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.

Sing along with super-fast MRI

A typical MRI scan isn’t able to capture enough frames per second to really see the intricately detailed movements of the dozens of muscles involved in speech or singing. However, a new technique being used at the University of Illinois isn’t your typical MRI scan.

MRI study: Infant brains have similar response to pain as adults

What’s behind those baby blue eyes of infants when they feel pain? Turns out, their still-developing brains are processing pain in a manner similar to adults, according to an MRI study from Oxford University.

Comparing downstream costs: CT colonography versus optical colonoscopy

Colonoscopy has long been the standard when it comes to colorectal cancer screening, but CT colonography has been gaining ground recently as a screening modality due to its less-invasive nature and comparable diagnostic quality. But what difference in costs exists following either CT colonography or optical colonoscopy?

Iterative reconstruction can cut dose, but know the limits

A pair of recent top-read advanced visualization stories focused on studies of iterative reconstruction and how the technology can benefit patients—but it also has its limits.

Tracking low dose performance: How IR impacts low-contrast resolution

Reduction of contrast dosage by 25 percent or more on CT scans results in reduced low-contrast spatial resolution and loss of detection of 6mm nodules on accreditation phantoms using iterative reconstruction (IR) techniques, according to results published online March 26 in the journal Radiology.

Printing in Three Dimensions

When it comes to 3D printing in healthcare, long gone are the days of rustic, stiff protocols that offered more novelty than real-world use.

MRI technique shows potential for prostate cancer detection, treatment

A new MRI technique has demonstrated potential for correcting distortion in prostate cancer imaging, offering a better look at tumor position that could improve treatment planning.

Around the web

RBMA President Peter Moffatt discusses some of the biggest obstacles facing the specialty in the new year. 

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.
