Imaging patterns predict gunshot injury readmission rates
November 27, 2019 -- Imaging findings from diagnostic imaging exams could help determine which patients with gunshot injuries are most likely to have future health complications and end up returning to the hospital for additional medical treatment, according to a study to be presented at RSNA 2019 in Chicago.  Discuss
Micro-CT unveils curious history of ancient manikins
November 27, 2019 -- Long before the advent of modern-day imaging modalities, clinicians used manikins to study medical anatomy. Researchers from Duke University will share how they used micro-CT to uncover the internal features and material composition of these human figurines in a presentation at the RSNA 2019 meeting in Chicago.  Discuss
Naval dental school failed to read 1,800 CBCT scans
November 27, 2019 -- Radiologists at Walter Reed National Military Medical Center's Naval Postgraduate Dental School in Bethesda, MD, failed to examine about 2,000 dental conebeam CT (CBCT) scans during a seven-year period, resulting in at least one treatment delay, according to news reports.  Discuss
CT radiomics predicts lung cancer immunotherapy response
November 26, 2019 -- A new radiomics technique can determine which lung cancer patients will benefit from immunotherapy by analyzing the texture, volume, and shape of lesions on chest CT scans, according to a study published online November 12 in Cancer Immunology Research.  Discuss
CT usage rates escalate for eye-related emergencies
November 25, 2019 -- The utilization rate of emergency CT for eye-related injuries has more than doubled over the past decade, according to a study recently published online in the American Journal of Ophthalmology. The trend underscores the need to establish more effective criteria for emergency eye imaging, researchers say.  Discuss
Vaping case in Canada unearths new lung injury on CT
November 22, 2019 -- As the vaping epidemic continues to unfold, a new case study centered on a previously healthy 17-year-old male has revealed yet another clinical indication of vaping-associated lung injury evident on CT scans. The case was published online November 21 in the Canadian Medical Association Journal.  Discuss
CT radiation increases risk of thyroid cancer, leukemia
November 20, 2019 -- Researchers from the U.S. and Taiwan have identified an association between radiation exposure from CT scans and an increased risk of thyroid cancer and leukemia in a large-scale, population-based study. The findings are covered in an article published online on November 19 in JNCI Cancer Spectrum.  Discuss
CCTA, functional tests stratify heart disease risk by age
November 18, 2019 -- The combination of coronary CT angiography (CCTA) scans and functional tests such as stress echocardiography can predict the likelihood of heart attack and death in individuals at risk of coronary artery disease (CAD) based on their age, according to a study published online November 18 in JAMA Cardiology.  Discuss
Medical radiation dose dips 20% in U.S., NCRP reports
November 18, 2019 -- Is medical imaging making headway in its efforts to reduce patient exposure to medical radiation? In an update to its report on radiation exposure, the U.S. National Council on Radiation Protection and Measurements (NCRP) found that the average medical radiation dose has decreased by 15% to 20% over the past decade.  Discuss
