title: Abdominal and hepatic uptake of 99mTc-pyrophosphate in neonatal necrotizing enterocolitis.
abstract: Abdominal 99mTc-pyrophosphate (99mTc-PYP) scans were obtained in 15 neonates: 12 with neonatal necrotizing enterocolitis (NEC), two with osteomyelitis, and one with myocarditis. Ten of the babies with NEC had at least one positive scan; of these 10 studies, seven (Group A) showed both diffuse abdominal uptake and localized hepatic activity, two (Group B) showed abdominal uptake and questionable hepatic uptake, and one (Group C) demonstrated diffuse abdominal uptake only. The other two babies with NEC had normal scans (Group D). Pneumatosis intestinalis was unquestionably present in two patients from Group A and one from Group B. Upon resolution of the clinical findings, all NEC patients had normal scans. A patient with myocarditis had hepatic uptake of 99mTC-PYP while the abdominal scan in the two infants with osteomyelitis was normal. These preliminary observations suggest that further study of a relationship between abdominal scan findings and the course of NEC is warranted.
