GE HiSpeed NX/i vs HiSpeed CT/e

Given GE’s lead in the US CT scanner market, it’s not surprising that customers who come to us in search of a dual-slice CT often find offerings from GE on their plate. Specifically, most of these customers will, at some point, consider both the GE HiSpeed CT/e (known as the ProSpeed FII in Asian markets) and the GE HiSpeed NX/i.

The oft-asked question is: What’s the difference?

There are actually a number of technical differences when comparing these systems. Before we break down the implications of these differences, however, we’d like to make them plain in the table below:

The Differences:

  GE HiSpeed NX/i GE HiSpeed CT/e
Bore Size 70 cm 65 cm
Tube MHU 3.5 2
Generator 42 kW 24 kW
Gantry Tilt +/-30 degrees +/-20 degrees
Detectors Solid State (HiLight) Solid State (HiLight)
Rotation Time .8 Seconds 1 Second


The Implications:

As for implications, beyond slightly faster scan times and slightly greater flexibility in the scan room via the higher degree of gantry tilt for NX/i users, most of the differences laid out in the table above do not make a significant impact in either direction on the overall image quality or ease of use for these models. 

There are two areas, however, in which the CT/e excels:

  • There are CT/e units available several years newer than the last NX/i units manufactured, increasing the likelihood of finding CT/e machines with low wear and tear.
  • The CT/e's smaller bore uses a lower x-ray dose (up to 33% less) than its 70cm counterparts with no loss of image quality.


The Takeaway:

Both the HiSpeed NX/i and HiSpeed CT/e can serve your dual-slice CT needs very well. In terms of ongoing use, both systems are relatively common and share a good deal of parts crossover, making locating replacements much easier for users of either system. Pricing is also similar between the two. But if reducing the dose your patients receive is important to you, the CT/e emerges as the better system to suit that need.

If you need additional information on the GE HiSpeed CT/e, the GE HiSpeed NX/i, or other dual-slice CT models, contact us to learn more.
