Abstract：Objective To investigate the clinical application value of three-dimensionally (3D)-mapped puncture biopsy .Methods A total of 104 patients were recruited as the study subjects and were randomly divided in-to two groups.MSCT 3D-positioning and 3D-mapped puncture device were used in the study group , while CT cross-sectional image positioning plus conventional puncture needle was used in the control group .The success rate at one time, repeatedly inserting needle rate , diagnostic accuracy , complication rate and puncture accuracy grading were compared between the two groups .Results The success rate at one time was significantly higher , while the rate of repeatedly inserting needle and complication rate were significantly lower in the study group than those in the control group(P<0.05).In addition, puncture accuracy grading in the study group was also increased significantly than that in the control group ( P<0.01 ) .However , there was no significant difference in the diagnostic accuracy between the two groups(P>0.05).Conclusion Compared with the conventional puncture , 3D-mapped puncture has higher one-time success rate and puncture accuracy grading and lower complication rate .
