Preamplifier decoupling has been used to isolate elements of receive array coils for decades. For good SNR, decoupling of elements is essential. However, recent research results claim that this just holds for “real” electromagnetic decoupling rather than preamp decoupling as long as the SNR-optimal channel combination is used. We performed experiments on the impact of preamplifier decoupling including also accelerated imaging using SensE. We found no significant difference in SNR between preamplifier decoupled and resonant coil elements.
