Coronary CT Angiography Without R-Blockers

摘要

The goal in cardiac imaging is to optimize the timing of the physical image acquisition with the physiologic motion of the heart. Ideally, one would match the fastest available imaging with the slowest available heart motion. Advances in MDCT technology allow faster image acquisition l> 82.5 milliseconds with dual-source CT) [1-4] or greater coverage (15 cm with 256-detector-array CT) so that an entire coronary data set can be acquired in one heartbeat.
