Our aim is to assess the diagnostic accuracy of CE-MRA and DU in patients with peripheral arterial disease (PAD). Methods: Forty consecutive patients underwent DU, hybrid CE-MRA, and digital subtraction angiography (DSA). Magnetic resonance angiography and DSA images were evaluated independently and in a blinded fashion. Every segment was graded as normal, stenosed less than 50%, stenosed more than 50%, or occluded. Results: There were 1720 segments for analysis. Duplex ultrasound depicting stenosis &gt;50% demonstrated a sensitivity (S) 81.4%, specificity (E) 99%, positive predictive value (PPV) 96.2%, and negative predictive value (NPV) 94.8%. Occlusions showed S 90%, E 97%, PPV 98.1%, and NPV 88.4%. Magnetic resonance angiography depicting stenosis &gt;50% demonstrated a S 91%, E 99%, PPV 96.7%, and NPV 97.6%. Occlusions showed S 95.4%, E 98%, PPV 98.4%, and NPV 94.7%. Conclusion: Combined CE-MRA and DU is the first diagnostic approach in the preoperative assessment of PAD, leading to the use of DSA for selected cases<\/jats:p>","DOI":"10.1177\/1538574410377018","type":"journal-article","created":{"date-parts":[[2010,7,30]],"date-time":"2010-07-30T20:44:05Z","timestamp":1280522645000},"page":"576-585","source":"Crossref","is-referenced-by-count":9,"title":["Diagnostic Accuracy of Contrast-Enhanced Magnetic Resonance Angiography and Duplex Ultrasound in Patients With Peripheral Vascular Disease"],"prefix":"10.1177","volume":"44","author":[{"given":"Dra Alicia","family":"Bueno","sequence":"first","affiliation":[{"name":"Vascular Surgery Department, Hospital Universitario de Getafe, Madrid, Spain,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"Ac\u00edn","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, Hospital Universitario de Getafe, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dra Cristina","family":"Ca\u00f1ibano","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, Hospital Universitario de Getafe, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose L.","family":"Fernandez-Casado","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, Hospital Universitario de Getafe, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Castillo","sequence":"additional","affiliation":[{"name":"Radiology Department, Hospital Universitario de Getafe, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,7,30]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1053\/ejvs.2001.1503"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1053\/ejvs.2001.1490"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.1870150907"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2402050223"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.11.045"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2323030244"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2401041225"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-005-0068-2"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1016\/S1078-5884(03)00387-3"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-138-1-200301070-00012-w1"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.197.3.7480757"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ehj.2004.06.040"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1038\/ncpcardio1035"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2352040089"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2005.09.009"},{"key":"atypb16","doi-asserted-by":"publisher","DOI":"10.1258\/rsmacta.44.1.59"},{"issue":"2","key":"atypb17","first-page":"185","volume":"44","author":"Steffens JC","year":"2003","journal-title":"Comparison with intraarterial DSA.
