摘要
目的观察低剂量CT引导下Hookwire穿刺用于定位体质量指数(BMI)≤22 kg/m^(2)患者肺结节的可行性。方法前瞻性招募53例BMI≤22 kg/m^(2)的肺结节患者(共66枚肺结节)行CT引导下Hookwire穿刺定位,根据CT剂量分为常规剂量组(A组,25例32枚肺结节)及低辐射剂量组(B组,28例34枚肺结节),以B组此前常规剂量CT图像为其对照组(C组)。采用5分制对A、B组CT图像质量进行评分,以3分制评价B、C组图像显示肺结节状态。比较A、B组患者一般资料、肺结节位置、类型、CT值、最大径、图像质量评分、穿刺次数、并发症、容积CT剂量指数(CTDIvol)、剂量长度乘积(DLP)及有效剂量(ED)等,比较B、C组图像显示肺结节评分、结节最大径及CT值。结果A、B组患者一般资料、肺结节位置、类型、CT值、最大径、穿刺次数及并发症差异均无统计学意义(P均>0.05)。B组图像质量评分[4(3,4)]低于A组[5(4,5)](P<0.05)但均≥3分,可满足穿刺定位需求。B组CTDIvol、DLP和ED均低于A组(P均<0.05)。B、C组图像显示肺结节评分、结节最大径、CT值差异均无统计学意义(P均>0.05)。结论低剂量CT引导下Hookwire穿刺可用于定位BMI≤22 kg/m^(2)患者肺结节。
Objective To explore the feasibility of low-dose CT-guided Hookwire localization of lung nodules in patients with body mass index(BMI)≤22 kg/m^(2).Methods Totally 53 BMI≤22 kg/m^(2)patients with 66 lung nodules were prospectively enrolled,CT-guided Hookwire localization of lung nodules were performed.According to the dose of CT scanning,the patients were divided into conventional dose group(group A,25 patients with 32 lung nodules)or low dose group(group B,28 patients with 34 lung nodules),while previous conventional dose CT scanning data of patients in group B were taken as control(group C).The image quality of group A and group B were scored using a 5-point scale,and the displaying of lung nodules in group B and group C were scored using a 3-point scale.The basic information of patients,lung nodules location,type,CT value,the maximum diameter,image quality score,puncture times,complications,as well as volume CT dose index(CTDIvol),dose-length product(DLP)and effective dose(ED)were compared between group A and B,so were score of lung nodules display,the maximum diameter and CT value of nodules between group B and C.Results No significant difference of basic information,the location,type,CT value,the maximum diameter,puncture times of lung nodules nor complications was found between group A and B(all P>0.05).The quality score of group B(4[3,4])was lower than that of group A(5[4,5])(P<0.05)but all greater than 3 and met the needs of puncturing.CTDIvol,DLP and ED of group B were lower than those of group A(all P<0.05).There was no significant difference of the maximum diameter,CT value nor score of lung nodules display between group B and C(all P>0.05).Conclusion Low-dose CT-guided Hookwire localization of lung nodules was feasible in patients with BMI≤22 kg/m2.
