The updated Second Edition of this best selling pocket guide is indispensable for everyone who must decide which imaging study to order in a patient workup. Written by top radiologists, What to Order When recommends the most efficient, cost-effective tests for 300 clinical problems. The eminent contributors include Charles Putman, Donald Resnick, Edward Sickles, Burton Drayer, N. Reed Dunnick, and Peter Callen. Organised by anatomic site for quick reference, the book addresses two common clinical situations: symptoms and signs that can't be narrowed down to a single working diagnosis...and clinical diagnoses that need to be confirmed, refined, or rejected by imaging procedures. For the former, the authors list differential diagnoses; for the latter, they outline typical signs, symptoms, and predisposing factors. Key information that influences the choice of imaging studies is presented in easy-to-scan outline format. Appendices summarise the basics of newer imaging modalities and the relative costs of individual procedures
