Abstract:
Objective To investigate the impact on image quality of bone imaging and patients safety when whole body bone imaging was performed on the sme day of renal dynamic imaging.Methods Fifty-three adult patients underwent renal dynamic imaging and whole body bone imaging were selected as observation group.Firstly,99 Tcm-DTPA renal dynamic imaging was performed,and 2 h later,99Tcm-MDP was injected,then whole body bone imaging was performed according to technological process.The other 53 patients received bone imaging only were selected as control group.After injection of 99Tcm-MDP immediately and 30 min,1 h,2 h,4 h,6 h,and 24 h later,physiological response of all patients was observed,and image quality of bone imaging between the two groups was compared.Then the ratio of subjective excellent images of the two groups was calculated.Radioactivity counting of T12,L4,iliac crest,middle humerus,middle femur and soft tissue above 2 cm of ilium on posterior image was measured,and target/non target (T/NT) was calculated.Statistical analysis was performed on the two groups.Results Adverse reaction was not found in all patients in two groups.Subjective excellent rate was 90.57％ (48/53) in observation group,and 92.45％ (49/53) in control group (x2 =0.12,P＞0.05).T/NT of T12,L4,middle humerus and middle femur had no significant differences between two groups (all P＞0.05).The difference of T/NT of iliac crest was statistically significant between two groups (t=3.45,P＜0.05).Conclusion Radionuclide renal dynamic imaging on the same day has no significant impact on the image quality of whole body bone imaging.
