If you've been scanning at a lower slice count, a 64-slice CT represents a powerful step forward for your capabilities. Among the models you're likely to encounter as you begin considering the best 64-slice CT for you is Toshiba's Aquilion 64.
Like many of its contemporaries, the Aquilion offers improvements in image quality, dose reduction, and general workflow. Of course, along with these advantages comes a higher cost that, for some, may be a touch difficult to pay in a lump sum. In situations like these, leasing options from a refurbished equipment vendor can help make it happen.
