First in vivo results with a modular system of flexible coil arrays for 3 T MRI (ModFlex)

Form-fitting radiofrequency coil arrays have the potential to enhance the signal-to-noise ratio, enable faster imaging and improve patient comfort in MRI. We developed a flexible modular coil array system for 3T MRI (ModFlex) with 16 receive channels. In neck, spine, ankle and hip imaging, we measured an SNR gain for 4 out of 6 anatomical target regions and similar SNR for 2 out of 6 as compared to commercial reference coils. The coil’s versatility is beneficial for different use cases with varying subject sizes.
