MAGNETIC RESONANCE IMAGING IN ASEPTIC FEMORAL HEAD NECROSIS

疑似股骨头无菌性坏死的患者 (确诊为镰状细胞性贫血或系统性红斑狼疮 臀部X光正常的红斑症患者接受核磁共振检查， 在CT扫描仪上进行多平面重建(MPR)以确定是否有 新开发的放射学技术比 放射性核素显像在AN诊断中的应用。所有研究，包括 在核医学领域，这些手术是在一周内完成的。 由于进入该方案的标准很严格，只有10名患者 已经入院，目前病人数量太少， 评估一种技术相对于另一种技术的有效性。 这项研究还将提供一种手段来了解 疾病的过程，因为我们计划在6点重复放射学研究 在初次检查后的几个月和一年。

Patients with suspected aseptic necrosis (AN) of the femoral heads (carrying a diagnosis of Sickle Cell Anemia or Systemic Lupus Erythematosus) with normal plain x-rays of their hips undergo MRI and multiplanar reformation (MPR) on the CT scanner to determine whether any of the newly developed techniques in radiology is more sensitive than radionuclide imaging in making the diagnosis of AN. All studies, including those in nuclear medicine, are performed within one week of each other. Since entry criteria into this protocol are strict, only 10 patients have been admitted to it and the number of patients is too small at present to make an assessment regarding the efficacy of one technique over the other. The study also will provide a means to understand the natural history of the disease process, as we plan to repeat the radiographic studies at six months and one year after the initial examinations.
