Visual vs. Quantitative Assessment - A New Viewpoint for Cardiac Function Using a Motion Tracking Method -

摘要

Once we have the numbers in hand, there is a mysterious tendency to accord them special value. These are the words written by John W. Keyes Jr in his review of ~18F-fluorodeoxyglucose standard uptake value in 1995. In any medical imaging modality, although visual evaluation is always fundamental, quantitative analysis has been developed to support our visual impression. As the quantitative methods progress and gain reliability, they gradually gain the attention of physicians in clinical diagnoses. When the reliability of the number is finally established, it confirms and modifies the visual diagnosis, and it even educates beginners for appropriate diagnosis.
