ACR Appropriateness Criteria® Nontraumatic Aortic Disease

Abstract

Nontraumatic aortic disease can be caused by a wide variety of disorders including congenital, inflammatory, infectious, metabolic, neoplastic, and degenerative processes. Imaging examinations such as radiography, ultrasound, echocardiography, catheter-based angiography, CT, MRI, and nuclear medicine examinations are essential for diagnosis, treatment planning, and assessment of therapeutic response. Depending upon the clinical scenario, each of these modalities has strengths and weaknesses. Whenever possible, the selection of a diagnostic imaging examination should be based upon the best available evidence.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current

Aneurisma gigante de aorta torácica. A propósito de un caso clínico

“…La posibilidad de realizar una adquisición de las imágenes en TAC multicorte con una excelente resolución espacial, reconstrucciones isovolumétricas y tiempos de adquisición cortos, permite optimizar el uso del medio de contraste y obtener imágenes de angio-TAC. A partir de las imágenes adquiridas en el plano axial, se pueden hacer los posprocesos adecuados para localizar y caracterizar el aneurisma, realizar las medidas del mismo: diámetro transversal en el plano axial al vaso, diámetro de los cuellos, longitud del aneurisma, relación con troncos supraaórticos, evaluación de trombosis mural y signos de ruptura o prerruptura (9,10).…”

Development of a Computerized, Evidence-Based Decision Support System for Computed Tomography Assessment in Acute Aortic Syndrome in the Emergency Department

“…Prior to the use of algorithms, AAS was misdiagnosed in more than 30% of cases [6,7]. In 2010, the ACCF/AHA, along with other North American scientific societies and colleges published an algorithm for the diagnosis and management of AAS by stratification into three risk groups, using a scoring system based on the presence of defined risk factors: the Aortic Dissection Detection Risk Score (ADD-RS) [1].…”

“…Ultimately, the analysis and qualitative synthesis included 17 studies that were used to develop the decision support algorithm. These studies were mainly clinical practice guidelines [1,4], imaging appropriateness guidelines [5][6][7], systematic reviews [8][9][10][11][12][13][14] and metaanalysis [15] and other studies that evaluated risk factors for AAS [16,17]. No clinical prediction rules were identified.…”
