Reply to 'In vivo imaging of islet transplantation'

Frantisek Saudek , Peter Girman , Jan Kriz , Daniel Jirak & Milan Hajek

To the editor: In vivo visualization of transplanted pancreatic islets might advance islet transplantation as treatment for diabetes, helping to confirm technical success and diagnose rejection. Evgenov et al. described a method of labeling human islets with a superparamagnetic contrast agent and the subsequent detection of the islets using magnetic resonance imaging after transplantation into the liver or the renal subcapsular space in mice.
