現(xiàn)在可以使用Stellant CT注射系統(tǒng)用于冠狀動(dòng)脈的計(jì)算機(jī)X線斷層掃描，該系統(tǒng)產(chǎn)生的人工假象較少。該設(shè)備由Medrad公司(Indianola, PA, USA)研制成功，設(shè)計(jì)用來滿足最新的臨床需要；該系統(tǒng)使用安全便于操作，能夠滿足快速CT掃描的需要。配備DualFlow選擇模式的Stellant D，通過同步活塞運(yùn)動(dòng)模式產(chǎn)生不同比例，允許同時(shí)進(jìn)行對比顯像和注射生理鹽水。通過使用適當(dāng)?shù)谋壤蜁r(shí)間控制，就能夠均一地顯示右側(cè)和左側(cè)心室。

該設(shè)備同時(shí)還具有如下特點(diǎn)：壓力監(jiān)測圖、設(shè)計(jì)改良過的注射器、自動(dòng)加藥注射、以及從單次注射升級至兩次注射的能力。

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.
