一次给药做CT增强扫描及静脉肾盂造影两种检查方法

Performance of Enhanced CT scanning and Intravenous Urography by A Single Contrast Administration

目的 探讨一次给药行CT增强扫描及静脉肾盂造影 (IVU)两种检查的可能性、可行性、方法及临床应用。资料与方法 选择 3 5例需行CT增强扫描同时又需行IVU检查者 ,对其中 3 0例利用自制压迫带 ,采用一次给药法先后完成两种检查 ;另 5例则于CT增强扫描结束后 ,在CT机上通过加扫定位TOP像的方式模拟进行IVU检查。结果 通过一次给药先后完成CT增强扫描及IVU检查 ,总成功率达 97.1% ( 3 4/ 3 5 ) ,其中在CT机上通过扫定位TOP像的方式模拟进行IVU检查 ,成功率达 10 0 % ( 5 / 5 )。结论 通过一次给药 ,先后完成CT增强扫描及IVU两种检查 ,可减少患者痛苦 ,缩短各种检查的周期 。

Objective To discuss the feasibility, technique and clinical application of performing enhanced CT scanning and intravenous urography (IUV) with a single administration of contrast.Materials and Methods A total of 35 patients who needed to undergo both enhanced CT scanning and IVU were enrolled in this study. Using a self-made depressing belt and a single contrast administration, the two exams were carried out successively in 30 cases. In the other 5 patients, IVU was performed immediately after enhanced CT scanning with the scanogram manner on the CT table.Results The total successful rate was 97.1% (34/35). The simulant IVU performed with CT scanogram was succeeded in all five patients. Conclusion It is feasible to successively perform CT scanning and IVU with only a single administration of contrast. This technique can relieve patient's pain, shorten the exam time, save the contrast dose and reduce the side effects induced by contrast agent.
