A T dispersion imaging method has been successfully developed for human lumbar spine. This technique has potential for detecting proteoglycan loss in the early degenerative disc disease.
Fig. 3: T maps acquired under FSL = 100Hz (A) and 300Hz (B), with TSLs = [1ms, 11ms, 21ms, 31ms, 41ms]. The T dispersion, i.e., T = T(300Hz) - T(100Hz), is displayed in (C).
