在活体中传播的纵波的声速（SOS）反映了组织特性，并且被期望作为用于疾病检测、诊断和监测的有前景的评估指标。但是，由于SOS受压缩性和多种因素的影响，其解释一般比较复杂。在本研究中，作为SOS解释的研究，通过使用超声和磁共振成像（MRI）的融合在体内测量软骨的SOS，并研究SOS与其他量之间的相关性。总之，作为本研究中使用的软骨组织SOS的一种可能解释，认为SOS部分与含水量有关。
The speed of sound (SOS) of a longitudinal wave propagating in the living body reflects the tissue properties and is expected as a promising evaluation index for detection of disease, diagnosis and monitoring. However, in general, the interpretation of SOS is complex, because it is influenced mostly by compressibility and multiple factors. In this study, as a study for the interpretation of SOS, the SOS of cartilage was measured in vivo by using a fusion of ultrasound and magnetic resonance imaging (MRI), and the correlations between the SOS and other quantities were investigated. In summary, as a possible interpretation of SOS of cartilage tissue used in this study, it was suggested that the SOS was partly related to water content.
