炎性肠病相关骨质疏松的影像学研究进展

Progress of radiological research on osteoporosis related to inflammatory bowel disease

骨质疏松症(OP)是炎性肠病(IBD)病人最常见的肠道外表现之一。双能X线吸收测量仪、CT、MRI以及定量超声等影像方法可以评估IBD病人的骨量、骨结构、骨髓脂肪以及骨强度变化,对IBD的诊断治疗及预后评估具有重要意义。就IBD相关OP的发病机制、影像学研究进展及其临床应用予以综述。

Osteoporosis(OP)is one of the most frequent extra-intestinal manifestations in patients with inflammatory bowel disease(IBD).Some radiological methods such as dual-energy X-ray absorptiometry,CT,MRI,and quantitative ultrasound can be used to assess changes in bone mass,bone structure,bone marrow fat,and bone strength in patients with IBD,which are of great significance for the diagnosis,treatment,and prognosis estimation.The pathogenesis of IBD-related OP,as well as the research progress and clinical application of imaging methods were reviewed.
