The aim of this study is to show the advantages of a power injector for contrast media application in comparison to manual bolus injection. The evaluation of 144 studies showed significant improvements for the examinations using the power injector based on densitometry in selected vessels (average enhancement 348 vs 280%) as well as subjective evaluation of contrast quality (3.4 pts vs 2.3 pts on a subjective scale) and contrast-induced artifacts (1.8 vs 2.3 on a subjective intensity scale). All parameters show that an increased, more reliable, and homogeneous enhancement can be obtained by application of the power injector compared to manual bolus injection technique using the same amount of contrast media (100 cc). Due to the possible standardisation of this technique, the results are reproducible. Increased reliability in expected diagnostic gain can be obtained using our technique for intravenous contrast application. This introduced technique requires no additional monetary or time expense and is therefore applicable for clinical routine work.
本研究的目的是展示与手动团注注射相比，使用动力注射器注射造影剂的优势。对144项研究的评估表明，基于选定血管密度测定法，使用动力注射器进行的检查有显著改善（平均增强率分别为348%和280%），以及造影剂质量的主观评估（主观评分分别为3.4分和2.3分）和造影剂诱导伪影（主观强度评分为1.8和2.3）。所有参数均表明，与使用相同剂量造影剂（100 cc）的手动团注注射技术相比，应用动力注射器可获得增强效果增加、更可靠且更均匀。由于该技术可能实现标准化，因此结果具有可重复性。使用我们的静脉造影剂应用技术可提高预期诊断获益的可靠性。这种引入的技术无需额外的金钱或时间成本，因此适用于临床常规工作。
