Value of Diagnostic Imaging: Information from Images addresses the concepts needed to answer questions on topics of value, such as how much to pay for diagnostic testing, how many tests are too many, do they cause harm, and whether or not patients need an MRI before a laboratory test. The book helps readers recognize when one diagnostic test is better than the other and when more information does not help. It provides an essential resource for radiologists, diagnostic pathologists, and health policy researchers involved in medical decision modeling, evidence-based medicine, precision medicine, public health and health economics.
