The validity and use of computed tomography attenuation values. Williams G, Bydder GM, Kreel L. Br Med Bull. 1980 Sep;36(3):279-87 Seems to be general article. Early in history of CT Considerable investigation of: 1. CT number of liver - fatty and iron content 2. Bone density - measurement was reimbursed. 3. Density corrections in radiation dose calculations (both for risk of diagnostic and radiation treatment planning). Below are novel applications of measurements of CT numbers.
