There are many different types of imaging used to get an impression of the inside of a human body. X-Rays, CT scans, MRIs and PET scans are used daily; each one has specific strengths.
PET (Positron Emission Tomography) provides doctors with information about the way the body is functioning, and to check for disease. This type of scan helps doctors in their preparation for surgical procedures as well as following how well the patient is responding to treatments. PET scans are commonly used for diagnosing cancer as well as brain anomalies. Combined with an MRI or CT scan, the PET scan produces multidimensional images of the inner workings of the body. An MRI or CT scan provides an image of how the body looks while a PET scan reveals how the body is functioning.
When PET scans are used on cancer patients, the doctor can see if the cancer is spreading, if the treatment is working or whether cancer has returned. PET scans can also be used to check for Alzheimer’s and Parkinson’s disease.
PET Scan Procedure
The machine that is a large open circle, the patient lies on a table that moves in and out through the center. Once you have changed from your street clothes to a hospital gown, you will be given a tracer. The tracer emits radiation that is picked up by the machine; the tracer is always injected. After about an hour, your body will have absorbed the tracer, and the scan begins. A complete scan takes no more than 30 minutes, during this time; you must lie very still and avoid movement or talking.
