Coronary magnetic resonance angiography using motion matched acquisition |
摘要 |
Coronary arteries are imaged using a cardiac gated, 3DFT fast gradient recalled echo MRA pulse sequence. A scout scan is performed to measure motion during a cardiac or respiratory cycle and a quiescent period of minimal artery motion is identified. Image data is acquired during a succession of cardiac cycles, and the view order is selected to sample the center of k-space during the quiescent period of each cardiac and or respiratory cycle to reduce motion artifacts.
