Pediatric Radiology 2007;37:1201-8.
We sought to evaluate observer variability among experienced neurosonologists. We collected all protocol US scans of 1,450 infants born before the 28th postmenstrual week. Each set of scans read by 2 sonologists for presence of IVH and mod/sev vmeg, & EL &EG: in WM. Scans read discordantly sent to a tie-breaking third sonologist.
Vmeg, EL and IVH had similar rates of positive agreement (68-76%), negative agreement (92-97%), and kappa values (0.62 to 0.68). EG had lower values of positive agreement (48%), negative agreement (84%), and kappa (0.32).
