The tibial speed of sound (SOS) was measured in 91 healthy singleton infants between 31 and 42 weeks of gestation and 12 sick preterm infants. In healthy infants, the tibial SOS was associated with corrected gestational age (r = 0.40, p < 0.001) but not birth weight. The median tibial SOS in 12 sick preterm infants (2,772, range 2,566-2,934 m/s), whose corrected gestational age was between 31 and 42 weeks, was lower (p < 0.001) than that of 69 healthy gestation-matched healthy infants (3,100, range 2,870-3,381 m/s). Tibial SOS measurements may allow radiation-free assessment of metabolic bone disease of prematurity.
对91名孕龄在31至42周的健康单胎婴儿以及12名患病早产儿测量了胫骨超声速（SOS）。在健康婴儿中，胫骨SOS与矫正胎龄相关（r = 0.40，p < 0.001），但与出生体重无关。12名矫正胎龄在31至42周的患病早产儿的胫骨SOS中位数（2,772，范围2,566 - 2,934米/秒）低于69名与之胎龄匹配的健康婴儿（3,100，范围2,870 - 3,381米/秒）（p < 0.001）。胫骨SOS测量可能有助于对早产儿代谢性骨病进行无辐射评估。
