Preventing deadly ruptures of the blood vessels in the brain is the aim of a new Mayo Clinic project to help radiologists detect aneurysms with far greater speed and accuracy. The new method uses analytics technology developed by the Mayo and IBM collaboration, Medical Imaging Informatics Innovation Center and has proven a 95 percent accuracy rate in detecting aneurysms, compared with 70 percent for manual interpretation. Project findings were reported in the Journal of Digital Imaging (published online Nov. 24, 2009).
Already saving patients’ lives, the project has examined more than 15 million images from thousands of patients since the project began in early July. It uses technology that combines advanced imaging with analytics to highlight likely aneurysms for faster detection. This helps radiologists identify them before they result in brain hemorrhage or neurological damage. In the future, Mayo Clinic expects to use the same approach for other radiology detection tests such as the diagnosis of cancer or vessel anomalies in other parts of the body.
“This fully automatic scheme is significant in helping radiologists detect aneurysms in magnetic resonance angiography exams,” says Mayo radiologist Bradley Erickson, M.D., senior author of the study and co-director of the Medical Imaging Informatics Innovation Center at Mayo Clinic.
