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 hos-pital 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 (percutane-ous bone marrow biopsy guided by CT,n=40) based on different guidance methods.The duration of the pro-cedure,total radiation dose,total number of scans,positive rate of bone lesion biopsy and puncture complica-tions 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 differ-ences 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.
