Positron Emission Tomography (PET) is a medical imaging technique that helps visualize and measure metabolic processes in the body. It is often used in clinical and research settings to assess conditions such as cancer, neurological disorders, and cardiovascular diseases. Here's how PET works: 1. **Radiotracer Injection**: A small amount of a radioactive substance, called a radiotracer, is introduced into the body, usually via injection.
PET radiotracers, or positron emission tomography radiotracers, are biologically active molecules labeled with a radioactive isotope that emits positrons. These tracers are used in PET imaging, a type of nuclear medicine that provides valuable insights into the metabolic processes of tissues and organs in the body. In PET imaging, a radiotracer is introduced into the body, typically through injection.
The Deauville criteria are a set of standardized imaging criteria used to evaluate the response to treatment in patients with lymphoma, particularly Hodgkin's lymphoma and aggressive non-Hodgkin lymphoma. They are primarily based on the use of positron emission tomography (PET) scans but can also involve computed tomography (CT) imaging. The criteria classify the metabolic activity of lymphoma after treatment into five levels, which helps clinicians determine whether a patient is responding to therapy.
Radiopharmaceuticals are specialized drugs that contain radioactive isotopes and are used primarily in medical imaging and therapy. They are designed for diagnostic and therapeutic purposes, particularly in nuclear medicine. ### Key characteristics: 1. **Radioactive Isotopes**: Radiopharmaceuticals consist of a radionuclide (radioactive isotope) attached to a pharmaceutical component, which can target specific organs, tissues, or cellular receptors in the body.
Single scan dynamic molecular imaging is a cutting-edge imaging technique that allows researchers to visualize dynamic processes at the molecular level in real time. This method typically combines advanced imaging technologies, such as fluorescence microscopy or computational imaging, with sophisticated analysis techniques to observe molecular interactions, conformational changes, and dynamic behaviors of biomolecules, cells, or tissues.
