We simulate and experimentally verify SNR improvement from a miniature flexible coil with the ultimate goal to identify microadenomas in the pituitary gland that are currently undetectable. Through scans of a phantom at multiple angles, we show a maximum of 12 to 20 times, and a minimum of 2 to 4 times of SNR improvements compared to the commercial head coil. We also perform high-resolution PD-TSE scans to confirm the visual improvement of our flexible coil.
