Radiology employs various imaging modalities to detect and diagnose cancer early. Common techniques include:
- X-ray: Often the first imaging test conducted, useful for detecting abnormalities in bones and certain organs. - Computed Tomography (CT): Provides cross-sectional images of the body, allowing for detailed examination of tissues and organs. - Magnetic Resonance Imaging (MRI): Utilizes magnetic fields and radio waves to produce detailed images, particularly useful for soft tissues like the brain and muscles. - Ultrasound: Uses sound waves to create images, often used to examine soft tissues and guide biopsies. - Positron Emission Tomography (PET): Combined with CT or MRI, it helps in assessing the metabolic activity of tissues, crucial for detecting cancer spread.
