MRI of the thoracic spinal cord (t-spine) is challenging especially due to motion, flow, and susceptibility artifacts. Improving the image quality and resolution in t-spine has the potential to improve visualization of anatomy, as well as lesions in neurodegenerative diseases such as multiple sclerosis (MS). Towards this end, we have developed high-resolution t-spine imaging techniques at 7T with a custom built RF transmit-receive coil and navigator based frequency correction.
