Coronary sinus flow reflects global cardiac perfusion and has been used for the assessment of myocardial flow reserve, which is reduced in chronic heart failure(CHF). Coronary flow reserve (CFR) can be measured by using phase-contrast (PC)velocity-encoded cine (VEC) magnetic resonance imaging (MRI). ⋯ A combined cardiac MRI protocol including function and perfusion techniques together with VEC MRI can be used to evaluate global LV perfusion and CFR in patients with CHF. Global LV perfusion and CFR measurements may have potential in the monitoring of CHF. Impaired CFR may contribute to progressive decline in LV function in patients with CHF.

State-of-the-art magnetic resonance imaging (MRI) protocol for the evaluation of rectal cancer suggests only T2-weighted fast spin-echo sequences. We present a case of rectal cancer with a simultaneous presacral myelolipoma that could have been misdiagnosed on MRI as a metastasis if a T1-weighted sequence had not also been used in the evaluation.
