AI can diagnose heart disease in four seconds
New research has found that artificial intelligence can spot heart problems with similar precision to experts in a fraction of the time.
Published in the journal Circulation: Cardiovascular Imaging, the research found that artificial intelligence was 186 times faster than humans at reading cardiac MRI scans, potentially saving the equivalent of 54 clinician-days per year at each cardiac centre in the UK.
It is estimated that around 150,000 cardiac MRI scans take place in the UK each year. The scan, which typically takes a human around 13 minutes to complete, informs a number of important treatment decisions, including the safe use of chemotherapy and the timing of cardiac surgery.
Charlotte Manisty, senior author of the study, said: “Cardiovascular MRI offers unparalleled image quality for assessing cardiac structure and function, however current manual analysis remains crude. Automated machine learning techniques offer the potential to change this and radically improve efficiency, although demonstrating superiority over human observers has yet to be shown.
“Our dataset of patients with a range of cardiac diseases scanned twice enabled us to demonstrate that the greatest sources of measurement error arise from human factors, and that automated techniques are at least as good as humans, with the potential soon to be ‘super-human’ - transforming clinical and research measurement precision.”
The research was supported in part by a grant from Barts Charity.

Their concern rose with discovery the flame retardant paints most widely used paint along escape routes have been ones which to this day counter-productively use emission of heavy toxic gas to smother flames which rapidly spread along walls if layers of paint delaminate in a fire.
