PET-CT Imaging Leads Us To More Informed Decisions About Your Care
What is PET-CT?
PET (Positron Emission Tomography) and CT (Computed Tomography) are both important diagnostic tools used to determine the presence and severity of cancers, neurological conditions, and cardiovascular disease, as well as to determine how well cancer is responding to therapy. PET-CT scans are both noninvasive and usually painless.
The PET scan uses nuclear medicine to detect abnormalities in cell metabolism and displays them as “spots” on the radiologists’ computer monitor, while the CT scan provides the precise anatomic location of these “spots”. By combining the two technologies into PET-CT, physicians can more accurately diagnose and monitor diseases such as cancer, heart disease, and brain disorders, while streamlining testing and decreasing the need for invasive biopsies.

How PET-CT works
To begin the procedure, a small amount of radioactive glucose is injected into the bloodstream through a small catheter (tube) into a vein in the hand or arm. There is no danger with this injection. Glucose (sugar) is a common substance the body needs in order to function. After the substance has accumulated in the area of the body being examined, it gives off energy in the form of gamma rays. The PET scan detects these rays and forms images of the location. The CT scan uses x-rays to make detailed pictures of the body’s internal structure. The entire scanning process takes approximately 30 minutes to complete.
Using both a PET and CT scan together increases accuracy in detecting abnormalities within the body which may provide your physician a unique opportunity in initiating a treatment plan earlier.
