Apparently, it isn’t just humans who occasionally struggle to work under stress. According to a recent study, the performance of AI flounders, too.

New research could offer further insight into exactly what causes individuals on the spectrum to process information differently.

There have been a total of 11 incidents so far, including seven injuries and two deaths. Boston Scientific said the agent can still be used if operators follow specific instructions during lower GI bleed embolization procedures.

While the latest ChatGPT models show promise in easing the reporting burden on radiologists in the future, they aren't up to the task just yet.

PET brain scan

Fast Track designations are typically granted to drugs that target an unmet medical need.

The recommendations differ between professional medical organizations and contrast manufacturers as well.

In a study, CT-FFR was shown to reduce the need for invasive tests to measure coronary artery blockage from 74.5% to 25.5%.

New artificial intelligence software that can evaluate coronary CT scans to automatically assess soft plaques were by far the biggest technology advance discussed at the Society of Cardiovascular Computed Tomography (SCCT) 2022 meeting.

Experts found that although abbreviated protocols increased the amount of possible scans per hour from 4.7 to 18.8, non-scanning time rose from 50% to 74%.

“For patients with a prior ICM-induced hypersensitivity reaction, healthcare providers must balance the benefit of ICM reuse against the risk of a repeat reaction,” authors of a new meta-analysis published in Radiology said.

Organs

A Canadian manufacturer of positron emission tomography equipment has received FDA’s OK to market a small-footprint scanner that images targeted organs bearing radiotracers at close range.

There have been a total of 11 incidents so far, including seven injuries and two deaths. Boston Scientific said the agent can still be used if operators follow specific instructions during lower GI bleed embolization procedures.  

An independent heart team blinded to ICA results was able to deliver helpful guidance for CABG procedures for 99.1% of patients using just CCTA and FFRCT alone. This approach is safe and feasible, researchers wrote, and the next step is to gather additional data. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
