甲状腺相关性眼病(TAO)对患者的生活质量、心理健康以及社会经济都造成了严重的负面影响,在该病的早期活动期进行治疗的效果较好,目前该病的活动性分期主要采用临床活动性评分(CAS),其存在较多不足之处。近年来,99Tcm-二亚乙基三胺五乙酸(DTPA) SPECT/CT眼眶显像在TAO的早期诊断、治疗和随访中都显示出重要价值,其可以与CAS互相补充,应用前景广阔。笔者总结了目前该领域的研究进展,提出未来需要更多的研究以期建立标准化的采集和结果分析共识,进一步研究一种新的TAO筛选工具,将99Tcm-DTPA SPECT/CT眼眶显像与人工智能技术相结合,以便更加精准便捷地指导临床。 相似文献

足踝关节复杂的解剖结构给检查带来了较大的困难。目前足踝关节病的初步检查方法是行X线评估,MRI检查则用于进一步明确诊断。99Tcm-MDP平面骨显像对骨代谢的病变具有很高的灵敏度,但由于分辨率低和缺乏解剖结构信息,因而对足踝关节的检查缺乏特异性。99Tcm-MDP SPECT/CT断层骨显像将骨显像的高灵敏度与CT提供的精细解剖结构完美结合,从而更好地显示99Tcm-MDP摄取的位置和解剖结构的改变。近年来SPECT/CT断层骨显像已逐步用于足踝关节病变的辅助诊断。笔者对SPECT/CT断层骨显像在足踝关节病变诊断中的临床应用进行了综述。 相似文献

Objective Through a comparative study of 99Tcm-diethylenetriaminepentaacetic acid (99Tcm-DTPA) and 99Tcm-octreotide (99Tcm-OCT) SPECT orbital scan, evaluated the clinic significance of two imaging of estimation activity in thyroid associated ophthalmopathy (TAO). Methods Aeording to the elinnic activity score (CAS), 26 TAO patients were divided into two groups: active group (CAS ≥3) and inactive group (CAS<3), 14 volunteers (control group) participates this study. Orbit scan were completed after intravenously injection with 99Tcm-DTPA 740 MBq and 99Tcm-OCT (every other day). Obtaining the uptake ratio (UR) of two kinds of orbit scans. The statistical analyses included Paired-samples t test analysis of variance and Spearman regression analysis. Results There is no statistically significance between the two methods in UR (t=0.075, P>0.05). There is a statistically significant correlation was found between CAS and the uptake ratios(99Tcm-DTPA: r=0.835, P<0.001; 99Tcm-OCT: r=0.912, P<0.001). Conclusions There is a good uniformity between 99Tcm-DTPA and 99Tcm-OCT orbital scan; 99Tcm-DTPA is a feasible and maybe a new promising estimation method of activity in the patients with TAO. 相似文献
