Positron Emission Tomography (PET) Scanners reveal early indicators of cancer, heart problems and brain issues. An infusion of a secure radioactive tracer that aids in the identification of sick cells is required. An imaging test called a positron emission tomography (PET) scan creates pictures of your organs and tissues in action. The test employs a harmless, injectable radioactive substance called a radiotracer and an equipment called a PET scanner. When sick cells absorb a lot of the radiotracer, the scanner picks this up as a possible health issue. Positron Emission Tomography (PET) Scanners are commonly used by medical professionals to evaluate cancer treatments and aid in cancer diagnosis. The scan can be used to evaluate certain heart and brain conditions.
X-rays are used in computed tomography (CT) examinations. Magnets and radio waves are used in magnetic resonance imaging (MRI) examinations. Both generate static photos of bodily parts and organs. A radioactive tracer is used in PET scans to demonstrate how an organ is operating in real time. Compared to CT and MRI scans, PET scan pictures can identify cellular changes in organs and tissues early. Your doctor could conduct a PET scan and a CT scan simultaneously (PET-CT). The 3D pictures generated by this combined test provide more precise diagnosis.
