The signal-to-noise ratio (SNR) within the tibial cortical bone measured by (a) proton density-weighted imaging (PDWI) and (b) sweep imaging with Fourier transform (SWIFT) for the teriparatide (TPTD) and non-TPTD groups. Values are expressed as means ± standard deviations. There was no significant difference in the PDWI-SNR between the two groups at any time point (P = 0.589, 0.394, and 0.394 at 4, 12, and 24 weeks, respectively). The SWIFT-SNR was significantly higher in the TPTD group than in the non-TPTD group at 4 weeks after the initiation of treatment, but no significant difference was observed at 12 and 24 weeks (P = 0.009, 0.937, and 0.818 at 4, 12, and 24 weeks, respectively). *: P < 0.05
