Study Notes
Principle and Technology
- CT scanners use multiple X-ray beams and detectors that rotate around the patient to capture data.
- A computer processes this data to produce cross-sectional images of the body.
Common Applications
- CT scans are used for cross-sectional imaging, providing detailed internal structural information.
- They aid in cancer detection and staging by visualizing tumors and metastases.
- CT scans are useful for rapid trauma evaluation, allowing for quick assessment of injuries.
Advantages and Limitations
- CT scans offer detailed images, are quick to perform, and are excellent for visualizing complex anatomy.
- However, CT scans have limitations, including a higher radiation dose and potential allergic reactions to contrast agents.
