| 摘 要： | 目的：探讨低剂量CT扫描对青少年副鼻窦疾病的应用价值。方法：对35例青少年副鼻窦疾病患者分别行低剂量和常规剂量扫描,对比两种剂量扫描所得图像质量与患者的辐射剂量。结果：低剂量和常规剂量扫描两种扫描方法所显示的图像质量没有显著差异（p〉0.05）,低剂量CT扫描单次扫描的辐射剂量加权指数（CTDIvol）为7.6mGy,常规剂量的为28.1mGy,两种扫描方法辐射剂量有显著差异（p〈0.01）。结论：低剂量CT扫描在副鼻窦疾病中是可行的,能保证图像的质量,又有效的降低患者的辐射损伤。

| Abstract: | Objective： To ebaluate the diagnosis of imaging and preventive value of low dose MSCT scanning in paranasal sinus examination. Methods： 35 patients of paranasal sinus were scanned with low dose and with conventional dose. To analys them quality of image and dose of radiation. Results： There was no signiticant difference in low dose CT scanning and conventional one, the sigle scanning~CT dose inder weighted of the low（CTDIvol） wer 7.6mGy, and the one of conventional was 28.1mGy. Conclusion： It＇s provide assurane of quality of image in low dose CT scanning and reduces exposure of patients and hazards of exposure. |
