Translational Interventional Radiology, a volume in the Handbook for Designing and Conducting Clinical and Translational Research series, covers the principles of evidence-based medicine and applies these principles to the design of translational investigations in Interventional Radiology. The reader will come to fully understand important concepts including case-control study, prospective cohort study, randomized trial, and reliability study. Medical researchers will benefit from greater confidence in their ability to initiate and execute their own investigations, avoid common pitfalls in Interventional Radiology, and know what is needed for successful collaboration. Further, this reference is an indispensable tool in grant writing and funding efforts. The practical, straightforward approach helps aspiring investigators navigate challenging considerations in study design and implementation. This book provides valuable discussions of the critical appraisal of published studies in Interventional Radiology, elucidating the evaluation of the quality with respect to measuring outcomes and making effective use of all types of evidence in patient care. In short, this practical guide will be of interest to every medical researcher and interventional radiologist who has ever had a good clinical idea but not the knowledge of how to test it.
