MRI of short T2* samples is possible with ultra-short echo time sequences (UTE) which can be further improved using dedicated RF coils optimized for short-TE imaging. This work compares the performance of a commercial wrist coil with two custom-built coils (birdcage, solenoid) for UTE imaging of a mummy hand (low water content, short T2*), and an in-vivo measurement of a human hand in which short-T2* tissues such as tendons are highlighted by UTE image subtraction.
