Temporal patterns according to IDH genotype. (A) Graphical definition of the temporal patterns on the heat maps for attention weights overlaid upon T2* susceptibility intensity-time curves according to the segments with the highest and second highest attention weights: if the high attention weights were on segments 1 and 2; segments 1 and 3; segments 1 and 4; segments 2 and 3; segments 2 and 4; and segments 3 and 4 (red), the corresponding temporal patterns were defined as TP 1, TP 2, TP 3, TP 4, TP 5, and TP 6, respectively. (B) The frequencies of the temporal patterns of the heat maps of attention weights according to IDH genotype. The numbers represent percentages.Note: segment 1, pre-contrast baseline; segment 2, downslope of the signal drop; segment 3, upslope of the signal drop; and segment 4, post-bolus plateau.
