Paper Abstract

Twelve radiologists each reviewed a randomly selected mixture of 50 pairs of conventional radiographic images (CRI) and contrast-enhanced digital radiographic images (CEDRI) of neonates with either necrotizing enterocolitis (NEC) or no suspected intra-abdominal abnormality (normal controls). Each image was rated as to overall suspicion of NEC. The data for the NEC and control groups were analyzed and compared to a multiple-review "gold standard" as determined by an experienced pediatric radiologist. For both the CRI and CEDRI, the radiologists tended to underrate the suspicion of NEC in those neonates with NEC and overrate the suspicion of NEC in the control neonates without NEC. Digital manipulation of the original CRI resulted in an increased sensitivity but decreased specificity for the radiographic diagnosis of NEC.
