Study Notes
Magnetic Resonance Imaging (MRI)
- MRI uses powerful magnets and radio waves to produce images of the body.
- The technology measures the response of hydrogen atoms in tissues to generate images.
Applications of MRI
- MRI is used to produce detailed images of the brain and spinal cord in neurological imaging.
- It is used to visualize joints, ligaments, and muscles in musculoskeletal imaging.
- MRI is used to image the heart and blood vessels in cardiovascular imaging.
Advantages of MRI
- MRI provides superior soft tissue contrast compared to other imaging modalities.
- It does not use ionizing radiation, making it a safer option for patients.
Limitations of MRI
- MRI machines are expensive to purchase and maintain.
- Scan times for MRI are typically longer compared to other imaging modalities.
- MRI is contraindicated for patients with metal implants due to the strong magnetic fields.
