Images from a variety of anatomic regions in healthy volunteers were calculated with either an MIP procedure alone or with data that had first been processed with the CVA. A low\u2010signal\u2010intensity threshold is first applied to separate groups of voxels associated with different vessels from one another and to eliminate the contribution from low\u2010intensity stationary material. The remaining voxels are grouped by a connectivity criterion into discrete \u201cobjects.\u201d Vessels are represented by extended objects, and small objects are discarded. The CVA, therefore, reduces the full three\u2010dimensional data set into a small number of discrete objects. It is a powerful technique that can be used to remove signal from vessels overlying the vessel of interest, to separate objects representing arterial flow from those representing venous flow, to eliminate flow artifact from projection images, and to more completely retain signal within the vascular lumen. This technique has been successfully demonstrated with MR angiography in healthy volunteers.<\/jats:p>","DOI":"10.1002\/jmri.1880010406","type":"journal-article","created":{"date-parts":[[2007,3,6]],"date-time":"2007-03-06T01:37:33Z","timestamp":1173145053000},"page":"423-430","source":"Crossref","is-referenced-by-count":11,"title":["Application of a connected\u2010voxel algorithm to MR angiographic data"],"prefix":"10.1002","volume":"1","author":[{"given":"David","family":"Saloner","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William A.","family":"Hanson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jay S.","family":"Tsuruda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rem","family":"van Tyen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles M.","family":"Anderson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ralph E.","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,17]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.171.3.2717754"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.171.3.2717755"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.175.3.2343137"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.173.2.2798885"},{"key":"e_1_2_1_6_2","first-page":"170","volume-title":"Book of abstracts: Society of Magnetic Resonance in Medicine 1990","author":"Napel S","year":"1990"},{"key":"e_1_2_1_7_2","first-page":"193","volume-title":"Proceedings of the IEEE Computers in Cardiology Conference","author":"Rossnick S","year":"1986"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.154.3.2106232"},{"key":"e_1_2_1_9_2","first-page":"488","volume-title":"Book of abstracts: Society of Magnetic Resonance in Medicine 1990","author":"Saloner D","year":"1990"},{"key":"e_1_2_1_10_2","first-page":"489","volume-title":"Book of abstracts: Society of Magnetic Resonance in Medicine. 1990","author":"Hu X","year":"1990"},{"key":"e_1_2_1_11_2","first-page":"491","volume-title":"Book of abstracts: Society of Magnetic Resonance in Medicine","author":"Lakshminarayanan AV","year":"1990"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0730-725X(87)90124-X"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.176.3.2389051"}],"container-title":["Journal of Magnetic Resonance Imaging"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjmri.1880010406","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jmri.1880010406","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,23]],"date-time":"2023-10-23T15:39:52Z","timestamp":1698075592000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jmri.1880010406"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,7]]},"references-count":12,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1991,7]]}},"alternative-id":["10.1002\/jmri.1880010406"],"URL":"https:\/\/doi.org\/10.1002\/jmri.1880010406","archive":["Portico"],"relation":{},"ISSN":["1053-1807","1522-2586"],"issn-type":[{"value":"1053-1807","type":"print"},{"value":"1522-2586","type":"electronic"}],"subject":[],"published":{"date-parts":[[1991,7]]}}}
