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.

AI model ‘cuts out the middleman’ to predict knee replacement risk from radiographs

An automated system to predict knee replacement surgery risk is critical, given that more than half of the estimated 14 million Americans suffering from knee osteoarthritis will undergo the procedure.

Measuring 4D flow MRI during exercise offers benefits over stress echo

The approach accurately quantified flow in the ascending aorta and main pulmonary artery and was “highly” repeatable, experts wrote in a pilot study published recently.

Imaging plate technology drops mammography dosage and may be a boon for budget-strapped rad practices

Full-field digital mammography is typically the go-to for many breast imaging centers, but the new approach may prove useful for institutions with smaller budgets.

COVID-19 brain MRI findings reveal three distinct neurological patterns

The French Society of Neuroradiology examined 37 consecutive patients’ neurological imaging findings from 16 different centers for their study published earlier this month.

Refined MRI techniques pinpoint key treatment spot for Parkinson’s disease

Diffusion tractography can help target the specific brain structures neuroradiologists are looking for, with fewer adverse effects.

Around the web

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
