The holy grails of health care are precision health and personalized medicine. While the two phrases may appear to be interchangeable, success in one leads to success in the other: achieving customized medicine will result in precision health for individuals and the public as a whole. Precision health is a type of medicine that takes into account a person's genetic, environmental, and societal elements in addition to their current health status. We anticipate a greater emphasis in the future on quantitative imaging technologies aimed at improving diagnosis and therapy choices, which we refer to as "Precision Imaging." Precision Imaging is not the same as "Precision Medicine," but it is supplementary to it. Precision medicine focuses on taking into consideration customised genetic, environmental, and lifestyle profiles (and their variability) in healthcare, whereas traditional diagnosis and categorization relied solely on individual phenotypes acquired from various medical examinations, including imaging.
