This book is a visual introduction to interpreting CT image findings in patients with acute aortic pathology. More than 120 representative cases are presented from patients admitted to a state of the art acute aortic treatment center specializing in advanced aortic care. The case presentations include clinical information, imaging findings, and management decisions. Each case is accompanied by a key image and representative movie files.The clinical cases are organized to emphasize important lessons about making accurate diagnoses and to facilitate identification of specific pathologic and morphologic details. Initial cases demonstrate how to differentiate AAS from false positive findings, including imaging artifacts and other pathologies (differential diagnosis). Subsequent cases of patients with AAS are organized by pathology and by segmental anatomic location along the aorta proximal to distal (i.e., root to infrarenal segment).
