How does radiation help doctors Identify health problems in patients?

Radiation helps doctors identify health problems through imaging techniques such as X-rays, CT scans, and PET scans. These methods use controlled doses of radiation to create detailed images of the body's internal structures, allowing for the visualization of abnormalities like tumors, fractures, or infections. By analyzing these images, healthcare providers can diagnose conditions more accurately and develop appropriate treatment plans. Additionally, certain radiotracers can be used in nuclear medicine to assess organ function and detect diseases at an early stage.
