Siemens Healthineers and AI company HeartVista are integrating their individual MR scan sequences into an automated exam protocol designed to enhance the accuracy of cardiac MR and make the exams easier for technologists to perform.
HeartVista is the developer of One Click MR, a multivendor, AI-assisted acquisition software that speeds up standard cardiac imaging by six times and automates complex tasks associated with CMR.
Previously cleared for use on Siemens Healthineers scanners, the two companies have now made the software capable of mixing together sequences from multiple sources using Access-i, a software interface designed by Siemens Healthineers for integrating third-party devices with its scanners.
For those who need to move fast and expand clinical capabilities -- and would love new equipment -- the uCT 550 Advance offers a new fully configured 80-slice CT in up to 2 weeks with routine maintenance and parts and Software Upgrades for Life™ included.
Combining the native sequences of the scanners with One Click MR's built-in ones not only reduces CMR complexity but lengthy periods associated with it as well.
The two hope that together, their technologies will reduce underutilization of CMR, which is a Class I, frontline test for diagnosing chest pain under both American Heart Association (AHA) and American College of Cardiology (ACC) guidelines.
It is considered the gold standard of cardiac diagnostics for all major heart conditions, including ischemic, valvular, myocardial, pericardial and aortic diseases.
"The previous version of our software forced customers to choose between HeartVista’s automated sequences and manual ones that may be more familiar. On that basis alone, we restricted access to the broader market in direct conflict with our mission. Working closely with Siemens Healthineers and implementing the Access-i interface, we have removed a key barrier to market adoption,” said HeartVista CEO Itamar Kandel in a statement.
One Click MR enhances scan accuracy and uses real-time imaging to assess motion and reduce artifacts. This improves image quality by 12%, while the enhanced speed reduces the required number of breath holds in patients.
It also facilitates new registration of perfusion images for easier visual defect detection, enhanced T1-mapping for cardiomyopathy analysis, and dedicated septal T1-mapping for myocarditis.
“With this robust, integrated offering, hospitals can easily select the scan method that works best for them,” said Peter Gall, vice president of magnetic resonance for Portfolio, Partners & Digital at Siemens Healthineers.
