This chapter, found in the chest pain section of the book, provides a succinct synopsis of a key study examining the use of computed tomography (CT) for diagnosing pulmonary embolism. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Researchers found that combined multidetector scanning has higher sensitivity than use of a single detection method, with high positive predictive value when scanning and clinical assessment concordance; when they do not, additional testing is indicated. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.
