What is a PET Scan?

Posted by stephanie on August 20th, 2007

I heard from the team at The Center today. My lab work continues to trend up which is the wrong direction. They are going to schedule me for a PET scan. Someone should call tomorrow with a date and time. A positron emission tomography (PET) scan is a unique type of imaging test that helps the team see how the organs and tissues inside my body are actually functioning. PET scans are most commonly used to detect cancer, heart problems, brain disorders and other central nervous system disorders.

A PET scan can measure vital functions such as blood flow, oxygen use, and glucose metabolism, which helps doctors identify abnormal from normal functioning organs and tissues. One of the main differences between PET scans and other imaging tests like CT scan or MRI is that the PET scan reveals the cellular level metabolic changes occurring in an organ or tissue. This is important and unique because disease processes often begin with functional changes at the cellular level. A PET scan can often detect these very early changes whereas a CT or MRI detect changes a little later as the disease begins to cause changes in the structure of organs or tissues. The scan can also be used to evaluate the effectiveness of my treatment plan, allowing the course of care to be adjusted if necessary.

So my mighty warriors let us pray:
Dear Lord,
We ask you to guide and direct the medical team helping them find clear direction and the identification of a treatment plan that will be successful in battling this disease. We pray for comfort and a sense of peace for all that are worried and fearful about this battle. We know through you all things are possible. We thank you for the many gifts you have given us.

Amen

Grace & Peace,

Stephanie
