Toshiba Aquilion 64 vs. GE Lightspeed VCT 64

Toshiba Aquilion 64 versus GE VCT 64.jpg

It's apparent from the start that Toshiba's Aquilion 64 and GE's VCT 64 CT scanners have a lot in common. Both scanners are from leading manufacturers, they're both elligible for reimbursement of cardiac scans in the US, and they're both of similar vintage in terms of manufacturing years. As much as these two systems have in common, however, there are also a number of differences between them that anyone on the market for a 64-slice CT scanner would do well to be aware of.

Below, we'll break down the similarities and differences between the Toshiba Aquilion 64 and the GE VCT 64 as well as highlight the areas in which each of them shines.

What's the same?

There are some features common to both the Aquilion 64 and the VCT 64. These features have such a significant overlap that neither model takes a clear lead in the particular area.

What's different?

The bigger question in comparing the VCT and the Aquilion is learning where they differ. Here are a few of the big things to keep in mind as you compare these two CT models.

Quantum Detector: One clinical differentiator is Toshiba’s Quantum detector. The Quantum offers the thinnest slices in the industry at .5mm. GE detectors employ a .625mm slice thickness. This means that the spatial resolution in the transaxial plane (X-Y plane) and the longitudinal direction (Z direction) are equivalent, giving the Aquilion true isotropic spatial resolution.  

Maximum continuous scan time: The Aquilion has a continuous scan time of 100 seconds, while the VCT tops out at 60.

System Footprint: The VCT 64 is a more compact system and has a smaller footprint overall, installing in 24 meters square. The minimum install area for the Aquilion is 27 meters square.

Tube replacement cost: The Aquilion uses a proprietary tube that is quite pricey to replace. Brand-new from the OEM, buyers can expect to pay $175,000 to $180,000. Buying a VCT tube from the OEM can cost even more than that, however, Varian and Dunlee make VCT-compatible tubes available for as low as $75,000. On the used market, VCT tubes typically cost 25-40% less than Aquilion tubes.

Where the Aquilion Wins

Up-front cost: A Toshiba 64 can be had for around half the price of a GE VCT 64. There is a significant difference in ongoing costs, but in the right capital equipment budget scenario, this can be a compelling point.

Image quality: For the discerning buyer, with specialized needs for the very finest detail and most delicate work, the thinner slices offered by the Quantum detector afford a slight advantage in overall image quality.

Transferability of options: Those purchasing a CT scanner on the secondary market shouldn't encounter any difficulty transferring the software options installed on a Aquilion to their facility along with the equipment. Each successive buyer of a GE machine may come into the need to purchase software licenses.

Where the VCT 64 Wins

XR-29 compliance: For buyers in the US subject to NEMA XR-29 standards, this is an important advantage- all VCT 64 scanners can be made XR-29 compliant at very little cost. This is sometimes the case with the Aquilion, but there are also circumstances where upgrades that cost as much as $75,000 are needed.

Service costs: Because of wider engineer and parts availability, and the aforementioned 3rd-party tube solutions, the ongoing costs of maintaining a VCT 64 are significantly lower than those for maintaining an Aquilion 64.

Availability: While both models discussed here are available on the secondary market, many Aquilion scanners aren't allowed to cross country lines. Because of this the supply of used VCT 64 scanners is ampler.

The Takeaway 

If you are a niche buyer whose workload frequently includes very fine vascular work like coronary exams or thin lung nodule scans, the advantages of the Aquilion 64's Quantum detector may be compelling. For the buyer looking to use their scanner in a more general-purpose fashion, the ability to replace tubes for so much less gives the VCT 64 a major advantage in its overall cost of ownership.
