ViCOROB (Girona) wins a competition for automatically detecting lesions of multiple sclerosis
| Published by University of Girona
Researchers of the Computer Vision and Robotics Institute (ViCOROB) of the University of Girona (UdG) obtained the best results in the international competition entitled "MS segmentation challenge using a data management and processing infrastructure". The competition consisted in the development of automated tools to aid in the detection and segmentation of multiple sclerosis lesions on magnetic resonance imaging. The event took place in Athens, Greece, in the framework of the 19th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI 2016).
The purpose of the two proposals submitted in the challenge was to obtain software tools applicable to clinical practice in both specialised units in multiple sclerosis and generic radiological centres. The tools automatically analyse the images taken with MRI to identify the lesions which are characteristic of the disease, to determine the degree of cerebral atrophy of the patients, and also to facilitate the measurement and the assessment of changes over time. In the future, this technology will be used in an objective and automatic monitoring of the effects of the different treatments in multiple sclerosis patients.
The database of images that was used in the competition contained data from 38 patients from four different centres and scanners. Each patient's injuries were manually annotated by a group of seven experts. During the competition the objective was to assess both the detection of lesions (the overall number of detected lesions per patient) and the segmentation of lesions (the degree of precision that each lesion is delimited). The tools presented, which provided the best results in both detection and segmentation of lesions, are the result of research carried out in the projects BiomarkEM.cat and NICOLE, funded by Fundació La Marató de TV3 and the Spanish Ministry of Economy and Competitiveness, respectively.
The ViCOROB team was formed by researchers Sergi Valverde, Eloy Roura, Mariano Cabezas, Sandra González-Villà, Xavier Lladó, Arnau Oliver, Joaquim Salvi and Jordi Freixenet, in collaboration with radiologists and neurologists from the University Hospital of Girona Dr. Josep Trueta, the Hospital Parc Martí and Julià (Salt), the Multiple Sclerosis Center of Catalonia (CEMCAT), the Vall d'Hebron University Hospital, the Institute of Biomedical Research of Girona (IdIBGi) and the Vall d'Hebron Research Institute (VHIR).
