Radiologists have a key role to play in cancer staging, but many seem to need a nudge to get on with it. 

Volpara Solutions has won FDA 510(k) clearance for software designed to help radiologists meet the BI-RADS Atlas fifth-edition requirement to provide an overall assessment of the volume of attenuating tissues in the breast.

Determination of breast density fluctuates considerably from one exam to the next in any given woman. Such variability can both perplex the patient and drive unintended consequences into her care pathway.

In a retrospective comparison of 116 fetal MRI exams—half performed at 3T, half at 1.5T—the higher field strength produced the higher imaging scores. 

Gadolinium chelate administration is largely unnecessary for imaging pediatric tumors when performing MRI or combined PET/MR scans, according to a recent study published by the Journal of Nuclear Medicine.

A simulation study using two modeling approaches has shown that yearly digital breast cancer screening of U.S. women aged 40 to 74 may stave off 968 breast cancer deaths per 100,000 women screened—but the associated radiation exposure stands to cause 125 cancers leading to 16 deaths in the same cohort.

Scientists from Japan, Russia and the U.S. have discovered four new chemical elements that, taken together, complete the seventh period of the periodic table of elements. And the first area of human endeavor to find a practical use for the expanded knowledge may be nuclear medicine.

Subsequent breast cancers occur in patients with just their own premenstrual history of the disease at close to the same rate as in patients with both personal and family breast-cancer history, according to a study published online Jan. 7 in Academic Radiology.
