Positron Emission Tomography (PET) is an advanced nuclear imaging technique that provides highly detailed functional information about tissues and organs. Unlike conventional imaging methods that show anatomical structures, PET scans measure metabolic activity, molecular interactions, and biochemical processes inside the body — often detecting disease earlier than CT or MRI.

Today, PET imaging plays a critical role in oncology, neurology, cardiology, and precision medicine, helping physicians diagnose conditions accurately, plan treatments, and monitor therapy outcomes.
