目的 用99TcmO4-动态显像定量分析评价腮腺的分泌排泄功能。方法 给予24例干燥综合征患者和正常对照组44例健康者静脉注射显像剂99TcmO4-,15 min后和口含VitC片0.2 g 5 min后分别摄取腮腺左侧位和右侧位相,将所得的图像通过计算机感兴趣区(ROI)摄取计数处理,以15 min腮腺的总计数减去含VitC后的残余计数再除以15 min的总计数并得到其排泄率(用百分率表示)进行功能性分析。结果 24例干燥综合征组腮腺排泄率有不同程度减低。其中轻度减低2例,中度减低7例和明显减低15例,范围(4.15±3.55)%。对照组44例腮腺排泄率为(41.2±15.9)%。两组比较有显著差异性P<0.001(t=14.6)。表明病变组腮腺排泄率明显低于对照组。结论 腮腺99TcmO4-动态显像定量分析,较准确地反映腮腺的功能状态,具有较高的临床实用价值。 |

Objective To evaluate secretion and excretion function of parotid with the quantitative analysis of 99TcmO4-dynamic imaging. Methods Twenty-four patients who suffered from Sjogren's syndrom (SS) and 44 healthy persons (the control group) were intravenously injected of 185 MBq 99TcmO4-. The left lateral and right lateral images of parotid were acquired 15 minutes after the injection of 99TcmO4-, and 5 minutes after taking 0.2 g Vitamin C tablet under tongue. The absorbed counts of the regions of interest (ROI) of parotids were measured. The excretion rate was (A-B)/A ×100%(A: the absorb counts of parotids at 15th minute; B: the residual counts after taking Vitamin C). Results The parotid excretion rate of 24 patients and 44 healthy persons were (4.15±3.55)% and (41.2±15.9)%, respectively. The difference between them was significant with P<0.001 (t=14.6). Conclusion The quantitative analysis of parotid function with 99TcmO4- dynamic imaging can accurately reflect the function of parotid, so its clinical practical value is fairly high. |
