Peripheral measurement techniques have been the first to be developed for the assessment of osteoporosis, and they remain useful. Besides traditional approaches such as radiographic absorptiometry (RA), radiogrammetry, and single-photon absorptiometry (SPA), new peripheral approaches have been developed that offer powerful ways to assess skeletal status in osteoporosis. These include single x-ray absorptiometry (SXA), peripheral dual x-ray absorptiometry (pDXA), peripheral quantitative computed tomography (pQCT), quantitative ultrasound (QUS) techniques, and magnetic resonance imaging (MRI) approaches. This review describes the current role of peripheral imaging techniques vis-à-vis their central imaging counterparts. Peripheral measurement techniques are attractive because equipment cost is substantially lower, radiation exposure is small, and the devices require less space and sometimes are even portable. Additionally, QUS and MRI offer the potential to measure aspects of bone status beyond the limits of bone densitometry. Peripheral techniques represent important diagnostic methods for the assessment of osteoporosis.
外周测量技术是最早用于评估骨质疏松症的技术，并且至今仍很有用。除了传统方法，如放射吸收法（RA）、放射测量法和单光子吸收法（SPA）之外，还开发了新的外周测量方法，这些方法为评估骨质疏松症的骨骼状况提供了有力手段。这些方法包括单能X线吸收法（SXA）、外周双能X线吸收法（pDXA）、外周定量计算机断层扫描（pQCT）、定量超声（QUS）技术以及磁共振成像（MRI）方法。本综述描述了外周成像技术相对于其中心成像技术的当前作用。外周测量技术具有吸引力，因为设备成本大幅降低、辐射暴露量小，而且设备占用空间较小，有时甚至便于携带。此外，QUS和MRI有潜力测量骨密度测量范围之外的骨状态方面。外周技术是评估骨质疏松症的重要诊断方法。
