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.

New cardiac prevention paradigm explored in TRANSFORM trial using AI and CCTA
Deepak Bhatt, MD, director of the Mount Sinai Fuster Heart Hospital and principal investigator of the TRANSFORM trial, explains an emerging technique for cardiac screening: combining coronary CT angiography with artificial intelligence for plaque analysis to create an approach similar to mammography.

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.”

Advanced viz global market to hit $2.8B by 2020

The advanced visualization market, including products for standalone workstations, enterprise-wide software and associated consulting and maintenance, has been projected for a compound annual growth rate of 10.9 percent from 2015 to 2020, reaching $2.8 billion by 2020, according to a new report published by MarketsandMarkets.

Speeding up segmentation

Prior to extended hepatectomy, the tedious process of liver volume assessment must be conducted. Automated and semiautomated liver segmentation methods, however, stand to greatly increase the efficiency of this task, as evidenced by a recent study.

How much does IR improve low-dose CT imaging quality? It depends on the scanner

Iterative reconstruction (IR) makes it possible to reduce radiation dosage without a reduction in imaging quality in low-contrast CT examinations, but its effectiveness varies with different doses and vendors, according to study results published online May 19 in the journal Radiology.

Patient motion during MRI proves to be costly conundrum

When a patient moves during an MRI, it can mean having to redo the scan. Repeated scans take time, and tied up scanners can affect a hospital’s bottom line. Just how costly is patient motion? A recent study from Harborview Medical Center in Seattle pegged the potential cost of motion artifacts at $115,000 per scanner per year.

St. Louis surgical team uses 3D printing to plan toddler’s treatment

When cardiologists from Washington University in St. Louis were preparing to treat a toddler whose heart vessels were located in a position that made it tough for the child to breathe, they didn’t just rely on imaging. In another example of the power of 3D printing, the surgeons created a life-sized replica of the young boy’s heart.
