植入的端口系统有效地减少了在动态肝电脑断层扫描 (CT) 扫描期间的对比物质 (CM) 容量和注射速率. 这种方法保持了对比度增强 (CE) 水平,通过减少不适,潜在地提高了患者的舒适度.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 干预性放射学 干预性放射学
背景情况:
- 动态肝电脑断层扫描 (CT) 使用对比物质 (CM) 来增强可视化.
- 评估植入端口系统对CM交付和患者体验的影响至关重要.
研究的目的:
- 为了在动态肝脏CT扫描期间与植入端口系统或没有植入端口系统进行对比,比较对比度增强 (CE) 值,注射率和CM体积.
主要方法:
- 一项涉及169名接受动态肝脏CT扫描的患者的研究.
- 患者被分为两组:传统的CM注射 (87名患者) 和植入端口系统,CM减少20% (82名患者).
- 测量了CE值,注射率和CM体积,并在各组之间进行了比较.
主要成果:
- 在植入端口系统时,没有观察到CE值的显著降低.
- 植入端口系统组显示了减少的注射速率 (2.7 mL/s与3.3 mL/s) 和CM体积 (83.7 mL与103.7 mL).
- 在注射速率和CM体积上,这些减少约为20%.
结论:
- 植入的端口系统在动态肝脏CT扫描期间有效地减少CM体积和注射速率.
- 这种减少在不影响对比度增强的情况下实现,这表明其临床效用.
- 使用植入端口系统可以减轻患者的不适,例如温暖和血管感觉,从而减少患者的负担.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
