Nearly all of the equations are simple proportionalities, and the meanings of many of them are illustrated in the Exercises. The properties of the linear, exponential and sine functions, and the rudimentary ideas about probability and statistics that are needed, are reviewed in appendices to the chapters where they are introduced.
New chapters in this edition include "Nuclear Cardiology, SPECT and PET";"Spiral and Multi-Slice! CT";"PACS, IMACS, and the Integrated Digital Department"; and a chapter on emergency response to radiological disasters and the roles that radiologists could assume.
