I have a dataset in which four types of MRI slices are given, i.e T1-weighted, T2-weighted, T1CE images, and FLAIR images. Also, there is a ground truth (segmented) image for each patient to make comparisons between automatically segmented image and manual segmented image done by experts. I got mathematical values of intra-tumorous regions such as edema, active tumor and whole tumor region. But I want to visually represent these three segmented regions just like the SAMPLE IMAGE attached below. How do I make an image in Python such that it shows original MRI brain slices, ground truth slice and segmented MRI slice that can demonstrate MRI segmentation results using my own dataset? I have attached a sample image for better understanding. I dont know how to do this task.
