positron emission tomography Sentence Examples
- Positron emission tomography (PET) is a medical imaging technique that utilizes radioactive tracers to create detailed images of metabolic activity in the body.
- PET scans are commonly used to diagnose and monitor various diseases, including cancer, heart disease, and brain disorders.
- During a PET scan, a small amount of a radioactive tracer is injected into the body, which then accumulates in areas with high metabolic activity.
- The tracer emits positrons, which then interact with electrons in the body, producing gamma rays.
- These gamma rays are detected by a scanner and converted into images that show the distribution of the tracer and, by extension, the metabolic activity in the body.
- PET scans provide valuable information about the function and metabolism of tissues and organs.
- PET is often combined with computed tomography (CT) to create fused images that combine anatomical and metabolic information for more precise diagnosis.
- PET scans have revolutionized the field of medical imaging, enabling doctors to visualize and understand metabolic processes in the body in a non-invasive manner.
- The advancement of PET technology has led to the development of new tracers that target specific biological processes, allowing for more specific and accurate diagnoses.
- PET scans play a crucial role in personalized medicine, helping guide treatment decisions and monitoring patient response to therapy.
