一次给药做CT增强扫描及静脉肾盂造影两种检查方法

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35例埯行CT增强扫描同时又需行IVU检查者，对其中30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％（34／35），其中在CT机上通过扫定位TOP像的方式模拟进行IVU，成功率达100％（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，减少对比剂用量及其毒副作用。

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

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.
