MK_I-rim as a radiological feature. We have observed a presence of elevated MK_I values in a rim-like structure that partially circumscribes the tumor (panel A) or its absence (panel B). Yellow arrows mark the MK_I-rim in panel A or tumor region in panel B, respectively. The MK_I-rim is found in the brain tissue surrounding the T1w + Gd enhancing tumor lesion and it was preferentially present in high grade meningiomas. All cases can be found in the supplementary material. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
