Flexible form-fitting radiofrequency coils provide high signal-to-noise ratio during MRI, and in array configuration large anatomical areas of interest can be covered. We propose a modular system - “ModFlex”- of flexible lightweight 4-channel coaxial coil arrays for 3T MRI. We investigated the performance difference between commercial reference coils and 8- and 16-channel ModFlex receive-only array systems. The versatility of ModFlex, the robustness of the coil characteristics for different use cases and a signal-to-noise gain compared to reference coils is demonstrated.
