Human cardiac 31P magnetic resonance spectroscopy at 3T with a receive array: is single-loop or dual-loop RF transmission superior?

Journal article

Abstract:: Human cardiac phosphorous MR spectroscopy (31P-MRS) provides direct insight into cardiac energetics by measuring concentrations of ATP, ADP, phosphocreatine (PCr) and other species. Yet at 3T, excitation flip angles in the inferior segments of the myocardium have been limited to be much less than the "Ernst angle" needed to maximise spectral SNR. This has made it impossible so far to acquire spectroscopic images that cover the whole heart, which in turn has limited 31P-MRS to the study of diffuse rather than focal disease. In this study, we test whether splitting the RF transmission between anterior and posterior coils improves spectral quality across the myocardium compared to transmission from the anterior side alone.
