AI creates accurate 4D heart scans in seconds

Overall, the group found that its new-look AI model delivered four-chamber evaluations comparable to the work of trained radiologists with “minimal bias.”

“The AI model precisely determined the size and function of the heart’s chambers and demonstrated outcomes comparable to those acquired by doctors manually but much quicker,” Garg said in a prepared statement. “Unlike a standard manual MRI analysis, which can take up to 45 minutes or more, the new AI model takes just a few seconds. This automated technique could offer speedy and dependable evaluations of heart health, with the potential to enhance patient care.”  

Garg et al. noted that they took specific steps to achieve its low levels of bias. For instance, an initial version of their AI model underestimated both left and right ventricular volumes compared to a ground-truth short-axis cine analysis. By applying two correction factors, that “systematic bias” was minimized, leading to much more effective CMR evaluations.
