Abstract:
Objective To investigate the effects of different delay time on examination results of patients with suspected cervical cancer after injection of contrast agents.Methods A total of 120 patients with suspected cervical cancer were selected and randomly divided into 20 s group,70 s group,90 s group and 120 s four groups.Patients in four groups were injected with non-ionic contrast agent iohexol(300 mgl/mL)90 mL,and the injection rate was 2 mL/s.Patients in four groups started the scanning at 20 s,70 s,90 s and 120 s after injection,and each group was scanned for 240 s.Arterial developing rate,venous developing rate,the positive rate of detection for cervical cancer,accuracy rate of stage for cervical cancer,and accuracy rate of tumor lymph node metastasis were compared between four groups.Results The results showed that the longer the delay time was,the higher the rate of venous developing was and the lower the rate of arterial developing was,and there were significant differences between the four groups(P<0.05).There was no significant difference in the positive rate of cervical cancer between the four groups(P>0.05).There was significant difference in accuracy rate of stage for cervical cancer between four groups(P<0.05),and there was no significant difference in accuracy rate of tumor lymph node metastasis between four groups(P>0.05).Conclusion Different delay time has affect the results of patients with suspected cervical cancer after injection of contrast agents.
