Quantification of CBF requires knowledge of the arterial input function (AIF), which is usually provided by arterial blood sampling. However, arterial sampling is invasive. Moreover, the blood generally is sampled at the wrist, which does not perfectly represent the AIF of the brain, because of the effects of delay and dispersion. We developed and validated a new noninvasive method to obtain the AIF directly by PET imaging of the internal carotid artery in a region of interest (ROI) defined by coregistered high-resolution magnetic resonance angiography. An ROI centered at the petrous portion of the internal carotid artery was defined, and the AIF was estimated simultaneously with whole brain blood flow. The image-derived AIF (IDAIF) method was validated against conventional arterial sampling. The IDAIF generated highly reproducible CBF estimations, generally in good agreement with the conventional technique.\n                  <\/jats:p>","DOI":"10.1038\/jcbfm.2012.143","type":"journal-article","created":{"date-parts":[[2012,10,17]],"date-time":"2012-10-17T04:05:37Z","timestamp":1350446737000},"page":"115-121","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":44,"title":["Noninvasive Estimation of the Arterial Input Function in Positron Emission Tomography Imaging of Cerebral Blood Flow"],"prefix":"10.1177","volume":"33","author":[{"given":"Yi","family":"Su","sequence":"first","affiliation":[{"name":"Department of Radiology, Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana M","family":"Arbelaez","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Washington University School of Medicine, St Louis, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tammie LS","family":"Benzinger","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abraham Z","family":"Snyder","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrei G","family":"Vlassenko","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark A","family":"Mintun","sequence":"additional","affiliation":[{"name":"Avid Radiopharmaceuticals, Philadelphia, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcus E","family":"Raichle","sequence":"additional","affiliation":[{"name":"Department of Radiology, Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,10,17]]},"reference":[{"key":"bibr1-jcbfm.2012.143","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000177884.72657.8b"},{"key":"bibr2-jcbfm.2012.143","first-page":"177","volume":"25","author":"Mintun MA","year":"1984","journal-title":"J Nucl Med"},{"key":"bibr3-jcbfm.2012.143","first-page":"790","volume":"24","author":"Raichle ME","year":"1983","journal-title":"J Nucl Med"},{"key":"bibr4-jcbfm.2012.143","doi-asserted-by":"publisher","DOI":"10.1002\/nbm.1075"},{"key":"bibr5-jcbfm.2012.143","doi-asserted-by":"publisher","DOI":"10.1038\/jcbfm.1987.85"},{"key":"bibr6-jcbfm.2012.143","doi-asserted-by":"publisher","DOI":"10.1038\/jcbfm.1987.97"},{"key":"bibr7-jcbfm.2012.143","doi-asserted-by":"publisher","DOI":"10.1007\/BF01728767"},{"key":"bibr8-jcbfm.2012.143","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.188.1.8511286"},{"key":"bibr9-jcbfm.2012.143","doi-asserted-by":"crossref","unstructured":"Croteau E, Lavall\u00e9e \u00c9, Labbe S, Hubert L, Pifferi F, Rousseau J,  Image-derived input function in dynamic human PET\/CT: methodology and validation with 11C-acetate and 18F-fluorothioheptadecanoic acid in muscle and 18F-fluorodeoxyglucose in brain.
