Low grade glioma segmentation using an automatic computational technique in magnetic resonance imaging
(Sociedad Venezolana de Farmacología Clínica y Terapéutica, 2018)
Through this work we propose a computational technique for
the segmentation of a brain tumor, identified as low grade
glioma (LGG), specifically grade II astrocytoma, which is
present in magnetic resonance images (MRI). This technique
consists of 3 stages developed in the three-dimensional
domain. They are: pre-processing, segmentation and postprocessing.
The percent relative error (PrE) is considered to
compare the segmentations of the LGG, generated by a neuro-
oncologist manually, with the dilated segmentations of the
LGG, obtained ...
