Solution Overview

Problem

Current methods for detecting tumor enlargement in low-grade gliomas lack a universally accepted objective technique, relying on subjective visual comparison of longitudinal radiological studies, leading to delayed detection and variable treatment outcomes.

Innovation Solution

A computer-assisted diagnostic method using image segmentation and the online abrupt change-of-point analysis to determine tumor volume changes from sectional images, providing an objective and timely assessment of tumor growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

AI summary

A method and computer-based system is provided that assists physicians in detecting early tumor growth, for example, glioblastoma (GMB) and low-grade gliomas, and allowing modification of treatment to have a positive impact on medical management, patient morbidity, outcomes and survival times. The method comprises measuring tumor volumes from radiological images to predict growth by a statistical method. The methods allow detection of increases in tumor size earlier than is currently possible and, therefore, advantageous in modifying or optimizing treatment.
