What does PET-CT mean?

Emission Tomography-Computed Tomography (PET-CT) is a medical imaging technique that combines two imaging technologies: Positron Emission Tomography (PET) and Computed Tomography (CT) into a single examination. This combination provides detailed information about both the structure and function of tissues and organs in the body.
PET scan involves the use of a small amount of a radioactive tracer substance, often a form of radioactive sugar like Fludeoxyglucose (FDG), which is injected into the patient's body. The tracer is taken up by cells that are using a lot of energy, such as cancer cells. The PET scanner detects the radiation emitted by the tracer, creating images of the areas where the tracer is concentrated and using the data to generate images of the body's internal metabolic activity.
CT scan involves taking X-ray images from multiple angles around the body. These X-ray images are then processed by a computer to create cross-sectional images (slices) of the body's internal structures.
PET-CT is commonly used in the diagnosis, staging, and monitoring of various medical conditions, particularly cancer.
