Core Tip
Core tip: Recent interests have focused on the exploration of the mechanical properties (elasticity, stiffness and deformity) of parenchymatous organs using tissue strain imaging techniques and elastosonography. Many factors can affect measurements and an accurate technique is necessary in order to avoid mistakes and to obtain reproducible data. The use of tissue strain imaging techniques to predict only renal fibrosis or progression of chronic kidney disease is of dubious value because other variables - blood perfusion and urinary pressure - can contribute to a given measure, even with a standardized method able to minimize intra- and inter-operator variability.
