Dual-time-point FDG-PET performed better than single-time-point PET in terms of specificity in identifying neoplastic and benign lesions in children, according to a study published in the American Journal of Roentgenology. The dual-point method correctly pinpointed 10 of 13 neoplastic sites and eight of 10 benign sites, the study said. Researchers, however, said the dual-point method may have certain limitations and should be used as a complementary test to standard exams and workup.
