A positron emission tomography or a PET scan is an imaging test that helps reveal how the tissues and organs are functioning. A PET scan test uses a radioactive drug called tracer to show this activity. The tracer is generally injected, swallowed or inhaled, depending on the site of organ or tissue being examined. The tracer collects in areas of the body that have higher levels of chemical activity, and that often corresponds to the area of diseases. On a PET scan, these areas show up as bright spots.
A PET scan is useful in revealing or evaluating several conditions such as cancers, heart ailments, and neurological disorders. Often, PET images are combined with CT or MRI scans to generate a special diagnosis.
How PET Scans helps in detecting Cancer?
During PET Scans, cancer cells show up as bright spots because they have a higher metabolic rate than normal cells. PET scans help useful in:
What type of Cancer PET Scans helps in detecting?
PET scans must be analyzed and interpreted with expert help as more often noncancerous conditions can look like cancer, and some cancers do not appear on PET scans. Many types of solid tumors that do appear during PET scans are:
Brain Cervical Head and neck Lung
Colorectal Esophageal Melanoma Pancreatic
Thyroid Prostate Lymphoma
Should I eat before the PET scan?
No, the PET scan works directly from the amount of glucose or sugar in the body, and as we eat the levels of sugar increase in the blood and will interfere with the scan result.
How long does a PET scan last?
The initial part of the PET scan involves the injection of a radioactive isotope after which the patient has to wait for an hour before the scan will be done.
Why there is a gap between injection and scan?
One of the key points for PET scans is that the patient needs to rest before the scan in order to allow for the body to be as normal as possible in relation to muscle activity.
How is a PET scan different from a CT or MRI scan?
A PET scan reveals energy changes at a cellular level which allows detection of smallest cancers and differentiates between benign and malignant tumors whereas a CT or MRI detects structural organ or tissue changes that occur later with the more progressed disease.
