“Should I order an MRI or a CT for this indication?” - a question asked by healthcare providers more often than one might think. For-profit medical science creates innovation that benefits us all, no double about it. However, the frequent technological advances among the large imaging equipment manufacturers in order to gain competitive advantage can be tough to keep up with. Professor and Chair of Radiology at UC San Diego William Bradley, MD, PhD, sums it all up in this insightful little book written with the referring physician in mind. Simple recommendations on which studies to order for various parts of the body are laid out in a logical, succinct manner, with separate sections on the clinical implications of recent improvements in MRI and multi-detector CT technologies, and their appropriate roles for evaluating intracranial abnormalities, head and neck, musculoskeletal, and cardiac and abdominal applications. A wealth of information packed into a quick read, with links to resources offering more nuanced indications.
