股骨头缺血性坏死的临床影像学定量分析技术进展

Progress in quantitative analysis techniques of clinical imaging in avascular necrosis of the femoral head

股骨头坏死的发生发展是一个慢性进行性过程。多年来,研究者致力于在临床上建立一个完善可靠、准确度高、可重复性好的定量研究体系,对股骨头坏死阶段,坏死范围、坏死部位和髋臼受累的情况进行客观评估,同时对不同坏死阶段的预后估计及临床治疗方案的选择进行指导。本文就股骨头缺血性坏死的临床定量研究领域的进展,包括临床影像学技术的综合应用与指标的优化组合,总结国内外的研究成果,为改善股骨头缺血性坏死的研究与防治措施提供科学依据。

Objective The onset and development of necrosis of femoral head is related with slow and progressive process. Over the last few years, a lot of results were reported to set up a scientific quantitative system for evaluation of the stage, area, location, and pathological changes of the acetabulum in osteonecrosis of femoral head as well as estimation of prognosis and direction of treatment. In this paper, the developments in quantitative analysis methods of clinical observation of osteonecrosis of femoral head were summarized, including integration and optimization regrouping of clinical imaging techniques, to provide the scientific basis for improvement of diagnosis and treatment of osteonecrosis of the femoral head.
