Representative 68Ga-NOTA-anti-MMR Nb PET/CT (A) coronal and (B) axial images. In order to validate the results obtained by in vivo PET/CT imaging and to confirm the cardiac origin of the in vivo signal (n = 7), hearts from two MI-induced rats were also scanned ex vivo. (C) Photograph, (D) MRI only and (E) PET/MRI of the representative heart excised from rat, 7 days after coronary ligation, confirmed an augmented 68Ga-NOTA-anti-MMR Nb uptake in the area close to the ligation site. 68Ga-NOTA-anti-MMR Nb exhibited elevated uptake in scars from operation (blue arrowheads).
