Positron Emission Tomography (PET) and
Computerized Tomography (CT) are both
standard imaging tools that allow
physicians to pinpoint the location of
cancer within the body before making
treatment recommendations.
The highly sensitive PET scan detects
the metabolic signal of actively growing
cancer cells in the body and the CT scan
provides a detailed picture of the
internal anatomy that reveals the
location, size and shape of abnormal
cancerous growths.
Alone, each imaging test has particular
benefits and limitations but when the
results of PET and CT scans are "fused"
together, the combined image provides
complete information on cancer location
and metabolism.
The bottom line is that you can have
both scans - PET and CT - done at the
same time.
Usage of PET/CT Scan
Cancer:
To assess
tumor aggressiveness
To monitor success of therapy
To detect early any recurrent tumors
To provide a whole-body survey for
cancer that may have spread
To identify benign and malignant
growths
Heart
Disease:
To
determine what heart tissue is still
alive following a suspected heart
attack
To predict
success of angioplasty (balloon) or
bypass surgery
To determine if coronary arteries
are blocked
Brain Disorders:
To
diagnose Alzheimer's and other
dementia
To determine the location of
epileptic seizures prior to surgery
