Summary : Stress cardiovascular magnetic resonance (CMR) allows for the detection of myocardial ischaemia with no radiation to the patient, either through the use of pharmacologic stress (adenosine, dipyridamole) first-pass perfusion CMR, or through dobutamine-atropine stress cine CMR for the assessment of abnormal segmental LV function. Stress CMR has excellent diagnostic accuracy compared to scintigraphy and echocardiography, and allows for the evaluation of location and extent of myocardial ischaemia, with obvious prognostic implications. The detection of myocardial ischaemia is part of a comprehensive CMR study, allowing for the detailed study of morphology, global and segmental LV function, and myocardial viability. Stress CMR is a very useful method for the detection of myocardial ischaemia, especially in various situations for which treadmill test is doubtful, impossible, sub-maximal or when ST segment cannot be reliably assessed. |
