Remote reading of coronary CTA exams using a tablet computer: utility for stenosis assessment and identification of coronary anomalies

Research output: Contribution to journalArticle


The feasibility of remote reading of coronary CT examinations on tablet computers has not been evaluated. The purpose of this study is to evaluate the accuracy of coronary CT angiography reading using an iPad compared to standard 3D workstations. Fifty coronary CT angiography exams, including a spectrum of coronary artery disease and anatomic variants, were reviewed. Coronary CT angiography exams were interpreted by two readers independently on an iPad application (Siemens Webviewer) and a clinical 3D workstation at sessions 2 weeks apart. Studies were scored per vessel for severity of stenosis on a 0–3 scale (0 none, 1 0.05). Both readers identified 100 % of coronary anomalies using each technique. Reading of coronary CT angiography examinations on the iPad had no influence on stenosis assessment compared to the standard clinical workstation.
