Degenerative
disc disease is an occupational disease of the military pilots, which seriously
influcenes their health and normal
training. Early disc degeneration begins with changes in biochemical
compositions which is mainly characterized by proteoglycan lose and cannot be
detected on conventional MRI imaging[1-2]. T1rho is
a quantitative imaging technique to reflect changes in the extracellular
matrix, such as modifications in the intervertebral disc PG content[3].
In this study，Bivariate correlation
analysis was performed to compare T1rho values to the degenerative grade, disc
space level, age and flight time of the pilots. T1rho values of Lumbar
intervertebral discs in pilots demonstrated significantly negative correlations
with degenerative grade, age and flight time, except for disk space levels. T1rho
can be potentially used as a valid clinical method in the quantitative diagnosis
of early intervertebral disc degeneration in asymptomatic Pilots.
