Which resolution would be the most important when evaluating the heart with respect to motion?
A. 
Temporal
B. 
Axial
C. 
Spatial
D. 
Lateral
Correct Answer A. Temporal
Explanation The most important resolution when evaluating the heart with respect to motion would be temporal resolution. Temporal resolution refers to the ability to capture and distinguish rapid changes over time. In the context of evaluating the heart, it is crucial to have high temporal resolution to accurately assess the motion and function of the heart. This allows for the detection of abnormalities such as arrhythmias or abnormal contractions that may not be visible with lower temporal resolution.

B. 
Lateral
C. 
Spatial
D. 
Axial
Correct Answer A. Temporal
Explanation temporal resolution is worse with multiple focal zones but lateral resolution is improved
