“…Taken together, these results suggest that CMR spectroscopy can provide metabolic evidence for myocardial viability (Bottomley and Weiss, 1998). In early cardiac allograft rejection, decreased PCr/ATP ratios are seen (Canby et al, 1987;Fraser et al, 1990), although this must be distinguished from transient reductions early after transplantation that might occur on the basis of transient allograft ischaemia. In LV hypertrophy, the PCr/ATP ratio is generally normal (Pluim et al, 1996), but reductions are seen in hypertrophic cardiomyopathy (Jung et al, 1998;Rajagopalan et al, 1987).…”
