Temporal Resolution
Temporal resolution is the capability of an imaging system to accurately image and display moving anatomy.
When Should You Favor Temporal Over Spatial Resolution?
- For imaging moving organs
- For imaging trauma and critically ill patients
- For imaging the chest and abdomen in patients who are unable to hold their breath
- For extended coverage, i.e.,
- Multi-organ screening
- Peripheral vessels
- Whole-body imaging
- For perfusion imaging
Trade-offs When Favoring Temporal Resolution
- Motion artifacts
-
- Blurred image
- Artifactually distorted anatomy
- Lower spatial resolution
-
- May miss smaller lesions
- Contrast enhancement may not be optimal over the entire area of interest
