Deep learning detects precancerous changes on mammograms

What’s more, the model proved beneficial in a large, diverse cohort that included women with benign breast disease and BRCA mutations.

Evidence supporting use of radiomics is 'insufficient' and 'weak,' according to new meta-analysis

Although the predictive power of radiomics has been touted as a tool that could improve patient outcomes, the method has a long way to go before it can be reliably introduced into real-world clinical environments.

PROMISE trial results reinforce confidence in new MRI contrast agent

The randomized, double-blinded phase 3 study revealed gadopiclenol to be noninferior to gadobutrol for all qualitative visualization parameters as rated by all blinded readers involved in the trial.

NIST researchers improve portable MRI

Improving low-field MRI scanners with quantitative data

Researchers at the National Institute of Standards and Technology (NIST) are working on developing measurements that will provide better insight into soft tissue properties visualized on portable MRI images.

ImpressionGPT, a ChatGPT-based framework, can accurately summarize radiology reports

The program leverages the in-context learning abilities of large language models to generate report summaries using domain-specific, individualized data relative to radiology.

New discovery paves the way for copper's entrance into MRI contrast agents

The new discovery contradicts the notion that copper is not suitable for use in contrast media.

A figure from the study shows a chest radiograph with an area of consolidation involving right lower lung consistent with pneumonia, as well as right pleural effusion. The deep-learning model predicted risk of 30-day mortality of 9%. Right: Gradient- weighted class activation map shows that model prediction was influenced by separate area of image corresponding with heart and liver (yellow and light blue colors). Patient’s CURB-65 score was 4. Patient recovered from pneumonia and remained alive. AJR Image

Deep learning predicts pneumonia mortality on chest X-rays

AI was able to predict 30-day mortality risk predictions more accurately that the current risk assessment.

Cardiac ultrasound could lead to key advances in heart attack care, drug delivery

Jonathan Lindner, MD, offers an update on the use of echocardiography and bubble contrast agents in a therapy role to help revascularize STEMI patients and increase drug and gene delivery.

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.
