Patients and methods: A consecutive series of 23 patients with Moyamoya disease were analyzed retrospectively. Twenty three patients underwent 25 procedures of extracranial-intracranial bypass. Cranial CTA was performed within one week after the surgery to assess bypass patency. Then TOF MRA was scanned within 24 h after CTA on a 3T MRI system. Using 5-point scales (0 = poor to 4 = excellent), two radiologists rated the image quality and vessel integrity of bypass for three segments (extracranial, trepanation, intracranial). Results: Image quality was high in both CTA and TOF MRA (mean quality score 3.84 \u00b1 0.37 and 3.8 \u00b1 0.41), without statistical difference (p = 0.66). Mean scores of TOF MRA with respect to bypass visualization were higher than CTA in the intracranial segment (p = 0.026). No significant difference of bypass visualization regarding the extracranial and trepanation segments was found between TOF MRA and CTA (p = 0.66 and p = 0.34, respectively). For the trepanation segment, TOF MRA showed pseudo lesions in 2 of all 25 cases. Conclusions: 3T TOF MRA, a non-contrast technique not exposing the patients to radiation, proved to be at least equal to CTA for the assessment of EC-IC bypass, and even superior to CTA with respect to the intracranial segment. In addition, readers should be aware of a potential overestimation showing focal pseudo lesions of the bypass at the trepanation segment in TOF MRA. <\/jats:p>","DOI":"10.1024\/0301-1526\/a000363","type":"journal-article","created":{"date-parts":[[2014,7,10]],"date-time":"2014-07-10T01:04:57Z","timestamp":1404954297000},"page":"278-283","source":"Crossref","is-referenced-by-count":18,"title":["Assessment of extracranial-intracranial bypass in Moyamoya disease using 3T time-of-flight MR angiography: Comparison with CT angiography"],"prefix":"10.1024","volume":"43","author":[{"given":"Qian","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongfeng","family":"Qi","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoqing","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changsheng","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Jinling Hospital, Medical School of Nanjing University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"101","container-title":["Vasa"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526\/a000363","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,17]],"date-time":"2021-03-17T08:14:00Z","timestamp":1615968840000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526\/a000363"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,6,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2014,6,1]]}},"alternative-id":["10.1024\/0301-1526\/a000363"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526\/a000363","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"value":"0301-1526","type":"print"},{"value":"1664-2872","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,6,1]]}}}
