Both slice and volume scans were performed to assess relative contributions of T<jats:sub>2<\/jats:sub>* effects, in\u2010flow, and phase\u2010shift effects, specifically within and around the larger vessels (around 1 mm in diameter). The contrast mechanism in single\u2010slice FLASH studies appeared to be predominantly sensitive to in\u2010flow and phase effects of the blood water within these larger vessels, and their relative contributions were dependent on experimental parameters and vascular geometry. The contrast mechanism in gradient echo EPI studies was governed predominantly by T<jats:sub>2<\/jats:sub>* effects in tissue water (and to a lesser extent cerebrospinal fluid) surrounding the larger vessels.<\/jats:p>","DOI":"10.1002\/ima.1850060216","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T23:32:18Z","timestamp":1173137538000},"page":"245-252","source":"Crossref","is-referenced-by-count":9,"title":["Effects of large vessels in functional magnetic resonance imaging at 1.5T"],"prefix":"10.1002","volume":"6","author":[{"given":"Jeff H.","family":"Duyn","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph A.","family":"Frank","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nick R.","family":"Ramsey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venkata S.","family":"Mattay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roy H.","family":"Sexton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathleen A.","family":"Tallent","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel R.","family":"Weinberger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chrit T.
