How do imaging techniques contribute to cancer diagnosis?
Imaging techniques play a crucial role in cancer diagnosis by providing detailed pictures of the inside of the body. MRI (Magnetic Resonance Imaging) uses magnetic fields and radio waves to produce high-resolution images of organs and tissues. CT scans (Computed Tomography) use X-rays to create cross-sectional images, which can reveal the size, shape, and location of tumors. PET scans (Positron Emission Tomography) involve the use of radioactive tracers to identify areas of high metabolic activity, often indicative of cancer cells. These imaging technologies help in early detection, staging, and monitoring of cancer progression.
