Dɛn na saa nsɛmfua yi PSMA PET kyerɛ?

• PSMA: Eyi gyina hɔ ma `(Prostate-Specific Membrane Antigen)`. Sɛ yɛbɛka no tiawa a, eyi yɛ protein titiriw bi a ɛwɔ prostate kokoram nkwammoaa ani. PSMA yɛ `(Antigen)`, a ɛkyerɛ sɛ ɛyɛ antibody. `(Antigen)` ahorow te sɛ eyi kanyan yɛn nipadua mu ahoɔden a ɛko tia nyarewa no. Nhwɛsoɔ:
