| Research Abstract |
Two newly-developed dedicated PET scanners (dbPET-C and dbPET-O) are clinically feasible, with sensitivities of 81%(92%) and 84%(95%), respectively, in patient-basis, and 78%(89%) and 81%(92%), respectively, in lesion-basis.(Results after excluding lesions out of scanning range are shown in parentheses) Although superiority of diagnostic performance of these scanners were not demonstrated partly because patients had relatively larger tumors, more precise histopathologic information was provided when lesions were depicted. Further investigations are required to evaluate the quantitative parameters and prognostic values acquired by this modality.
