• Panogona kunge paine kurwadziwa kana kutsvuka payakapihwa tracer.
• Kashoma, allergic reactions kune tracer inogona kuitika, asi kazhinji inenge iri nyore.
• Zvakare, PET scan haizoitwe kuna amai vane pamuviri kana kuti vanoyamwisa.

Ngatizivei nezvemhedzisiro yacho.

Kana mhedzisiro yePET scan yadzoka, nzvimbo dzine mashandiro akawanda emasero dzinoonekwa semavanga akajeka. Izvi zvinogona kuva chiratidzo chechirwere.
