Sažetak

Cilj rada je procena vrednosti scintigrafije pomoću SPECT-a (single photon emission computerized tomography) 99mTc obeleženim eritrocitima u otkrivanju hemangioma u poređenju sa planarnim snimanjem. Planarnom scintigrafijom, senzitivnost metode je 76%, specifičnost 98%, pozitivna prediktivna vrednost 98% a negativna prediktivna vrednost 79%. Primenom SPECT-a senzitivnost metode iznosi 95%, specifičnost 98%, pozitivna prediktivna vrednost 98% i negativna prediktivna vrednost 94%. Najmanja lezija otkrivena pomoću planarne scintigrafije obeleženim eritrocitima iznosi 1.2 cm, a primenom SPECT-a 0.8 cm. Primena SPECT-a povećava senzitivnost više kada su u pitanju manje lezije (0.8 to 2 cm), nego veće (2-5 cm). SPECT pomoću obeleženih eritrocita značajno povećava preciznost scintigrafskog ispitivanja, posebno kod manjih lezija.
