Gaussian-fitted
histogram analysis of T2 relaxation time could achieve quantitative measurement
of the distinction between the
nucleus pulposusand anulus fibrosus, and Gaussian-fitted histogram
parameters have good performance in diagnosing and staging disc degeneration.
Figure.1 T2 histograms and Gaussian distributions of AF and NP.
a-e: Pfirrmann grade I-Ⅴ discs. The peak value of the NP gradually decreased and shifted towards the peak of the AF with the increasing grades.
f: The peak value of the NP was significantly lower than the AF of grade Ⅳ disc.
Figure.3 Receiver operating characteristic (ROC)
curves analysis of all
quantitative parameters
for distinguishing healthy discs from degeneration ones.
