<p>Gadolinium-based MR contrast agent is administered to a patient. Acquisition of MR data begins at the latest when the bolus of MR contrast agent reaches the patient's heart and continues throughout the first-pass of contrast agent through the coronary circulation. Advantageously, the acquisition is carried out using a T1-weighted, three-dimensional gradient echo sequence that is synchronized to the patient's cardiac cycle to acquire MR data only during diastole, and a T1-weighting magnetization preparation such as inversion-recovery or saturation-recovery is used.</p> |
