目的 探讨慢性阻塞性肺疾病(COPD)患者进行多层螺旋CT扫描的最适宜剂量.方法 选取90例COPD患者分成常规剂量组和低剂量组,分别进行常规剂量和低剂量扫描,对照分析其影像学质量.结果 90例受检查患者,两种扫描方法均能使影像图质量达到满意要求,且低剂量组辐射剂量明显低于常规剂量组(t=5.01、6.82,均P＜0.05).结论 COPD患者行多层螺旋CT扫描时,低剂量扫描可满足临床诊断要求,又可明显减少对患者的辐射剂量.
目的 探討慢性阻塞性肺疾病(COPD)患者進行多層螺鏇CT掃描的最適宜劑量.方法 選取90例COPD患者分成常規劑量組和低劑量組,分彆進行常規劑量和低劑量掃描,對照分析其影像學質量.結果 90例受檢查患者,兩種掃描方法均能使影像圖質量達到滿意要求,且低劑量組輻射劑量明顯低于常規劑量組(t=5.01、6.82,均P＜0.05).結論 COPD患者行多層螺鏇CT掃描時,低劑量掃描可滿足臨床診斷要求,又可明顯減少對患者的輻射劑量.

Objective To explore the optimum dose of multislice spiral CT scan in the check of patients with chronic obstructive pulmonary disease(COPD).Methods 90 COPD patients were divided into the conventional dose group and low dose group,the quality of conventional-dose and low-dose scan was analyzed respectively.Results The two scanning methods enable images satisfactory requirements in the 90 cases,and low-dose CT radiation dose was significantly reduced(t=5.01,6.82,both P＜0.05).Conclusion For COPD patients using multi-slice spiral CT scan,low-dose scanning can not only meet the requirements of clinical diagnosis,but also significantly reduce the patient radiation dose.
