling flustered, however you can expect that your doctor will go through the procedure with you in detail.
Hopefully you are a bit more informed when it comes to these scans commonly used to aid in finding the best way forward for patients with Parkinson’s disease. Lastly, never hesitate to ask any questions that come up, your doctor will be more than happy to give you answers and calm your mind if you are worried.
