RADIATION SIGNS OF LATENT RENAL PARENCHYMA ISCHEMIA IN THE ABSENCE OF LABORATORY CHANGES

Abstract

Latent renal parenchyma ischemia represents an early stage of renal vascular injury in which laboratory  parameters  remain  within  normal  limits.  At  this  stage,  structural  and  hemodynamic alterations precede measurable declines in renal function. Modern radiation-based imaging methods, particularly computed tomography (CT), magnetic resonance imaging (MRI), and functional nuclear techniques, allow detection of subtle ischemic changes in renal parenchyma. This article summarizes the key radiation signs of latent renal ischemia detectable before laboratory abnormalities appear and highlights their diagnostic significance.
