A PET/CT Scanner is a powerful hybrid imaging device that combines the capabilities of two advanced imaging techniques: Positron Emission Tomography (PET) and Computed Tomography (CT). This dual-modality scanner is widely used in modern healthcare for its ability to provide both functional and anatomical information in a single scan, making it invaluable in the diagnosis, staging, and monitoring of various diseases, particularly cancer. PET (Positron Emission Tomography) provides detailed images of the body's metabolic activity, helping detect abnormal cellular activity that may indicate conditions like cancer, heart disease, or neurological disorders. It detects the distribution of a small amount of radioactive material, which is absorbed by tissues and organs, providing insight into how they are functioning.
