目的探讨在SPECT显像中核素注射技巧与检查质量关系。方法选取2010年7-12月300例骨显像,100例肾脏显像,进行图像分析。结果通过分析我们发现,图像上①1例针头松动导致药品污染病人前臂,10例病人的注射药物外漏,13例按压不足导致出现放射性浓聚,9例留置针冲洗不彻底②动态显像曲线峰值3例出现提前5例滞后和1例药物外漏。结论影响检查质量的因素很多,但常规操作第一步:注射技巧对于整个检查质量有着很重要的作用,如能逐步改善和提高,将对提高整体质量有十分重要的意义。
Objective To investigate the relationship between nuclide injection technique and quality in SPECT imaging. Methods 300 cases of bone imaging and 100 cases of renal imaging from July to December in 2010 were selected for image analysis. Results Through the analysis, we found that 1 case of needle loosening led to drug-induced forearm in 10 cases of patients with drug leakage, 13 cases of under-pressure caused radioactive concentration, and 9 cases of incomplete needle-flushing. The peak of dynamic imaging curve Three cases showed lag in advance of 5 cases and one case of drug leakage. Conclusion There are many factors that influence the quality of the examination. However, the first step in routine operation: the injection technique plays an important role in the quality of the whole examination. If it can be gradually improved and improved, it will be of great significance to improve the overall quality.
