Why shouldn’t you exercise before a PET scan?

Many of us are not aware of the PET scan. Well, I would let you know some information regarding this PET scan. PET scan is imaging tested that allows your doctor to check for diseases in your body.  

A very special dye Containing radioactive tracers is either swallowed, inhaled, or injected into a vein of your arm based on which part of the body is to be investigated. The PET scan can measure blood flow, oxygen use, sugar level, etc. It is an outpatient procedure that is it’s being done within a day. 

PET scans are mostly used to detect cancer, heart problems, brain disorders including the central nervous system which includes Alzheimer’s disease, depression, epilepsy, Parkinson’s disease, head trauma. 

They are useful both for detecting cancer and for seeing if cancer has spread, to know how the cancer treatment is functioning, and also to check if the disease is intermittent. 

PET scans also let us know the areas of improper blood flow in the heart. Various colors and degrees of brightness on the scan will let us know the different levels of tissue work, which certainly helps you and your doctor decide where and how to proceed further. 

As you know glucose is the main fuel of the brain. When a PET- scan is done, the tracers are “connected” to compounds like glucose. The PET scan is capable to investigate those areas of the brain which are making use of glucose at the highest rate.

Does activity on a PET scan always mean cancer? 

Carrying out any type of activity actually is based on the organs where your doctors determine by examining it. The study says that the collision of any particular physical exercise will impact more pressure on the muscles. 

Persons who are undertaking PET scans should make themselves comfortable regardless of executing some exercises before the scan test then you should be letting your own neurologist know that you performed some activities. As he or she may make note of it to make them easy to judge when the results are out. 

Executing exercises before a PET scan can set off negative results of your scan report. In case you want better and best results then you have to stop exercising in an extreme way preceding your PET-scan day.

When you escalate, your exercising activity it can generate various difficulties to know the exact positive results of PET-scan as these types of scans are very diplomatic. So that does not mean that performing some activities on the day of PET-scan always meant to be cancer. 

This was some short fruitful information for you. Hopefully, it helps you out.
