Spatial Projection Ratio: A Novel Shape Index to Evaluate Aneurysm Rupture Risk Using Three-dimensional Geometry

Spatial Projection Ratio: A Novel Shape Index to Evaluate Aneurysm Rupture Risk Using Three-dimensional Geometry

Shape indices such as size ratio are valuable for diagnosing aneurysm rupture status and may influence rupture risk. However, as these indices are calculated based on two-dimensional measurements, bias may arise from observation directions. To address this, we developed a novel parameter, spatial pr...
