T1-weighted spin-echo CE MRI of the heart I a patient with a recent myocardial infarction and currently frequent SVT paroxysms. A - T1-w. SE MRI of the heart, with the axial slice position over the atrium, acquired before injection of paramagnetic contrast. B - T1-w. SE MRI of the heart in the same case, with the same position of the axial slice over the atrium, acquired injection of 15 ml of 0,5M paramagnetic contrast (as 2 ml per 10 kg of BM). The big circle depicts pathologic uptake of contrast to the atrial septum, ostium of the right pulmonary vein and interventricular septum, the little circle depicts the pathologic uptake of contrast to the ostium of the left pulmonary vein.
