A Novel Application of Radiomics Analysis for the Evaluation of Centroid Radii Model Texture on the Surface of Cerebral Aneurysms.

ABSTRACT:

Background

The centroid radii model (CRM)-defined as the distance from aneurysm surface points to the centroid-has shown promise in distinguishing ruptured from unruptured intracranial aneurysms by capturing morphological characteristics. We propose a novel application of radiomics for analyzing CRM texture and patterns, extending radiomics beyond medical imaging-based analysis.

Methods

Three-dimensional rotational angiographic volumes from 187 aneurysms (49 ruptured) were analyzed. Aneurysm surfaces were segmented and converted to uniform triangular meshes. Established size and shape metrics (size, height, aspect ratio, height/width, size ratio, and nonsphericity) and CRM values were computed. CRM data were projected onto a unit sphere and mapped to grayscale images for rad
