Fig. 7From: Development of a novel imaging system for cell therapy in the brainRepetitive in vivo SPECT imaging of NIS-Hipp-NSCs. a CT scan of the rat head showing the placement of the cannula used to deliver 99mTc into the brain. b SPECT imaging of the brain of a rat that had received 99mTc and no cells. c SPECT signal recorded from the rat brain 2 and 24 h after NIS-Hipp-NSC intracranial injection following delivering of 99mTc. Transverse and coronal slice orientations are shown.
