【摘要】 目的探讨Fahr病的CT和MRI影像学表现与诊断价值。方法分析8例经临床证实的Fahr病的CT、MRI资料,并结合文献讨论该病的诊断和鉴别诊断。结果影像学表现为双侧基底节区、丘脑、小脑齿状核、大脑灰白质交界区广泛且较对称的钙化;实验室检查患者的血清钙、磷及甲状旁腺素指标均正常。结论CT可以清晰地显示钙化病灶的大小范围。在显示钙化方面,MRI不如CT敏感,但梯度回波可改善这种状况,且能显示病灶内和周围胶质增生的范围及程度。CT和MRI结合对Fahr病的诊断起了协同作用,而血清钙、磷及甲状旁腺素水平正常是Fahr病与其他疾病鉴别的关键指标。更多还原

【Abstract】 Objective To investigate the imaging findings and the diagnostic value of CT and MRI of Fahr disease.Methods To analyzed the CT and MRI data of 8 cases clinically proved Fahr disease.The diagnosis and differential diagnosis of this disease were compared with the literatures.Results The imaging examination demonstrated that Fahr disease mainly presented the bilateral and symmetrical calcification in the basal ganglia areas,thalami,dentatum and subcortex.The levels of serumal calcium,phosphorus and parathormone were normal in the laboratorial examination.Conclusion CT can clearly display the sizes and scope of the calcified lesions which is more sensitive than MRI,but MRI can utilize the gradient echo to improve it.Furthermore,MRI can show the range and extent of the gliosis.CT and MRI play a coordinate role in diagnosing Fahr disease.,while the normal levels of serumal calcium,phosphorus and parathormone are the critical indices for differentiating Fahr disease form other diseases.更多还原
