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.

Cardiology, radiology specialists debate CCTA’s rise as a go-to imaging modality for CAD
CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.
Can large language models break language barriers in radiology reports?
With the growing demand for virtual care and an increasingly mobile population, the need to improve communication with non-English-speaking patients is immense.
Most patients want to know if AI is involved in their care
“With this signal about the public’s preference for notification, the question for health systems and policymakers is not whether to notify patients but when and how.”
New algorithm is twice as accurate at predicting stroke timing compared to the standard of care
Determining stroke onset is critical for management, as there is a small window of time for initiating treatment that can inhibit damage.

Knowledge-based iterative reconstruction enables ultra-low current CT colonography

In a phantom study, reducing tube voltage for CT colonography to 80 kVp cut median effective radiation dose to a level lower than a typical abdominal radiograph, but also resulted in severe deterioration in image noise and per-polyp sensitivity unless paired with a full knowledge-based iterative reconstruction (IR) algorithm, according to findings published July 11 in Radiology.

A good match: Stress DECT myocardial perfusion + coronary CTA for CAD assessment

Combined analysis of coronary CT angiography (CTA) and stress dual-energy CT (DECT) myocardial perfusion reduces the number of false-positives in a high-risk population for coronary artery disease (CAD) and outperforms coronary CTA alone for the detection of morphologically and hemodynamically significant CAD, according to a study published in the July issue of the American Journal of Roentgenology.

Understanding CTC screening

Utilization of CT colonography (CTC) has been increasing as interest grows over the benefits compared with standard colonoscopy. Cost, minimal invasiveness and the fact that it’s well-tolerated by patients makes it an attractive option for most.
