When is PET Imaging Conducted?
A
positron emission tomography scan is often used to help doctors diagnose,
monitor, and treat several cancers, including lung, lymphomas, and head and
neck cancer. They also help them find tumor locations and determine if
treatment is working for patients.
A PET scanner uses a radioactive tracer to show the abnormal
(cancerous) cells in the body. Doctors can
examine every part of a patient's body and identify cancer. Known as
Fluorodeoxyglucose (FDG), the radioactive tracer is often attached to
fluorine-18. When the glucose is absorbed by body cells, the fluorine-18 will
break down and release gamma rays and positrons.
Cancer
cells are always aggressive, and they grow and multiply fast as they take in
more sugar. On PET scans, cancerous cells will glow brighter.
Here is
why PET scans are conducted:
·
Sometimes
doctors perform PET scans on neurology and cardiology patients.
·
And
whenever a patient has symptoms, doctors will use a PET scan to determine the
proper test needed to identify a problem and give the appropriate treatment.
·
Cancer
that is discovered through PET imaging can be accurately staged based on its
size and the extent to which it has metastasized.
·
Follow-up
PET Scans are used to detect when a patient’s treatment is not working. This
allows oncologists to stop the current treatment and find an alternative one
that works well on the patient.
The
latest advances in PET technology have enhanced imaging by providing more
accurate and precise results during cancer diagnosis, staging, treatment, and
monitoring. The PET scanner can fuse images in the body to deliver the entire
picture of the cancerous tissue. This enhances the accuracy of diagnosis and
minimizes the need for more scans by a patient.
PET
imaging is a procedure that is entirely non-invasive and painless. It takes
only 30 minutes to get a PET scan.
