The phosphocreatine (PCr) overshoot is a well-documented phenomenon and is readily observable by 31P MRS. In addition, a second 31P MRS observation during ischemia with reperfusion is a diminution in ATP levels. Combining these two as the 'PCr Overshoot' the PCr/ATP ratio may provide an index of viability. However little information is available regarding the duration of this 'overshoot'. For this approach to be useful clinically, the duration of this phenomenon must be ascertained. An open… CONTINUE READING
