Abstract

Aiming for robust high-resolution free respiration coronary artery imaging, localized tracking volume selective 3D-EPI at spatial resolution 1.25 x 1.25 x 3 mm and temporal resolution 65 ms was evaluated in 14 normal subjects. Subject-specific motion tracking factors were measured between diaphragmnavigator and coronary artery in S-1 and A-P directions. Imaging was repeated with and without tracking, accepting 128 cardiac cycles over a 20-mm range from free breathing. Reference images with minimal respiratory motion (5-mm rang use LED-guided multiple breathholds. Depending on accurate mo tion measurement, coronary arteries were imaged with tracking, in a 20-mm range of free breathing, with increased scan efficiency but without significantloss of image quality compared to multiple breathhold imaging.
