Commercially available AI tool could reduce radiologist workloads by 10% or more

The tool’s sensitivity was recorded as 99.1% for abnormal radiographs and 99.8% for critical radiographs—better than two board-certified radiologists who also interpreted the exams. 

How do hormonal contraceptives affect breast density?

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).

Example of the four types of breast tissue density. The density of fibroglandular tissue inside the breast impacts the ability to easily see cancers. On X-ray mammography, cancer and dense breast tissue both appear as white and can hide smaller cancers on 2D mammography. Dense breasts are also a risk factor for cancer. 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).

How recent developments in hormonal contraceptives affect breast density is an important consideration, as an increase in density category increases cancer risk.

Experts develop cardiac MRI reference values for healthy adolescents

The newly developed reference values could have “direct implications for clinical practice” and can be used by any provider to determine whether an adolescent falls within the normal range of measurements for their age group.
