Study Notes
Computed Tomography (CT) Scanning
- Two key enabling technologies must be developed and perfected for CT to be successful in screening: low-dose scans and other unspecified technology.
Low-Dose Scans
- Human exposure to x-rays is generally considered harmful.
- The risks of patient radiation exposure have to be significantly lower than the risks of undetected pathologies that can be treated at early stages to impact the outcome.
- The benefit of CT screening examinations has to outweigh the risks of the additional radiation exposure.
CT Applications
- CT has become one of the most widespread modalities for diagnostic imaging due to the clarity and accuracy of images produced by CT scanners.
Cardiac Imaging
- There are two general types of cardiac applications: coronary artery calcification and coronary artery imaging.
- CT scans can illustrate coronary artery calcification and stenosis as a result of plaque.
- Calculation of ejection fraction from CAI (Coronary Artery Imaging) is possible.
CT Fluoroscopy
- CT fluoroscopy is a technique that combines CT and fluoroscopy capabilities.
Biopsy Operation
- Examples of a biopsy operation include CT-guided biopsies with depth-weighted volume-rendered views.
CT Perfusion
- Perfusion images of head and body scans can be obtained using CT.
- Perfusion images include CT images with contrast injection, contrast uptake curves in vessels, blood flow images, and mean-transit-time images.
Screening and Quantitative CT
- CT is moving into the area of screening, which implies that the patient under examination is asymptomatic.
