Machine learning software can easily gauge brain atrophy

Artificial intelligence can quickly and accurately rate the amount of atrophy in parts of the brain, which can help in the diagnosis and research of dementia. A new study reported in arXiv.org, It is an inexpensive way to quantify brain atrophy and helps improve the specificity and sensitivity of diagnosis. These visual atrophy ratings aren't used widely because the ratings are inherently subjective, researchers note. Radiologists performing them need to be experienced in such work, and the assessments are tedious and time consuming--it takes several minutes per image for a neuroradiologist to perform the rating. And while the rating is potentially useful in a clinical setting, the current process does not easily enable the study of larger groups of images, which is important for research purposes.
