Guided Notes
Key concepts students will learn:
- •
An X-ray is a basic medical image that can help diagnose broken bones, some cancers, and infections, but it carries a small increased risk of cancer due to ionizing radiation.
- •
A CT scan uses hundreds of X-rays to create detailed cross-sectional images of the body, useful for diagnosing conditions like appendicitis and kidney stones, but it involves a higher dose of radiation compared to X-rays.
- •
An MRI uses magnetic fields and radio waves to produce detailed images of organs and soft tissues without using ionizing radiation, but it cannot be used if the patient has metal in their body and can be time-consuming and costly.
