From: APIS: a paired CT-MRI dataset for ischemic stroke segmentation - methods and challenges

Examples of images in the APIS dataset. ADC images in axial, coronal, and sagittal planes are displayed in the leftmost columns, while matching views of NCCT images appear in the rightmost columns, both displaying annotations of two experts. The top rows highlight lesions manifesting as hypointense on ADC and hypoattenuated on NCCT. The bottom row presents a case where the lesion is discernible on ADC but less visible on NCCT.
