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-produced CT biomarkers predict heart attack, death—topping traditional risk scoring

The heart-based risk information was taken from colorectal cancer screening exams and beat out the Framingham risk score and body mass index.

Multimodality imaging uncovers ‘landmarks’ for peripheral arterial disease recovery

These new recovery milestones will allow clinicians to pinpoint whether or not a patient is responding to therapy or making the necessary strides toward rehabilitation.

Radiologists identify second type of schizophrenia, challenging conventional knowledge

The discovery came after researchers combed through hundreds of brain scans and found that nearly 40% of patients did not have the reduced gray matter volumes typically seen in those with the disorder.

Blood travels differently through women’s and men’s hearts, 4D MRI shows

This information can help clinicians adjust the quantitative standards used to asses how a patient's heart is functioning.

AI’s ‘extra set of eyes’ helps radiologists identify missed intracranial hemorrhage cases

“Given the potential impact diagnostic errors can have on patient outcomes, new AI tools and technology that can assist radiologists may be of great value as clinicians strive to continuously decrease error rates and improve patient care,” researchers wrote in Academic Radiology.

Advanced imaging confirms cooling therapy targets brain’s core in newborns

Babies who suffer from a lack of oxygen are often treated using whole-body cooling in order to save brain tissue, but until now it's been difficult to determine how this therapy actually impacts the organ.

Meditation alters brain connectivity in areas associated with emotion, MRI shows

Volunteers reported feeling less stressed after three months of Transcendental Meditation, and fMRI offered an important clue as to why, researchers reported in Brain and Cognition.

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.
