Image quality of noninvasive coronary angiography using multislice spiral computed tomography and electron-beam computed tomography: Intraindividual comparison in an animal model

Objective:Comparison of coronary artery visualization by multislice spiral CT (MSCT) and electron-beam CT (EBCT).Materials and Methods:Six minipigs underwent MSCT (collimation 4 × 1 mm, gantry rotation time 500 milliseconds, acquisition time per cardiac cycle 126 ± 30 milliseconds) and EBCT (slice t
