How do imaging technologies work in cancer detection?
MRI uses strong magnetic fields and radio waves to generate detailed images of the organs and tissues. It is particularly effective in identifying soft tissue abnormalities. CT scans utilize X-rays to create cross-sectional images, providing a clear view of the tumor's size, shape, and location. PET scans involve the use of radioactive tracers to detect metabolic activity and are often combined with CT scans (PET/CT) to provide comprehensive information about cancerous lesions.
