Abstract

Abstract:

Objective　To obtain the best vein scanning time of pelvic organs, and high-quality images to provide data for 3D reconstitution. Method Determination of best venous phased scanning time of pelvic CT: 45patients were divided randomly into three groups, 15 in each group, based on different delay time after injection of contrast media, 70s (group A), 90s (group B), 120s (group C). Images were evaluated and graded by two experienced radiologists. SPSS13.0 software was used to process the data. Results In group B, total score was the highest. Statistic analysis of enhanced scanning data revealed that there were significant difference in image quality among the three groups after enhanced scanning and image quality in group B showed best effect of enhancement. Conclusion Delayed time of 90s after injection of contrast media is the best time of venous phased scanning, which provide the best image data for diagnosis of cervical cancer and 3D reconstitution.
