Whole-body MRI (WB-MRI) staged colorectal and lung cancer patients with accuracy similar to standard staging pathways, but WB-MRI saved valuable time and costs associated with screening, according to results of two new trials published May 9.

The tool, ultralow radiation imaging coupled with image enhancement and instrument tracking (ULR-IE/IT), reduced the total time to localize an instrument by more than 30% and cut radiation exposure by more than 90% compared to C-arm fluoroscopy.

Tau levels found in concussed former athletes may help predict who will ultimately suffer from long-term effects of blows to the brain, according to a new study published in Neurology.

“To our knowledge, no study has examined how changes in categorization of calcification from the 4th to the 5th edition of BI-RADS have affected positive predictive values (PPVs)," wrote authors of a recent study published in the American Journal of Roentgenology.

Four-dimensional (4D) CT can reliably evaluate ligament injuries in the ankle and may be used to test the ankle in-motion to spot asymptomatic problems, according to results of a May 8 study published in Clinical Radiology.

The U.S. Nuclear Regulatory Commission (NRC) opened a 30-day public comment period seeking feedback on its draft document outlining training and experience requirements for administrating radiopharmaceuticals requiring a written directive.

Researchers found an “abrupt and substantial” decline in the national radiologist workforce 30 years after residency, according to a new study published in Academic Radiology. They also investigated the post-residency practice patterns of readers.

The researchers analyzed the frequency and cancer yield of ACR Breast Imaging Reporting and Data System (BI-RADS) 3 lesions in patients who received baseline and non-baseline screening MRIs.

"It remains poorly understood how much radiologists vary when recommending additional imaging and what additional radiologists and other factors influence the likelihood of additional imaging," wrote authors of a new study published in Radiology.

The FDA has issued two final guidance documents regarding x-ray devices designed to more closely align FDA requirements with internationally developed standards.

The deep learning (DL) model was also equally as accurate for racial minorities who have proven to be more likely to die from cancer, such as black women, according to a May 7 study published in Radiology.

 

A CT angiography (CTA) approach with "drastically" lowered tube currents combined with iterative construction reduced radiation exposure and maintained image quality in patients with suspected acute stroke, reported authors of a recent study published in the American Journal of Roentgenology.
