The advent of CT and MRI made the concept of image-based quantitation feasible. Early efforts involved drawing rulers, regions of interest, and volumes of interest, in addition to evaluating dimensions, average densities, and other imaging characteristics. This added a quantitative ability to a radiologist’s otherwise purely qualitative assessment of images. It exploited the capability of computers to do something that human observers are not good at: making measurements and quantitative assessments. It opened up the ability for radiologists to arrive at conclusions that went beyond what could be derived by interpretation of the anatomy alone.
