What is a Brain PET scan?
A brain PET scan( Positron emission tomography of the Brain) is an imaging procedure that allows doctors to see the functioning of your brain. Following the bloodstream absorption of radioactive "tracers," the scan records images of the brain's activity. The substances like glucose(the brain's energy source) have these tracers "attached" to them (sugar). The brain will use glucose more quickly in active areas than in passive ones. It can be seen through a PET scanner, which helps doctors assess how the brain is functioning and spot any anomalies.
Why is a brain PET scan performed?
The exam provides precise information about the brain's dimensions, structure, and functions. A brain PET scan, in contrast to conventional scans, gives medical professionals a picture of the brain's anatomy as well as its functionality.
