Hypothesis
What types of artefacts can occur in PET/CT images and how can they be corrected?
Conclusion
PET/CT improves image quality and accuracy, but several artefacts can affect PET-corrected images, which can be minimized with proper correction techniques.
Supporting Evidence
- PET/CT systems combine PET and CT scanners to improve diagnostic accuracy.
- Artefacts in PET/CT images can arise from metallic implants, respiratory motion, and contrast media.
- Proper correction techniques can minimize the impact of artefacts on PET images.
Takeaway
PET/CT scans help doctors see inside the body better, but sometimes they can show false images because of things like metal in the body or how a person breathes.
Methodology
The paper reviews different types of artefacts in PET/CT images and discusses their correction methods.
Limitations
The study does not provide specific data on the frequency or impact of artefacts in clinical practice.
