GE HealthCare Launches AI-Powered Prostate Volume Assist for Ultrasound
An emerging artificial intelligence software may enable clinicians to quickly obtain automated measurements of prostate volume.
With the launch of Prostate Volume Assist, clinicians can ascertain prostate measurements and calculations with one click, according to GE HealthCare, the manufacturer of the software. The company said the Prostate Volume Assist can be beneficial with prostate imaging and ultrasound-guided procedures.
“Normally, clinicians determine prostate volume through a manual, repetitive process that requires measuring multiple dimensions and applying a mathematical formula,” said Fredrik Gran, head of innovation, surgical visualization and guidance, ultrasound at GE HealthCare. “Prostate Volume Assist uses artificial intelligence to automate this process with a single click, and yield results in less than two seconds. This technology provides an added level of support for (clinicians) to improve efficiencies in the workflow and enable precision care.” (Read More at DiagnosticImaging.com)
FDA Clears New 7T MRI System from Siemens Healthineers
The Magnetom Terra.X., a new 7T magnetic resonance imaging (MRI) system, has garnered 510(k) clearance from the Food and Drug Administration (FDA). A second-generation successor to the Magnetom Terra, the Magnetom Terra.X system has a number of attributes to provide enhanced 7T imaging, according to Siemens Healthineers, the manufacturer of Magnetom Terra.X.

More MRI techs needed to combat wait times as burnout figures rise, association says
Funding commitment must be part of upcoming provincial budget, group says
The association representing medical radiation technologists says more MRI technologists are needed in the province to combat wait times.
In January the median wait time for an MRI at three Winnipeg hospitals was 30 or more weeks, according to data from the province’s wait time dashboard.
Dayna McTaggart, the provincial manager for the Canadian Association of Medical Radiation Technologists (CAMRT), calls the numbers startling.
“It’s a lot of pressure put on the MRTs because we feel a sense of responsibility for it,” McTaggart said.
“We don’t want patients to wait longer than they have to. We’re contributing to the burnout of ourselves by wanting the best for our patients and continuing to take overtime shifts in order to fill [voluntary] night shifts … to get patients the scan they need quicker.”
The province’s wait time dashboard shows in January of this year people needing an MRI were looking at a median wait time of:
- 35 weeks at the Grace Hospital.
- 37 weeks at Health Sciences Centre.
- 30 weeks at the Children’s Hospital.
MRI method purported to detect neurons' rapid impulses produces its own misleading signals instead
A new way of imaging the brain with magnetic resonance imaging (MRI) does not directly detect neural activity as originally reported, according to scientists at MIT’s McGovern Institute. The method, first described in 2022, generated excitement within the neuroscience community as a potentially transformative approach. But a study from the lab of McGovern associate investigator Alan Jasanoff, reported in the journal Science Advances, demonstrates that MRI signals produced by the new method are generated in large part by the imaging process itself, not neuronal activity.
Jasanoff explains that having a noninvasive means of seeing neuronal activity in the brain is a long-sought goal for neuroscientists. The functional MRI methods that researchers currently use to monitor brain activity don’t actually detect neural signaling. Instead, they use blood flow changes triggered by brain activity as a proxy. This reveals which parts of the brain are engaged during imaging, but it cannot pinpoint neural activity to precise locations, and it is too slow to truly track neurons’ rapid-fire communications.
