摘要
目的探讨低剂量数字化平板探测器应用于HSG检查的低辐射剂量价值。方法分别对3组HSG检查患者应用普通数字化X线装置、数字化平板探测器及其低剂量模式进行检查,均采用自动曝光控制技术,应用RTI DoseGuard剂量面积乘积仪和RTI WinODS剂量软件检测并计算出每位患者的剂量面积乘积与有效剂量。采用配对t检验比较普通数字化X线装置与数字化平板探测器及其低剂量模式有效剂量的差异性。结果普通数字化X线装置、数字化平板探测器及其低剂量模式的有效剂量分别为3.52mSv、1.26mSv与0.39mSv。数字化平板探测器HSG检查中的辐射剂量约为普通数字化X线装置的1/3,且差异有统计学意义(t=10.85,P<0.01);低剂量模式数字化平板探测器的辐射剂量约为普通数字化X线装置的1/9,且差异有统计学意义(t=17.86,P<0.01)。结论低剂量数字化平板探测器应用于HSG检查具有显著的低辐射剂量优势,能够降低接受HSG检查患者受孕后的出生缺陷率。
Objective To evaluate the value of low-dosage flat panel detector （FPD） for hysterosalplingography. Methods Patients in 3 groups underwent hysterosalplingography using the general digital X-ray device, the digital X-ray device with FPD and it＇s low-dosage mode, respectively. Using RTI DoseGuard and WinODS, the dose area product （DAP） and effective dose of 3 groups were acquired. Auto exposure technique was required. Two independent samples t test was used for the effective dose between the general digital X-ray device and the digital X-ray device with FPD, and it＇s low-dosage mode. Results The mean effective dose was determined to be 3.52 roSy for the general digital X-ray device,1.26 mSv for the digital X-ray device with FPD and 0.39 mSv for it＇s low-dosage mode, respectively. The effective dose of the digital X-ray device with FPD was approximately 1/3 of the general digital X-ray device. The effective dose of the digital X-ray device with low-dosage FPD was approximately 1/9 of the general digital X-ray device. There were significant differences between the general digital X-ray device and the digital X-ray device with FPD, and it＇s low-dosage mode （ t = 10.85, t = 17.86, P 〈0.01）. Conclusion The digital X-ray device with low-dosage FPD has the advantage of low radiation dosage for hysterosalplingography. It will deduce the birth defect of them who had undergone hysterosalplingography.
