目的：观察低剂量CT扫描在肺部穿刺活检术中的应用，进而探讨其可行性及局限性。方法将100例CT引导下肺穿刺活检患者，用SPSS软件产生随机编号，单数纳入常规剂量组，双数纳入低剂量研究组。常规剂量组50例患者行常规剂量CT扫描（200 mA，重建层厚2．0 mm，螺距16 mm／rot）并穿刺，低剂量研究组50例患者进行低剂量CT扫描（10 mA，重建层厚2．0 mm，螺距23 mm／rot）并穿刺。两组患者经过常规消毒穿刺，取组织样品送病理检查。比较两组CT扫描剂量、图像质量、穿刺成功率及并发症。结果常规剂量扫描组穿刺成功率为90．00％；CT扫描吸收剂量加权指数CTDIw为（23．64±5．91）mgy；平均剂量长度乘积DLP为（172．31±43．08）mgy ×cm。低剂量研究组穿刺成功率为84．00％；CTDIw为（1．22±0．31）mgy；DLP为（8．56±2．14）mgy ×cm。两组的穿刺成功率差异无统计学意义（χ2＝0．6389，P＝0．3742）；辐射剂量差异有统计学意义（CTDIw比较：t＝2．7983，P＝0．0054；DLP比较：t＝2．6849，P＝0．0078）；图像质量分级能满足穿刺活检的需要；同时两组患者均未有严重并发症。结论低剂量较常规剂量CT扫描对肺部穿刺活检成功率无差异，但可显著降低辐射剂量。
目的：觀察低劑量CT掃描在肺部穿刺活檢術中的應用，進而探討其可行性及跼限性。方法將100例CT引導下肺穿刺活檢患者，用SPSS軟件產生隨機編號，單數納入常規劑量組，雙數納入低劑量研究組。常規劑量組50例患者行常規劑量CT掃描（200 mA，重建層厚2．0 mm，螺距16 mm／rot）併穿刺，低劑量研究組50例患者進行低劑量CT掃描（10 mA，重建層厚2．0 mm，螺距23 mm／rot）併穿刺。兩組患者經過常規消毒穿刺，取組織樣品送病理檢查。比較兩組CT掃描劑量、圖像質量、穿刺成功率及併髮癥。結果常規劑量掃描組穿刺成功率為90．00％；CT掃描吸收劑量加權指數CTDIw為（23．64±5．91）mgy；平均劑量長度乘積DLP為（172．31±43．08）mgy ×cm。低劑量研究組穿刺成功率為84．00％；CTDIw為（1．22±0．31）mgy；DLP為（8．56±2．14）mgy ×cm。兩組的穿刺成功率差異無統計學意義（χ2＝0．6389，P＝0．3742）；輻射劑量差異有統計學意義（CTDIw比較：t＝2．7983，P＝0．0054；DLP比較：t＝2．6849，P＝0．0078）；圖像質量分級能滿足穿刺活檢的需要；同時兩組患者均未有嚴重併髮癥。結論低劑量較常規劑量CT掃描對肺部穿刺活檢成功率無差異，但可顯著降低輻射劑量。

Objective To observe the application of low dose CT scanning in lung puncture biopsy,and to discuss the feasibility and limitations.Methods 100 cases of CT guided percutaneous lung biopsy,used SPSS soft-ware to generate random numbers,odd number into the routine dose group,even number into low doses study group. The routine dose group of 50 patients underwent routine dose CT scanning(200mA,reconstruction thickness 2.0mm, pitch 16mm/rot)and puncture,and the low doses study group were given low dose CT scanning in 50 patients (10mA,reconstruction thickness 2.0mm,pitch 23mm/rot)and puncture.Two groups after routine disinfection punc-ture,were taken tissue samples for pathological examination.The two groups of CT scanning dose and image quality, the success rate of puncture and complications were compared.Results The success rate of puncture in conventional dose scan group was 90.00%;CT dose index weighted index CTDIw was (23.64 ±5.91)mGy;the average dose length product DLP was (172.31 ±43.08)mgy ×cm.The success rate of puncture of the low doses study group was 84.00%;CTDIw was (1.22 ±0.31)mgy;DLP was (8.56 ±2.14)mgy ×cm.The successful puncture rate of the two groups had no significant difference(χ2 =0.638 9,P=0.374 2);The radiation dose was statistically significant(CTDIw compare:t=2.798 3,P=0.005 4;DLP compare:t=2.684 9,P=0.007 8);The image quality can meet the need of puncture biopsy;At the same time,the two groups had no severe complications.Conclusion Low dose than routine dose CT scanning in lung biopsy success rate has no difference,but which can significantly reduce the radiation dose.
