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.

Combining automated tools decreases CT radiation dose

Combining automatic tube voltage selection (ATVS) with automatic tube current modulation (ATCM) significantly decreases the radiation dose from abdominal and thoracic contrast-enhanced CT scans compared with ATCM alone, according to a study published in the August issue of the American Journal of Roentgenology.

3D CT offers effective, noninvasive tool for pulmonary hypertension

Normal lung volume as measured with computer-aided 3D quantitative analysis of chest CT correlates with mean pulmonary artery pressure as measured by right heart catheterization in pneumonia patients, making CT an attractive, noninvasive alternative for predicting pulmonary hypertension, according to a study published in the August issue of American Journal of Roentgenology.

Now you see it: Tracking eye gaze during CTC interpretation

Using a desk-mounted tracker to follow the gaze of radiologists as they interpreted 3D CT colonography (CTC) videos revealed that other than time to first pursuit, visual search pattern metrics don’t vary significantly between experienced and inexperienced readers, according to a group of U.K. researchers.

Making CT colonography better

Two of our top stories from the past month dealt with research to make CT colonography (CTC), an already attractive option compared to standard colonoscopy, even better. One dealt with an algorithm to aid in the detection of polyps, while the other investigated a technique to reduce tube voltage that cut radiation doses to a level lower than a typical abdominal radiograph.
