An accidental discovery could have future implications for the material makeup for MRI contrast media.

The new technique uncovers hidden inflammation in patients who, despite undergoing extensive treatment for the condition, had worsening symptoms.

Finding such discrepancies is critical to the continuity of patient care, as medical records and reports are often utilized across multiple providers and facilities.

Johns Hopkins researchers demonstrated the worthiness of the concept this year.

This could be especially helpful when timely clinical decisions relative to the use of a contrast agent need to be made.

With the earth’s warmest March on record in 175 years barely in the rearview mirror, a team of radiology experts says medical imaging must step up its sustainability efforts. 

Advanced artificial intelligence (AI) models can evaluate cardiovascular risk in routine chest CT scans without contrast, according to new research published in Nature Communications.[1] In fact, the authors noted, the AI approach may be more effective at identifying issues than relying on guidance from radiologists. Representative non-contrast CT slices for two patients (left), with super-imposed segmentations (right). One artificial intelligence (AI) model was used to segment a cardiac mask.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans.

Advanced imaging equipment using ionizing radiation enters the global market at the rate of one new technology every five years.

Example of the four types of breast tissue density. The density of fibroglandular tissue inside the breast impacts the ability to easily see cancers. Cancers are very easy to spot in fatty breasts, but are almost impossible to find in extremely dense breasts. These examples show craniocaudal mammogram findings characterized as almost entirely fatty (far left), scattered areas of fibroglandular density (second from left), heterogeneously dense (second from right), and extremely dense (far right).

Dense breast experts Wendie Berg, MD, and JoAnn Pushkin, executive director of DenseBreast-info Inc., explain the current status of breast density patient inform laws, reimbursement and new technologies to aid cancer detection. 

Compared to USPSTF 2013,  modified eligibility criteria could increase cancer detection by 37%.

Illustration of the four types of breast tissue densities. The more dense, the harder it is for radiologists to detect cancers, which had led to about 40 states to now require notiofication of patients if they have dense breasts and the impact on their care, with possible miss-reads and that they may need supplemental imaging.

Society of Breast Imaging (SBI) President John Lewin, MD, discusses how legislation concerning breast density notifications has impacted mammography.

Recently a radiomics-based machine learning model proved highly accurate at predicting which patients would develop pancreatic cancer three to 36 months after abdominal CT imaging.
