目的:探讨低剂量CT扫描技术在脑出血检查中的应用价值。方法对40例脑出血患者行头颅低剂量CT扫描,分析评价其图像质量,记录CT容积剂量指数(CTDIvol),并与传统扫描的辐射剂量进行比较。结果图像清晰无伪影,对比度、分辨率均符合诊断要求;应用低剂量技术,40例患者的平均CTDIvol为37.25 mGy,较传统扫描方式的46.08 mGy,降低约19.1%。结论低剂量CT扫描技术可降低患者的辐射剂量,具有良好的应用前景。
目的:探討低劑量CT掃描技術在腦齣血檢查中的應用價值。方法對40例腦齣血患者行頭顱低劑量CT掃描,分析評價其圖像質量,記錄CT容積劑量指數(CTDIvol),併與傳統掃描的輻射劑量進行比較。結果圖像清晰無偽影,對比度、分辨率均符閤診斷要求;應用低劑量技術,40例患者的平均CTDIvol為37.25 mGy,較傳統掃描方式的46.08 mGy,降低約19.1%。結論低劑量CT掃描技術可降低患者的輻射劑量,具有良好的應用前景。

Objective To explore the application value of low-dose CT scanning technique in the examination of cerebral hemorrhage. Methods 40 patients with cerebral hemorrhage were scanned by low-dose CT. Then the image quality was evaluated and volume CT dose index (CTDIvol) was compared with that of traditional scan. Results The images obtained by low-dose technique were clear without artifacts, and the contrast and resolution ratios were high enough to meet the diagnostic requirements. The average CTDIvol of 40 patients was 37.25 mGy, which lowered about 19.1%than the 46.08 mGy of traditional scan. Conclusion Low-dose CT scanning technique which can reduce the radiation dose of patients enjoys a good application prospect.
