目的探讨多层螺旋CT低剂量扫描在儿童鼻咽部检查中的应用价值。方法将42例患者随机分为两组各21例,在其他扫描参数不变的情况下,A组用100mA扫描,B组用40mA扫描,比较两组图像质量与受检者的辐射剂量。结果两组图像评分均数比较虽有统计学差异,但B组图像评分均数为3.6105,可满足临床诊疗需要;两组腺样体平均CT值之间无统计学差异,CT值标准偏差之间有统计学差异;与A组比较,B组容积CT剂量指数(CTDIvol)和剂量长度乘积(DLP)约降低了60.00%。结论120kV、40mA低剂量儿童鼻咽部CT检查,既能保证图像质量,又有效降低了辐射剂量。
目的探討多層螺鏇CT低劑量掃描在兒童鼻嚥部檢查中的應用價值。方法將42例患者隨機分為兩組各21例,在其他掃描參數不變的情況下,A組用100mA掃描,B組用40mA掃描,比較兩組圖像質量與受檢者的輻射劑量。結果兩組圖像評分均數比較雖有統計學差異,但B組圖像評分均數為3.6105,可滿足臨床診療需要;兩組腺樣體平均CT值之間無統計學差異,CT值標準偏差之間有統計學差異;與A組比較,B組容積CT劑量指數(CTDIvol)和劑量長度乘積(DLP)約降低瞭60.00%。結論120kV、40mA低劑量兒童鼻嚥部CT檢查,既能保證圖像質量,又有效降低瞭輻射劑量。

Objective Multislice CT low-dose scan studies in children nasopharyngeal check the application and its clinical value. Methods Will be 42 patients were randomly divided into A, B two groups, each group 21 cases, under the condition of invariable in other scan parameters, group A with 100mA were scanned, group B with 40mA scanning, compared two groups of image quality and radiation dose of the client. Results Two sets of image scores mean comparison is statistically significant, but group B image scores mean is 3.6105, can meet the needs of the clinical diagnosis and treatment; Two groups of adenoidectomy no statistical difference between the average CT value, CT value was statistically difference between the standard deviation; Group B compared with group A, the CTDIvol volumetric CT dose index(mGy) and dose length product DLP(mGy/cm) reduced about 60.00%. Conclusion 120kV, 40mA low dose children nasopharyngeal CT examination, can guarantee the quality of the image, and effectively reduce the radiation dose.
