A Combined Ultrasonic Backscatter Parameter for Bone Status Evaluation in Neonates

Figure 2

The scatterplots of AIB (a-c), SCS (d-f), and CAS (g-i) associated with gestational age at 3.5 MHz, 5.0 MHz, and 7.5 MHz (n = 505). Gestational age is negatively correlated with SCS (|r| = 0.52 – 0.57, P < 0.001), and positively correlated with AIB (|r| = 0.39 – 0.58, P < 0.001) and CAS (|r| = 0.63 – 0.68, P < 0.001).
