Abstract: In a method and apparatus for contrast-enhanced magnetic resonance (MR) angiography of the right coronary artery of a patient, a bolus of MR contrast agent is selected to have a size that will cause the bolus, after injection into the patient, to wash out of right coronary chambers of the heart while still enhancing MR signals from the right coronary artery. The bolus of MR contrast agent is injected into the patient, and MR signals are generated in, and MR signals are obtained from, the patient in a time window after the bolus has washed out of the right coronary chambers and still enhances MR signals in the right coronary artery. An MR image of the right coronary artery is generated using only the MR signals obtained in the time window.

Abstract: The present invention relates to a method of perfusion imaging comprising: performing a first magnetic resonance data acquisition (A) at a first sensitivity (b) value, performing a set of at least six second magnetic resonance data acquisitions (B1, B2, . . . B6) with gradiant encodings in different directions at second sensitivity (b) values, determining a perfusion tensor based on the magnetic resonance data acquisitions, performing a perfusion tensor visualitation step.
