Filtered-phase imaging versus susceptibility-weighted imaging for paramagnetic rim lesion detection in multiple sclerosis: A head-to-head comparison

Puntos clave

This research aims to compare the effectiveness of filtered-phase imaging and susceptibility-weighted imaging for detecting paramagnetic rim lesions in multiple sclerosis.
Conducted a head-to-head comparison of filtered-phase imaging and SWI for PRL detection
Assessed inter-rater agreement between evaluators using both imaging techniques
Filtered-phase imaging demonstrated a higher positive predictive value for detecting PRLs
SWI revealed superior sensitivity and inter-rater reliability for PRL assessment

Resumen

Both techniques reliably detect PRLs with substantial inter-rater agreement. Filtered-phase imaging offers superior positive predictive value, while SWI provides better sensitivity and inter-rater reliability. Further development of a standardized training program for assessment of PRL and studies directly comparing susceptibility-sensitive sequences on different vendor platforms are warranted.
