Unicancer 2020 award, 6th edition

 

link of unicancer

Aim of the project:
Our project is to develop an application that will enable the evaluation, in a multicenter, of radiomic or AI models proposed for the management of lung cancer patients. Multicenter validation of models remains indeed essential to consider their clinical use.

Methods:
This application will actually be a new module added to LIFEx, a software we are developing, to easily describe a radiomic model. As for any module of this application, the libraries used will guarantee that the application remains free and autonomous (i.e. without installation of third party software). Interfacing with the ConSoRe platform, which is a Unicancer's Big Data platform, will later make it possible to combine features extracted from medical images and text included in the medical reports.

Impact:
The main benefit will be to give medical teams a tool to evaluate radiomic and AI models on their own data, using models that have already been published or developed by colleagues. This large-scale, multicenter validation step provides information on the reliability and robustness of the models and is absolutely essential for clinical translation.

Problem to be solved:
If the field of radiomics and AI in radiology and nuclear medicine is growing exponentially, the current major bottleneck is the difficulty to validate the many published models in order to establish their performance and clinical added value. Our project will make this evaluation possible in an independent way, via a public software guaranteeing the transparency of the results.

Target users:
Our project will serve both the current users of LIFEx (10 Unicancer centers already use LIFEx, the 3600 users worldwide, including more than 700 in France) and future LIFEx users, given that we have about 100 new users every month. These are mainly radiologists, nuclear physicians, researchers and engineers involved in medical image analysis.

Introduction

Texture analysis is gaining considerable interest in medical imaging, in particular to identify parameters that might characterize tumor heterogeneity. We developed an easy-to-use freeware enabling calculation of a broad range of conventional, textural and shape indices from PET, MR, US and CT images.  

The software is written in Java and does not rely on any commercial libraries. LIFEx is dedicated to researchers, radiologists, nuclear medicine physicians and oncologists that giving access to 42 histogram, textural and shape indices in addition to conventional indices and where users can change calculation options (e.g. resampling method and number of grey levels for textural analysis).
