A new machine learning approach classifies a common type of brain tumor into low or high grades with almost 98% accuracy, researchers report in the journal IEEE Access. Scientists in India and Japan, including from Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS), developed the method to help clinicians choose the most effective treatment strategy for individual patients.
Gliomas are a common type of brain tumor affecting glial cells, which provide support and insulation for neurons. Patient treatment varies depending on the tumor’s aggressiveness, so it’s important to get the diagnosis right for each individual. Radiologists obtain a very large amount of data from MRI scans to reconstruct a 3-D image of the scanned tissue. Much of the data available in MRI scans cannot be detected by the naked eye, such as details related to the tumor shape, texture, or the image’s intensity. Artificial intelligence (AI ) algorithms help extract this data. Medical oncologists have been using this approach, called radiomics, to improve patient diagnoses, but accuracy still needs to be enhanced.
