Table 1 Overlap of abnormal ST-ISODATA tissue volumes and ‘Maximal Lesion’ volumes measured using Dice’s Similarity Index

From: Magnetic resonance imaging-based cerebral tissue classification reveals distinct spatiotemporal patterns of changes after stroke in non-human primates

ST-ISODATA input MRI DSI
ADC 0.58 ± 0.39*
FA 0.35 ± 0.24
T2 0.59 ± 0.29*
ADC, FA 0.68 ± 0.32**
ADC, T2 0.60 ± 0.41*
ADC, FA, T2 0.80 ± 0.16**
  1. The combination of ADC, FA, and T2 as input for ST-ISODATA clustering resulted in highest overlap (i.e. highest Dice’s similarity index values) between ST-ISODATA calculated abnormal tissue volumes and ‘Maximal Lesion’ volumes. Therefore this combination was used for ST-ISODATA analysis
  2. DSI Dice’s similarity index
  3. * P < 0.05 versus FA, ** P < 0.001 versus FA
