Artificial Intelligence

Artificial intelligence (AI) is becoming a crucial component of healthcare to help augment physicians and make them more efficient. In medical imaging, it is helping radiologists more efficiently manage PACS worklists, enable structured reporting, auto detect injuries and diseases, and to pull in relevant prior exams and patient data. In cardiology, AI is helping automate tasks and measurements on imaging and in reporting systems, guides novice echo users to improve imaging and accuracy, and can risk stratify patients. AI includes deep learning algorithms, machine learning, computer-aided detection (CAD) systems, and convolutional neural networks.

Why practices might want to think twice before using ChatGPT to create patient education materials

"The potential for disseminating inaccurate information and the occurrence of 'hallucinations'—responses that are generated without grounding in factual data—are significant concerns,” authors of a new analysis warn.

AI decision support tool used in breast cancer screening

Commercially available AI reduces radiologists' workload by 34% in certain screening settings

It also increases cancer detection rates and reduces false positives, according to new work published in the journal Radiology. 

The rapid rise of artificial intelligence (AI) has helped cardiologists, radiologists, nurses and other healthcare providers embrace precision medicine in a way that ensures more heart patients are receiving personalized care.

AI uses imaging results to ID high-risk TAVR patients with speed, accuracy

Researchers developed an advanced AI model capable of extracting measurements from unprocessed CT images in seconds. It then uses those data to evaluate the patient's mortality risk if they underwent TAVR.

Primary care docs lack trust in AI, making it unlikely they'll invest in applications, new survey says

Despite the opportunistic screening capabilities afforded by artificial intelligence applications, primary care providers are hesitant to embrace the technology.  

deep learning algorithm slashes radiation dose during neck CT scans

Deep learning denoising software can cut radiation exposure to 25% of conventional doses during neck CT

And the dose reduction can be achieved without sacrificing image quality, a new analysis shows.

'Too many cooks in the kitchen': How AI is both helpful and a hindrance to radiologists

Recent research suggests that, in many cases, radiologist performance only improves minimally with AI assistance.

Machine learning helps experts identify ADHD biomarkers on MRI scans

Experts have identified numerous white matter features, in addition to changes in white matter tracts that occur over time, which they believe are more common among people with ADHD.

Around the web

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET-CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
