帕金森病患者纹状体多巴胺转运体显像与帕金森病临床量表评分的相关性

目的研究帕金森病(PD)患者纹状体多巴胺转运体(DAT)显像与PD临床量表评分的相关性。方法以99mTcTRODAT1为显像剂,用单光子发射断层扫描(SPECT)对29例PD患者进行纹状体DAT显像;应用统一PD评定量表(UPDRS)对患者的运动功能进行评分。将UPDRSⅡ(日常生活活动)、Ⅲ(运动评分)和Ⅴ(病情分期)的评分、患者年龄及病程分别与起病肢体同侧、对侧及两侧纹状体的DAT摄取值进行相关性分析。结果纹状体DAT摄取值与UPDRSⅡ、Ⅲ和Ⅴ评分、病程呈负相关(r分别为-0.70、-0.80、-0.49及-0.54,均P<0.01),与年龄无相关性(r=-0.018,P>0.05);纹状体DAT摄取值与UPDRSⅢ的肌僵直和运动迟缓评分呈负相关(r=-0.782、-0.83,均P<0.01),与震颤评分不相关。结论纹状体DAT显像是反映PD严重程度的客观指标,其与PD临床量表部分项目评分有相关性。

Correlation of striatum dopamine transporter imaging and the scores of Parkinsonian clinical scale in patients with Parkinson's disease

Objective To evaluate the correlation of striatum dopamine transporter (DAT) imaging and the scores of Parkinsonian clinical scale in patients with Parkinson's disease(PD).Methods 99m Tc-TRODAT-1 SPECT imaging was used to assess the DAT binding in the striatums of 29 PD patients, their correlations with the subscales of unified PD rating scale (UPDRS), age and disease duration were also evaluated.Results The scores of subscales of UPDRS II, III and V, as well as the disease duration were negatively correlated with DAT bindings in ipsi-, contra- and bilateral striatum regions (r was -0.70, -0.80, -0.49 and -0.54 respectively, all P<0.01). The scores of rigidity and bradykinesia, but not tremor and age, were correlated with reduced DAT bindings in ipsi-, contra- and bilateral striatum regions (r was -0.782 and -0.83 respectively,all P<0.01).Conclusion Stratum DAT imaging is a reliable indicator of the severity of PD, and it is correlated with the scores of Parkinsonian clinical scale partly.
