Well the article says that each slice is 600 microns apart so definitely smaller than a typical human CT that I’ve worked with where each slice is at least 1 mm apart. Also, the contrast is very high which means higher radiation does per slice is needed. In human context, like others have stated in this thread, if you don’t need a higher resolution then don’t order one. But sometimes, you only know if some areas needed higher resolution after you’ve seen the result. And the radiation dose for an additional, higher resolution and smaller areas might be much greater than just capturing the original CT with higher resolution.

> Well the article says that each slice is 600 microns apart so definitely smaller than a typical human CT that I’ve worked with where each slice is at least 1 mm apart. I’ve just checked our PACS. The extremity protocols are at .6mm, face at .75mm and spine is 1mm. It was .6mm 10 years ago when I ran them at other sites, so I don’t think this is anything pioneering. You possibly do the same, but we generally reconstruct thicker. 1mm acquisitions reconstructed in another plane at 1mm look a bit gross as the acquisition needs to be thinner than the recon. The dose is not high on modern equipment.
