Breast cancer risk assessments should account for longitudinal changes in breast density, new data suggest

Breast density is known to drop over time, but the rate at which density decreases merits special attention, as it could be associated with a woman’s chance of developing cancer.

The Nanox.ARC imaging system

Nanox shares up 63% after scoring FDA clearance for new imaging system

The Nanox.ARC utilizes novel, cold-cathode X-ray tubes and charges physicians using a “pay per scan” business model.

Radioactive substances unnecessary in new method for measuring brain glucose metabolism

Rather than administering radiolabeled glucose for exams, imagers give patients a small amount of a harmless glucose solution that is said to be equivalent to a can of a carbonated drink.

X-ray photon trajectory during the simulation phantom study from the side and top views. Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.

Radiation exposure in the cath lab: Tracking the impact on interventional echocardiographers

Researchers found that echocardiographers in the cath lab are exposed to high doses of radiation on the right half of their body, especially the waist and lower body.
