Ultrasound is an attractive imaging option due to the absence of ionizing radiation and low cost relative to other modalities. Because of this, researchers have been investigating ultrasound as a superior alternative for a number of indications, and this week’s top stories were dominated by these efforts.

A study of digital breast tomosynthesis (DBT) in clinical practice has once again shown a decrease in recall rates with the technology, but also revealed a significant difference in the distribution of the types of abnormalities recalled compared with digital mammography, according to results published online Sept. 22 in Radiology.

The Green Bay Packers football team purchased and installed a CARESTREAM digital X-ray system at Lambeau Field that can capture and display digital X-ray images of injured players in seconds. 

Using ultrasound (US) instead of CT as the initial imaging method for suspected nephrolithiasis can spare some patients from radiation while not significantly affecting outcomes according to a study published in the September issue of the New England Journal of Medicine

Patients undergoing CT imaging experienced anxiety over radiation exposure, claustrophobia and intravenous contrast, according to a study published online Sept. 16 in Academic Radiology.

MRI-guided breast biopsy yielded high-risk lesions in 21.5 percent of cases, according to a study published in the September issue of the American Journal of Roentgenology.

Model-based iterative reconstruction (MBIR) reduced radiation and noise levels in CT liver scans without diminishing image quality, according to a study published in the September issue of Radiology.

Researchers from the Singapore-MIT Alliance for Research and Technology have devised a way to diagnose malaria using magnetic resonance relaxometry, a similar technology to MRI.
