摘　　要：目的 探讨自动激光导航引导下行经皮骨髓穿刺活检与CT引导下行徒手经皮骨髓穿刺活检的优劣性。方法 选取2022年1-6月于该院核医学科行骨髓穿刺活检的70例患者为研究对象,根据引导方式的不同分为激光导航组(自动激光导航引导下行骨髓穿刺活检,n=30)和徒手穿刺组(CT引导下行徒手经皮骨髓穿刺活检,n=40),比较两组操作持续时间、辐射总剂量、扫描总次数、骨性病变活检阳性率和穿刺并发症发生情况。结果 与徒手穿刺组比较,激光导航组操作持续时间更短[11.00(7.00,13.00)min vs.13.00(11.00,17.75)min],辐射总剂量更低[439.00(291.00,568.75)mGy vs.510.00(431.25,708.50)mGy],扫描总次数更少[4.50(3.00,6.00)次vs.6.00(5.00,7.00)次],差异有统计学意义(P<0.05)。激光导航组与徒手穿刺组骨性病变活检阳性率比较[96.67%(29/30)vs.85.00%(34/40)],差异无统计学意义(P>0.05)。两组均无穿刺并发症发生。结论 自动激光导航能辅助术者更好地完成经皮骨髓穿刺活检术。Objective To investigate the advantages and disadvantages of percutaneous bone marrow puncture biopsy guided by automatic laser navigation and free-hand percutaneous bone marrow biopsy guided by CT.Methods Seventy patients with bone marrow biopsy at the department of nuclear medicine in this hospital from January to June 2022 were selected as the study subjects and divided into the laser navigation group(bone marrow biopsy guided by automatic laser navigation,n=30)and free-hand puncture group(percutaneous bone marrow biopsy guided by CT,n=40)based on different guidance methods.The duration of the procedure,total radiation dose,total number of scans,positive rate of bone lesion biopsy and puncture complications occurrence were compared between the two groups.Results Compared to the free-hand puncture group,the operation duration in the laser navigation group was shorter[11.00(7.00,13.00)min vs.13.00(11.00,17.75)min],the total radiation dose was lower[439.00(291.00,568.75)mGy vs.510.00(431.25,708.50)mGy],total number of scans was less[4.50(3.00,6.00)times vs.6.00(5.00,7.00)times],and the differences were statistically significant(P<0.05).There was no statistically significant difference in the positive rate of bone lesion biopsy between the laser navigation group and free-hand puncture group[96.67%(29/30)vs.85.00%(34/40),P>0.05].No puncture complications occurred in both groups.Conclusion Automatic laser navigation could assist the operators to better complete percutaneous bone marrow biopsy procedures.
