The localization of yttrium loaded radioembolization microspheres and the detection of their effects on structural and functional integrity of the tumors remain a challenge. In the present work, the mechanical properties of the glass substrate of the microspheres was exploited in applying MR elastography sequence on a phantom and on a hepatocellular carcinoma patient.
