This study examines the possibility of coronary artery fly-through using a dataset obtained by noninvasive coronary angiography with contrast-enhanced electron-beam computed tomography.\n <\/jats:p>\n \n Methods and Results<\/jats:italic>\n \u2014Ten patients were examined, and 40 to 60 transaxial tomograms (thickness, 1.5 mm; in-plane pixel dimensions, \u22480.5\u00d70.5 mm) were obtained after intravenous contrast injection. The datasets were processed on a graphics workstation using volume-rendering software. For fly-throughs, the contrast-enhanced lumen was made transparent and other tissue was made opaque. Then, key frames were selected in a path through the vessel, with software interpolation of frames between key frames. A typical movie contained 150 to 300 frames (10 to 15 key frames). Fly-throughs of coronary bypass grafts (n=3), left anterior descending arteries (LAD; n=6), and the intermediate branch (n=1) were reconstructed. Coronary calcifications were seen in 3 patients. The fly-through of the intermediate branch, the bypass grafts, and one of the LADs did not show any irregularities. In 2 cases, a stenosis was visible in the LAD; its presence was confirmed by conventional coronary angiography.\n <\/jats:p>\n \n Conclusions<\/jats:italic>\n \u2014Recent developments in fast-volume rendering using special-purpose hardware in combination with noninvasive coronary angiography with electron beam computed tomography have provided the possibility of performing coronary artery fly-throughs.\n <\/jats:p>","DOI":"10.1161\/01.cir.102.1.e6","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:42:29Z","timestamp":1339461749000},"update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":13,"title":["Coronary Artery Fly-Through Using Electron Beam Computed Tomography"],"prefix":"10.1161","volume":"102","author":[{"given":"Peter M.
