Adenosine stress perfusion (stress study A-C, rest study D-F) MRI in a 81 year old patient with increasing dyspnoea. Stress-induced perfusion deficits septal in the basal (A) and mid-ventricular (B) segments without correlate during resting conditions (D-F). Conventional angiography revealed a hemodynamically relevant (fractional flow reserve <0.8) stenosis in a septal coronary artery branch.
