Positron Emission Tomography (PET) and Computerized Tomography (CT) are both standard imaging tools that allow physicians to pinpoint the placement of cancer inside the physique earlier than making therapy suggestions. A nuclear medication scan is inexpensive and will yield extra exact data than exploratory surgical procedure. When detected by a PET scanner, the tracers help your physician to see how nicely your organs and tissues are working. Cancer begins as a primary illness affecting a single organ, however can grow to be deadly after it spreads to other organs.
The commonest radiopharmaceutical used in PET scanning is FDG (18-Fluorodeoxyglucose), which has a small amount of radioactive material, often known as a radiopharmaceutical, combined with sugar. PET scans show metabolic adjustments occurring on the mobile level in an organ or tissue.
The scan uses a particular dye containing radioactive tracers. PET scans may be used to see how effectively the treatment of certain diseases is working. Assess the effectiveness of a treatment plan, similar to cancer remedy. A PET scan is often an outpatient procedure.
By detecting radioactive glucose, the PET scan is ready to detect which areas of the brain are using glucose on the highest rates. Though most cancers spreads silently within the body, PET can inspect all organs of the physique for cancer in a single examination.
PET scans are often mixed with CT scans to produce even more detailed photographs. In many circumstances, it’s potential to obtain both a PET-CT or a PET-MRI scan. These scans can verify that areas of the heart that show decreased operate on the imaging are alive or scarred because of a previous heart attack.
