Repeatability of outpatient head CT interpretations performed in an academic practice was assessed in 119 randomly selected studies. These were blindly read twice by 8 neuroradiologists. Differences in location and severity of findings occurred in 9.2% of cases and contradictory findings in 15.1%. Thus, discrepancies in double-blind interpretations were more common than reported in peer-review quality assurance programs.

Double inversion recovery was used to study 30 patients with suspected or established MS and images were blindly evaluated by 2 neuroradiologists. DIR detected 28% more lesions than T2-weighted images with higher contrast-to-noise ratios leading to increased rating in lesion visibility. The authors concluded that the DIR sequence allowed better detection of lesions in MS and related inflammatory diseases of the cervical spinal cord compared with conventional T2WI.
