Machine-Learning Algorithm Analyzes Images to Identify Schizophrenia Patients

A team of researchers from the University of Alberta has developed a machine-learning algorithm to examine functional magnetic resonance imaging (fMRI) images for identifying patients suffering from schizophrenia and ascertaining if they would respond to treatment. In a study, the algorithm examined MRI images of both newly diagnosed, previously untreated schizophrenia patients and healthy subjects and successfully identified patients with schizophrenia at 78% accuracy. It also predicted whether or not a patient would respond positively to a specific antipsychotic treatment named risperidone with 82% accuracy. More...

NIH Releases Huge Database of CT Images for AI Testing

The National Institutes of Health’s Clinical Center has made a large-scale dataset of CT images available to the public in order to help the scientific community improve the detection accuracy of lesions. The dataset, named DeepLesion, has over 32,000 annotated lesions identified in CT images, as compared to less than a thousand lesions in most of the publicly available medical image datasets. The images are of 4,400 unique patients, who are partners in research at the NIH and have been completely anonymized. In 2017, the NIH clinical center had released anonymized chest X-ray images and their corresponding data. More...
