UF-SPECT was performed 10 minutes before S-SPECT. Images were qualitatively analyzed, and the summed stress score and summed rest score were calculated. The segmental tracer uptake value (percentage of maximum myocardial uptake) also was quantified for both UF- and S-SPECT. When only 29 of 34 patients with significant coronary lesions were analyzed, the summed stress score was 10.1\u00b14.4 versus 6.4\u00b12.9, respectively, for UF- and S-SPECT (\n              <jats:italic>P<\/jats:italic>\n              =0.002). Qualitative and quantitative per-patient analysis showed similar results in detection of coronary artery disease for UF- and S-SPECT. In contrast, per-vessel analysis demonstrated higher regional sensitivity of UF- versus S-SPECT. UF-SPECT showed higher sensitivity in detecting multivessel disease (\n              <jats:italic>P<\/jats:italic>\n              =0.003) versus S-SPECT.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>This pilot study confirms that UF-SPECT provides high-quality fast myocardial perfusion imaging and suggests that it may allow a more-accurate evaluation of both extent and severity of myocardial ischemia in patients with coronary artery disease.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circimaging.110.957399","type":"journal-article","created":{"date-parts":[[2010,11,11]],"date-time":"2010-11-11T03:08:02Z","timestamp":1289444882000},"page":"51-58","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":76,"title":["Comparison Between Ultrafast and Standard Single-Photon Emission CT in Patients With Coronary Artery Disease"],"prefix":"10.1161","volume":"4","author":[{"given":"Alessia","family":"Gimelli","sequence":"first","affiliation":[{"name":"From the Fondazione Gabriele Monasterio (A.
