Medrad公司的CT注射系统显著提高心血管影像检查的质量

现在可以使用Stellant CT注射系统用于冠状动脉的计算机X线断层扫描，该系统产生的人工假象较少。该设备由Medrad公司(Indianola, PA, USA)研制成功，设计用来满足最新的临床需要；该系统使用安全便于操作，能够满足快速CT扫描的需要。配备DualFlow选择模式的Stellant D，通过同步活塞运动模式产生不同比例，允许同时进行对比显像和注射生理盐水。通过使用适当的比例和时间控制，就能够均一地显示右侧和左侧心室。

该设备同时还具有如下特点：压力监测图、设计改良过的注射器、自动加药注射、以及从单次注射升级至两次注射的能力。

CT Injection System Improves Cardiac Images
 
Improved computed tomography (CT) of the coronary arteries is now possible with fewer artifacts with the Stellant CT injection system. The device, developed by Medrad (Indianola, PA, USA), is designed to meet the latest clinical, safety, and ease-of-use requirements of rapidly evolving CT technology. The Stellant D with the DualFlow option enables both contrast and saline injection at the same time through variable ratios of simultaneous plunger motion. With the proper ratio and timing, right and left heart ventricles can be illuminated uniformly.

The device also features a pressure monitor graph, improved syringe design, syringe autoload, and the ability to upgrade from single to dual injections.
