3T MRI texture analysis using the polar Stockwell Transform (PST) was applied to 15 new acute T1 black holes (BHs) at baseline from 9 multiple sclerosis (MS) patients. PST texture was calculated for each pixel of lesional ROIs and 9 NAWM regions. Texture spectrum differed between lesions and NAWM. The low frequency energy was higher and span broader in persistent BHs than in transient BHs (P < 0.05). These results suggest that the PST texture analysis may have the potential to predict trueBH from tranBH at the time of lesion formation, months before visible evolution.
