A PET (Positron Emission Tomography) scan is an imaging technique that allows your doctor to evaluate how parts of the body are functioning. The PET scan can help to detect disease and help manage numerous different disease states, including, but not limited to: cancers, heart diseases, and brain disorders.
PET Scan
A positron emission test (PET) scan is an imaging test to show pictures of your tissues and organs while they work. Healthcare professionals will also occasionally use PET scans to monitor some brain and heart conditions.
The Application of PET Scan Technology
Cancer cells have a much higher metabolism than healthy cells because they are utilizing glucose to grow more rapidly. The physician is able to note the bright spots in the PET scan because the cancer cells hold onto a radioactive glucose based tracer, and the glucose will supply the cellular metabolism. This allows the physician.
Cardiovascular Assessment
PET imaging is performed to assess blood flow and ventricular viability in the heart. Normal heart tissue absorbs more tracer than either faulty tissue or viable tissue with less blood flow. The assessment of blood flow to the heart is valuable because it gives specificity to the location in the heart that is poorly perfused and has been subject to past heart
Infections Inflammation and Pre-Surgery Planning
As infections and inflammatory processes demonstrate very high metabolic activity, PET imaging can be used to detect and monitor infections, including bone and soft tissue infections. In addition, in the context of pre-surgical planning, especially for complex procedures like brain surgery and complex heart surgeries with perfusion.
Monitoring Treatment Response
PET imaging can play an important role in monitoring treatment response by making PET scan comparisons before, during, and after therapy to indicate changes in the metabolic activity of tumors or any other affected tissues.
Safety and Procedure
PET scans are non-invasive and typically performed as an outpatient procedure exposing a patient to a relatively low amount of radiation similar to natural exposure in the past few years. The test typically takes about one to two hours from the time of the injection of the tracer until the technician has collected the imaging data.
Conclusion
The purpose of PET imaging is to provide important information about the metabolic and functional state of tissues and organs, and for identifying disease at a very early stage, providing an accurate diagnosis (which could result in a different treatment plan), and appraisal of the progress of disease including cancer, cardiometabolic disease, and brain disease. PET imaging modality provides information on cellular activity, as opposed to only anatomical information, making it an important medical imaging modality in this day and age.
Frequently Asked Questions
Q. Why would a doctor want a PET scan?
the oncological, cardiac, and neurological realms.
Q. Will a PET scan show all cancer?
No, a PET scan does not show all cancers. While PET scans can be effective for the diagnosis, staging, and monitoring of particular cancers, they do have limitations.
Q. What is a PET scan commonly used for?
Certainly, no PET scan will detect all cancers. A PET scan can be useful for detecting, staging, and following cancers But, it does have limitations.
Q. What cancers cannot be detected by a PET scan?
PET scans are capable of detecting many types of cancers, however, some cancers are known to visualize poorly or not at all.
