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. 

CT ties steroids, early coronary artery disease in Brazilian population

Brazilian researchers used CT angiography to examine atherosclerosis in individuals who have used anabolic androgenic steroids, finding that the drugs could lead to early onset coronary artery disease.

World's 1st MRI scanner for preemies debuts at Israeli hospital

Shaare Zedek Medical Center in Jerusalem is officially the first hospital in the world to use a newly innovative MRI scanner on premature and newborn infants without having to relocate them outside of the intensive care unit, according to a recent article in Israel's Haaretz.  

Could $10 microchip turn standard ultrasound into 3D imaging technique?

Despite what countless click-bait advertisements may promise, “one simple hack” rarely changes your life. But a new imaging technology from Duke University Health System may pack plenty of potential for changing ultrasonic capabilities.

PET staging charts illustrate Alzheimer's progression, amyloid development

A new study conducted by a team of researchers led by Michel Grothe of the German Center for Neurodegenerative Diseases in Rostock, Germany, announced the development of a four-stage model of regional amyloid beta (Aβ) protein deposition that can be found in patients with Alzheimer's, according to an article by Alzforum. 

Canadian team treating brain diseases with therapeutic ultrasound guided by MRI

An application of MR-guided focused ultrasound (MRgFUS) is showing good promise for treating a number of brain diseases non-invasively and without harming healthy tissue surrounding the target.

Gestational age matters in brain development at birth, but preemies can catch up in childhood

Longer gestation during normal pregnancy is associated with significantly greater development of white matter in babies’ brains. However, similar associations are no longer present by the time children are 8 years old. The lack may confirm that white-matter development in the brains of preemies tends to catch up as these children grow.

FDA greenlights Siemens Healthineers’ 7T MRI for clinical use

In a first, the FDA has cleared a powerful 7-tesla MRI scanner for clinical use.

Wearable MRI still in the works

After leaving high-profile technology jobs with Facebook Oculus and Google X, Mary Lou Jepsen, PhD, resurfaced in September at a wearable-technology conference in Boston. She said her current company, Openwater, is forging ahead with its plan to develop wearable MRI devices that will use holograms to produce better-than-MRI-quality images at a fraction of the cost.

Around the web

RBMA President Peter Moffatt discusses declining reimbursement rates, recruiting challenges and the role of artificial intelligence in transforming the industry.

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.

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease.
