The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation was developed in an effort to create a more correct formula to estimate GFR, however, it is not able to assess split renal function. Objective. This paper aims to present how numerical analysis of abdominal multispiral computed tomography (MSCT) results correlate with data of CKD-EPI equation. Materials and methods. In this Institutional prospective cohort study, MSCT scans of 16 patients undergoing multiphasic renal protocol with 3D-reconstruction and numerical estimation were reviewed. Comparison was made by means of Pearson coefficient and Youden index. Results. MSCT-based methods for the calculation of split renal function with 3Dmodels showed strong correlation with CKD-EPI (p<0.001). Conclusion. Data received using the 3D-MSCT in comparison with CKD-EPI equation are equally accurate with low bias in GFR-assessment. However new approach has great advantages, because allows for both acquiring detailed data on clinical anatomy and evaluation of renal function, that made it not only precise but also more informative for decision-making in clinical practice. Such application of high-tech imaging method applied to the field of radiology may alter the course of patients' management when pathologic process is just beginning to correct premorbid conditions.
