In recent years, CT-scan has become an important diagnostic imaging modality for patient management in Emergency Department (ED). In response at this development, GE Healthcare has designed scanners with high flexibility, speed and accuracy diagnostic capabilities enabling doctors to deliver a fast therapeutic strategy. 

What are the specific needs in the Emergency Department  

In the Emergency Department, patients come in with various sorts of diseases, like chest pains, multiple fractures, hemorrhages or ischemia, that need to be quickly imaged, rapidly diagnosed and routed towards the right departments for the most serious cases. Depending on pathologies, the challenges can be different and specific for each indication.

Discover how University Hospital Donostia and
Jena University Hospital improved their ED practices

Jena University hospital in Germany that upgraded their emergency department (ED) with a RevolutionCT and ASiR-V1, GE’s blended Iterative Reconstruction algorithm. Empowered by these technologies, the clinic has created a new set of clinical protocols called “the Big Five” that combine stroke and chest pain management in the ED to further enhance patient care and increase clinical confidence. 

Unicersity Hospital Donostia in Spain installed RevolutionEVO and ASiR-V to increase efficiency and accuracy in CT scans while lowering dose for thousands of stroke and polytrauma patients each year.


1. In clinical practice, the use of ASiR, ASiR-V and Veo may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. ASiR-V low contrast detectability (LCD), image noise, spatial resolution and artifact were assessed using reference factory protocols comparing ASiR-V and FBP. The LCD measured in 0.625 mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using model observer method.

ASiR-V is available for Revolution EVO, HD & CT.
