We reviewed the prevalence of avascular necrosis (AVN) in a series of patients with sickle cell disease, using radiography and magnetic resonance imaging. We found AVN of at least one hip in 11 of 27 patients (41%). This is a significantly greater prevalence than reported. MRI was not as helpful in patients with sickle cell disease as it is in patients with AVN from other causes; it detected no more cases than radiography.
我们通过X线摄影和磁共振成像，对一系列镰状细胞病患者的无血管性坏死（AVN）患病率进行了评估。我们发现，27例患者中有11例（41%）至少有一侧髋关节出现AVN。这一患病率显著高于此前报道。磁共振成像在镰状细胞病患者中的作用不如在其他病因导致的AVN患者中那样显著；其检测出的病例数并不比X线摄影更多。
