Abstract

Quantitative CT (QCT) is a method of measuring bone mineral density (BMD) of human based on a CT machine,calibrated by QCT body model and analyzed by professional software.Compared with dual-energy X-ray absorptiometry,QCT can not only assess the cortical and cancellous BMD but also exclude the influences of osteophytes and aortic/vascular calcification,thus being capable of accurately reflecting patients' bone mass.In recent years,increasing studies on QCT and osteoporosis (OP) have been carried out,and the application of QCT in the diagnosis of OP,evaluation of vertebral bone conditions,prediction of fracture risks,and assessment of anti-OP treatment is garnering increasing attention from researchers at home and abroad.This article reviews the research progress in this field,aiming to provide a reference for the research on QCT in the diagnosis and treatment of OP.

定量CT(QCT)是在临床CT扫描的基础上,经过QCT体模校准和专业软件分析,对人体骨组织进行骨密度测量的方法。与双能X线吸收法相比,QCT不仅能有效区分皮质骨和松质骨,且检测不受骨质增生及血管钙化等因素的影响,可以更好地反映患者骨量情况。近年来,QCT与骨质疏松(OP)的相关研究日益增多,其在OP诊断、评估椎体骨质条件、预测骨折风险及抗OP疗效评估方面的应用不断受到国内外学者的广泛关注。本文总结了该技术在OP诊疗中的应用进展,以期为QCT在OP方面的临床研究提供参考。.
