X-ray: Commonly used for detecting lung cancer and bone metastases. It uses low doses of radiation to create images of the inside of the body. Computed Tomography (CT) Scan: Provides detailed cross-sectional images of the body. Used for various types of cancers including lung, liver, and pancreatic cancers. Magnetic Resonance Imaging (MRI): Uses strong magnetic fields and radio waves to produce detailed images. It's particularly useful for brain, spinal cord, and musculoskeletal cancers. Ultrasound: Uses high-frequency sound waves to create images. Often used for breast, abdominal, and pelvic cancers. Positron Emission Tomography (PET) Scan: Uses radioactive tracers to measure metabolic activity. Often combined with CT scans to pinpoint cancerous tissues.
