Recently, our group reported the preparation and biokinetics and dosimetry of [99mTc]Tc-EDDA/HYNIC-iPSMA ([99mTc]Tc-ethylenediamine-N,N′-diacetic acid (EDDA)/hydrazinonicotinyl(HYNIC)-Lys(Nal)-Urea-Glu) as a radiopharmaceutical with the ability to specifically detect PSMA expression in tumors of prostate cancer by SPECT/CT imaging [8–10]. This evidence concerns the gene FOLH1 and prostate carcinoma.
