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.

Brain tumor location has prognostic implications so these authors explored whether location also correlated with p53 status in 182 patients. Tumors occurring in the left medial temporal and right anterior temporal lobes were associated with high expression of mutant p53 and had significantly worse progression-free survival.

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.

Using CT or DWI, the authors categorized percentages of insular ribbon infarctions as less or more than 50% and correlated these with clinical outcomes. Only insular ribbon involvement greater than 50% and low NIHSS score at admission correlated with poor outcomes. They concluded that DWI–percentage insula ribbon infarct of >50% independently predicted poor clinical outcome and can help identify patients with stroke likely to have poor outcome despite small admission DWI lesion volumes.
