Tahara and colleagues performed in vivo and ex vivo SPECT CT in a rabbit and mouse myocardial infarction model and demonstrated uptake of [111In]In-DTPA-GSAO in the same areas of myocardial infarction as [99mTc]Tc-Annexin A5 and found [111In]In-DTPA-GSAO uptake to be more intense than [99mTc]Tc-Annexin A5 [25]. Here, ANXA5 is linked to myocardial infarction.
