A comparison of exogenous and endogenous <scp>CEST</scp><scp>MRI</scp> methods for evaluating in vivo p<scp>H</scp>

Abstract

Measurements of k_ex with endogenous CEST MRI cannot substitute for pHe measurements with acidoCEST MRI. Whereas endogenous CEST MRI may still have good utility for evaluating some specific pathologies, exogenous acido-CEST MRI is more appropriate when evaluating pathologies based on pHe values.
