A High Performance Gradient and RF Insert for Dental MRI

Dental MRI requires high resolution imaging, e.g., for detection of root canals, as well as, high readout bandwidth for short T2* tissues, such as dentin and nerve fibers. These requirements can only be satisfied by high-performance gradients. In this study, we show with Bloch simulations the necessity for high performance gradients, and consequently introduce a gradient and RF insert, which is optimized for dental MRI. We also explore the concept a cylindrical encoding for curved slices for 4-fold acceleration compared to conventional encoding.
