Although postcontrast imaging has been used for many years in musculoskeletal imaging, dynamic contrast enhanced (DCE) MRI is not routinely used in many centers around the world. Unlike conventional contrast-enhanced sequences, DCE-MRI allows the evaluation of the temporal pattern of enhancement in the musculoskeletal system, perhaps best known for its use in oncologic applications (such as differentiating benign from malignant tumors, evaluating for treatment response after neoadjuvant chemotherapy, and differentiating postsurgical changes from residual tumor). However, DCE-MRI can also be used to evaluate inflammatory processes such as Charcot foot and synovitis, and evaluate bone perfusion in entities like Legg Calve Perthes disease and arthritis. Finally, vascular abnormalities and associated complications may be better characterized with DCE-MRI than conventional imaging. The goal of this article is to review the applications and technical aspects of DCE-MRI in the musculoskeletal system.

尽管对比后成像在肌肉骨骼成像中已经使用了多年，但动态对比增强（DCE）MRI 在世界上许多中心并未常规使用。与传统的对比增强序列不同，DCE-MRI 允许评估肌肉骨骼系统中增强的时间模式，其在肿瘤学应用中最为人所知（例如，区分良性和恶性肿瘤，评估新辅助化疗后的治疗反应，以及区分术后变化与残留肿瘤）。然而，DCE-MRI 也可用于评估炎症过程，如夏科足和滑膜炎，并评估佩特兹病和关节炎等实体的骨灌注。最后，DCE-MRI 可能比传统成像更好地描述血管异常和相关并发症。本文的目的是回顾 DCE-MRI 在肌肉骨骼系统中的应用和技术方面。
