  • 简介:目的探讨脑多巴胺转运体(DAT)^99Tc^m-TRODAT-1SPECT显像与多巴胺D2受体(D2R)^131I-epideprideSPECT显像在早期帕金森病(PD)中的临床应用价值。方法10例正常对照者及46例早期未经替代治疗的PD患者分别接受脑DAT^99Tc^m-TRODAT-1SPECT与多巴胺D2R^131I-epideprideSPECT断层显像,利用感兴趣区技术计算纹状体与枕叶、额叶的放射性比值(ST-OC/OC和ST-FC/FC)。结果PD患者起病肢体对侧脑DAT比值ST-OC/OC和ST-FC/FC比同侧均降低,双侧ST-OC/OC较对照组均降低。PD患者起病肢体对侧脑D2R比值ST-OC/OC和ST-FC/FC比同侧均增高。PD患者起病肢体对侧脑DAT比值ST-OC/OC与患者病程呈负相关,起病肢体对侧脑D2R比值ST-OC/OC与患者年龄及UPDRS运动评分呈负相关。结论人脑DAT^99Tc^m-TRODAT-1SPECT显像与D2R^131I-epideprideSPECT显像均有助于PD的早期诊断及病情监测。
