MRI shows routine football hits damage the brain
August 8, 2019 -- Brain MRIs have shown that it's not just concussions that damage the brains of football players but also routine hits over the course of a season, according to a study published online August 7 in Science Advances. Read More
AI may help cut back on overutilization of CT for PE
August 8, 2019 -- An artificial intelligence (AI) algorithm can predict -- from electronic medical record data -- if a patient is likely to have a pulmonary embolism (PE) prior to receiving CT pulmonary angiography, potentially avoiding unnecessary scans, according to research published online August 7 in JAMA Network Open.

Biennial follow-up exams prove safe for CT lung screening
August 8, 2019 -- Biennial CT lung cancer screening is a safe alternative to annual screening, say researchers from Italy. They found that both approaches led to similar reductions in cancer and all-cause mortality in a new analysis of the Multicentric Italian Lung Detection trial published in the September issue of the European Journal of Cancer.

3D-printed head customizes neurosurgery simulation
August 8, 2019 -- Researchers from Australia have created a 3D-printed head model, based on a combination of MRI and CT angiography scans, that allows for the realistic simulation of neurosurgical procedures. They discuss the specifics of their method in an article published online August 1 in 3D Printing in Medicine. Read More
AI shows promise for reducing mammography workload
August 7, 2019 -- An artificial intelligence (AI) algorithm can improve the specificity of mammography interpretation without affecting sensitivity and reduce the mammography workload for radiologists by nearly one-fifth, according to a new study published online August 6 in Radiology. Read More
AI-based model enhances diagnosis of brain MRI exams
August 7, 2019 -- An artificial intelligence (AI)-based model that mimics a radiologist's image interpretation process can provide automated diagnosis of brain MRI exams at a level comparable to an academic neuroradiologist, according to researchers from the Hospital of the University of Pennsylvania in Philadelphia.

PSMA-PET/CT most effective for recurrent prostate cancer
August 7, 2019 -- PET/CT is significantly better at detecting prostate cancer recurrence when used with the radiopharmaceutical gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) than with F-18 fluciclovine, according to an article recently published online in Lancet Oncology. Read More
Radiology business intelligence grows in demand
August 7, 2019 -- Commercial activity surrounding radiology business intelligence software has picked up recently with a new generation of applications entering the market. Why are imaging IT vendors focusing on adding these tools to their portfolios? Ulrik Kristensen, PhD, from Signify Research reviews the key forces driving growth. Read More
USPSTF again dismisses pancreatic cancer screening
August 6, 2019 -- The U.S. Preventive Services Task Force (USPSTF) has reaffirmed its prior decision to recommend against imaging-based screening for pancreatic cancer in asymptomatic individuals, in a recommendation statement published online August 6 in the Journal of the American Medical Association.
