Rein 3D PRINT MECHANICS
Multimodal Imaging of the Biomechanical Properties of Kidney Tumors: Feasibility, Inter-modality Correspondence and Diagnostic Value
Source: ClinicalTrials.gov · Last updated 14 Apr 2026
Brief summary (registry, in English)
The goal of this innovative project is to evaluate the correspondence between several imaging modalities for characterizing the elasticity of healthy and pathological renal tissue which could help improve the realism of 3D prints used by urological surgeons and allow the identification of new, complementary imaging biomarkers. The main objective is to develop a predictive model of the biomechanical properties of normal and pathological kidney tissue, as assessed by the reference method (Magnetic Resonance (MR)-elastography).
