FIG 1. Graphic representation of the probability distribution of cystic intracranial lesions being clustered around the center of two groups: free water-like and non-free water-like–filled lesions. The x axis indicates the distance of each case from the center of each of the two groups. The y axis represents the contrast resolution between CSF and cystic intracranial lesion content. The z axis represents the probability of being clustered in one of the two groups. As the distance from the center of one of the two clusters increases, the probability coefficient decreases.
A, Calculated on T1-weighted images (R-T1).
B, Calculated on T2-weighted images (R-T2).
C, Calculated on PD-weighted images (R-PD).
D, Calculated on FLAIR images (R-FLAIR).
