T1rho imaging is a new MRI sequence for cancer evaluation but the repeatability of this sequence in the head and neck region is unknown. T1rho imaging of the head and neck was performed three times comprising an initial scan (scan 1) followed by a scan 30 minutes (scan 2) and 14 days (scan 3) later. The repeatability, agreement and variance for the parotid gland, palatine tonsil and tongue were assessed by comparing scan 1 and 2 and comparing scan 1 and 3. Results suggested that T1rho imaging could be a reliable sequence for use in the head and neck.
