الوصف:	Background Aneurysm wall enhancement has been identified as a potential biomarker for aneurysm instability. Enhancement has been determined by different approaches on 2‐dimensional multiplanar views. This study describes a new method to quantify enhancement through 3‐dimensional (3D) heatmaps and histograms. Methods A custom algorithm was developed using orthogonal probes extending from the aneurysm lumen into the wall to create 3D heatmaps and histograms of wall enhancement on 7T magnetic resonance imaging. Three quantitative metrics for general, specific, and focal wall enhancement were generated from the histograms. Results Thirty‐two aneurysms were analyzed and classified based on 3D heatmaps and histograms. Larger aneurysms were more enhancing (Spearman r=0.472; P=0.006) and had more heterogeneous enhancement (Spearman r=0.557; P
