how low can we go dose saving through low-dose examination for urolithiasis via modern computer tomography with tinfilter
conclusions modern cts with the innovative technology of a built-in tin filter allow for significant reduction of radiation exposure in patients with suspected urolithiasis by optimizing the x - ray spectrum with image quality as high as in standard ct devices results ct examinations of a total of 143 patients were assessed. dlp of force was 56% and 55% lower in comparison to as+ and flash, (74...
