Abstract:
Objective To explore the influence of different injection techniques on the quality of bolus in 99mTc-DTPA renal dynamic imaging.Methods 395 patients accepted 99mTc-DTPA renal dynamic imaging were retrospectively analyzed.All patients were divided into three groups according to injection techniques:direct injection group (187 cases),intravenous route injection group (84 cases)and venous indwelling needle injection group (124 cases).The three groups were injected by each technique.Areas of interest (ROI) were drawn on abdominal aorta by Xeleris workstation in blood flow perfusion imaging.The time-radioactivity curves of ROI were got.The patients whose ROI curve formed a peak was successfully injected,and did not formed was unsuccessfully injected.The number of patients in three groups who were successfully or unsuccessfully injected was respectively calculated.The data of three groups was taken Chisquare test by SPSS17.0 software.Results 174 patients of the direct injection group,46 of the intravenous route injection group and 115 of the venous indwelling needle injection group were injected successfully.The successful rate respectively was 93.0％,54.8％ and 92.7％.The successful rate of the direct injection group and venous indwelling needle injection group were higher than intravenous route injection group.The difference had statistical significance.The successful rate of the direct injection group and venous indwelling needle injection group hadn't statistical significance.Conclusions The successful rates of the direct injection group and venous indwelling needle injection group were similar.The venous indwelling needle injection technique can be chosen.The successful rate of the intravenous route injection group was lower than the other two groups.The intravenous route injection technique should be chosen prudently.
