The latest releases in the MR space focus on speed, ease of use and the patient experience.
For their new MR scanners, OEMs promise smoother patient positioning and workflow, and with software that allows for faster exams without worrying about breath holds or interference from metal artifacts.
In the meantime, coils continue to become lighter and more flexible.

Here’s a look at what’s new.
Canon Medical Systems USA
Last year at RSNA, Canon Medical Systems USA launched a new wide-bore scanner called the Vantage Orian. The 1.5T system comes with workflow tools to help image patients faster.
KneeLine+ performs a quick scan that then helps the technologist with setup, said Jonathan Furuyama, managing director for the MR business unit at Canon Medical Systems USA.
“It is meant to be a tool on the technologist’s side to make scanning a little more robust and repeatable,” Furuyama said.
There are new image acquisition techniques, such as FSE Dixon, which applies a fat saturation technique that allows the technologist to acquire images with or without fat at the same time, while k-t SPEEDER allows up to eight times faster scanning in applications where time is a factor, such as in cardiac imaging.
“Using a tool like k-t SPEEDER can allow the technologist to perform fewer and shorter breath holds,” Furuyama said.
The scanner comes with technologies from previous generation scanners, such as Pianissimo Zen acoustic noise reduction technology and MR Theater, a screen that fits inside the MR bore and uses a mirror to let patients watch during the exam.
The Orian also comes with Canon Medical’s QuickStar free breathing and motion reduction technology.
“It’s a redesign of how MR is done that allows the patient to breathe and also acquires high-resolution scans,” Furuyama said. “If you have to keep holding your breath for 20 seconds every 30 seconds it becomes burdensome on the patient.”
The Orian comes with an optional high-amplitude XGO gradient and added dockable table.
Recently, Canon Medical also debuted its Encore Orian program, which allows the company’s installed base of legacy systems to upgrade the system, building it around the old magnet, which stays in place.
“This gives our customers the option to upgrade to the latest and greatest technology without having to undergo a massive construction project,” Furuyama said.
At last year’s RSNA, GE Healthcare announced AIRx, an AI-based automated workflow tool for brain scans. The technologists select the type of scan and the scanner selects the slice positioning and number of slices to cover the anatomy, providing more image quality consistency between technologists.
