Imaging techniques (MRI, PET)

Imaging techniques like MRI (Magnetic Resonance Imaging) and PET (Positron Emission Tomography) are tools used to visualize the inside of the body. MRI uses strong magnetic fields and radio waves to produce detailed images of soft tissues, such as the brain or muscles, helping diagnose various conditions. PET involves injecting a small amount of radioactive material, which emits signals detected by a scanner, highlighting areas of metabolic activity. This helps identify things like cancer or brain activity. Both techniques provide critical insights for diagnosis and treatment planning without surgery or invasiveness.
