The objective is to explore the distribution of 99Tcm-HL91 in cerebral ischaemia animal model and evaluate the 99Tcm-HL91 cerebral ischaemia imaging clinicaly. After animal models were established
99Tcm-HL91 biodistribution was studied by autoradiography. Also
21 patients who suffered from acute cerebral infarction within 96 hours were studied by 99Tcm-HL91 cerebral imaging. Experimental results show that in the ischemic territory more 99Tcm-HL91 accumulated than in the opposite site by autoradiogram. Using computer-enhanced imaging analysis
the optical density (OD) ratio between target and non-target site was significant. In clinical study
8 patients had positive imaging showing accumulation of 99Tcm-HL91 in the surrounding of infarction site. It is concluded that 99Tcm-HL91 can be avidly taken up by cerebral ischemic tissue. 99Tcm-HL91 is a potential agent for imaging hypoxic tissue
and SPECT imaging can be used to evaluate cerebral ischaemia.
