STREM: a robust multidimensional parametric method to segment MS lesions in MRI

Med Image Comput Comput Assist Interv. 2005;8(Pt 1):409-16. doi: 10.1007/11566465_51.

Abstract

We propose to segment Multiple Sclerosis (MS) lesions overtime in multidimensional Magnetic Resonance (MR) sequences. We use a robust algorithm that allows the segmentation of the abnormalities using the whole time series simultaneously and we propose an original rejection scheme for outliers. We validate our method using the BrainWeb simulator. To conclude, promising preliminary results on longitudinal multi-sequences of clinical data are shown.
