The optimal cluster number of FS CE-T1 was 4 (A), and the optimal cluster number of CE-T1 and T2WI was 2 (B,C). The ROI of one patient was grouped into different habitats on FS CE-T1 (D), CE-T1 (E), and T2WI (F), respectively. The red regions correspond to Hab1, green to Hab2, yellow to Hab3, and blue to Hab4.
