@uclaradiology.bsky.social researchers & colleagues validate MRI-derived maps predicting tumor cell density in brain gliomas. Using image-guided biopsies, these maps correlated with true cellularity in treatment-naïve patients, supporting non-invasive surgical planning.
Independent histological validation of MR-derived radio-pathomic maps of tumor cell density using image-guided biopsies in human brain tumors - Journal of Neuro-Oncology
Purpose In brain gliomas, non-invasive biomarkers reflecting tumor cellularity would be useful to guide supramarginal resections and to plan stereotactic biopsies. We aim to validate a…
