Single-energy CT predicts uric acid stones with accuracy comparable to dual-energy CT —prospective validation of a quantitative method

ConclusionA quantitative SE-CT method (kNN-ppLapl-maxHU) can classify UA stones with accuracy comparable to DE-CT.Key Points•Single-energy CT is the first-line diagnostic tool for suspected renal colic.•A single-energy CT method based on the internal urinary stone attenuation distribution can classify urinary stones into uric acid and non-uric acid stones with high accuracy.•This immensely increases the availability of in vivo stone analysis.
