Osteonecrosis, transient osteoporosis, and transient bone marrow edema are closely related diseases that may have an overlapping clinical and radiographic presentation, thus creating difficulty in establishing a diagnosis. Close scrutiny of MR images may aid in distinguishing the pattern of osteonecrosis from other conditions, but in other cases careful clinical and radiologic follow up may be required. The pathogenesis, radiologic diagnosis, and clinical relevance of these conditions are described and reviewed in this article.
骨坏死、暂时性骨质疏松和暂时性骨髓水肿是密切相关的疾病，它们可能有重叠的临床和影像学表现，因此在确立诊断方面存在困难。仔细审视磁共振成像（MR）图像可能有助于将骨坏死的模式与其他病症区分开来，但在其他情况下可能需要进行仔细的临床和放射学随访。本文将对这些病症的发病机制、放射学诊断及临床相关性进行描述和综述。
