Emerging research shows a 14.5 percent increase among African Americans getting screened for lung cancer, which may be attributable to the United States Preventive Services Taskforce (USPSTF) lowering the minimum screening age to 50 and decreasing the smoking intensity screening threshold from 30 pack years to 20 pack years in March 2021.
In what may be the largest study to date to examine the use of whole-body imaging to assess multisystem thrombosis in patients with COVID-19 vaccine-induced immune thrombotic thrombocytopenia, researchers found multiple sites of thrombosis in 83 percent of patients who had additional CT, MRI and/or ultrasound imaging beyond the area of their primary complaint.

In a newly published statement, the American College of Radiology cited questionable literature support for the recent FDA guidance and noted potential consequences ranging from diagnosis delays due to parental anxiety about contrast-enhanced computed tomography (CECT) and increased health care costs.
A new survey study from the American Cancer Society shows a 4.47 million decrease in cervical cancer screenings and a 2.13 million decrease in breast cancer screenings in the United States between 2018 and 2020.
In a recent video interview on the current iodinated contrast media shortage, neuroradiologist Sean Bryant, MD discussed imaging alternatives, emphasized communication with referring physicians on optimal studies, and discussed the ongoing need to prevent “protocol creep” with timely updates of imaging protocols.
The resumed production of GE Healthcare’s Omnipaque products is a welcome development for radiologists scrambling to come up with alternative dosing and imaging options in the past month during the temporary shortage of iodinated contrast media.

For post-op monitoring of patients who had pancreatic ductal adenocarcinoma (PDAC) resection, a new study showed that diffusion-weighted magnetic resonance imaging (MRI) had enhanced sensitivity for detecting recurrent tumors in comparison to conventional MRI.
Deep radiomics models that included deep learning features had a 40 percent or greater increase in the specificity rate for diagnosing osteoporosis on hip radiographs in comparison to models that only emphasized clinical and/or textural features.
The new artificial intelligence-powered software reportedly helps detect central pulmonary embolism (PE) on computed tomography pulmonary angiogram (CTPA) images and streamlines communication among interventional teams to bolster treatment outcomes.
In a study of over 11,500 patients who had BI-RADS 4 breast lesions with no prior history of breast cancer, researchers found no statistically significant differences between digital mammography and digital breast tomosynthesis in cancer detection rates or biopsy-derived positive predictive value.
A new study revealed that an emerging artificial intelligence (AI)-enabled software tool led to improved sensitivity, specificity and inter-observer agreement for the diagnosis of indeterminate pulmonary nodules on chest computed tomography (CT) scans.
