Prehydration not needed before contrast CT of kidneys
February 18, 2020 -- Prehydrating patients who have chronic kidney disease before they undergo a contrast-enhanced CT exam has been the standard of care for years. But new research suggests that the practice results in unnecessary costs with few patient benefits. The findings were published online on February 17 in JAMA Internal Medicine.  Discuss

February 18, 2020 -- A mother in Colorado is considering suing after she discovered a CT image that showed a large screw embedded in the jaw of her 5-year-old daughter, which likely was left there during a surgery when she was an infant, according to news reports.  Discuss
CT lung screening risk models optimize nodule management
February 14, 2020 -- Risk prediction models can differentiate between benign and malignant nodules detected on CT lung cancer screening exams more accurately than current clinical guidelines, underscoring the potential value of the models for lung nodule management, according to a study published online February 14 in JAMA Network Open.  Discuss
Coronavirus toll surges after sanction of CT diagnosis
February 13, 2020 -- The number of new confirmed cases of coronavirus disease (COVID-19) in China hit roughly 15,000 within the past 24 hours alone, a major increase, according to news reports. The surge follows a decision by Chinese officials to expand the diagnostic criteria for COVID-19 to include cases diagnosed with CT.  Discuss
CT outpaces DNA testing for early coronavirus detection
February 13, 2020 -- Researchers from China are reporting that chest CT was able to detect COVID-19, the disease caused by the novel coronavirus (2019-nCoV), in individuals with high clinical suspicion of the virus -- even in cases with negative initial DNA tests -- in a study published online February 12 in Radiology.  Discuss
Mobile CT improves access to lung cancer screening
February 12, 2020 -- A mobile CT unit in North Carolina is bringing lung cancer screening directly to the communities of high-risk individuals faced with geographic and socioeconomic barriers to standard screening programs, improving their access to screening services, according to a study slated for publication in the March issue of the Oncologist.  Discuss
CT radiomics unlocks basal ganglia stroke onset time
February 11, 2020 -- The combination of radiomics and a machine-learning algorithm can determine on CT if an ischemic stroke in the basal ganglia occurred within the window of time in which a stroke patient can still receive thrombolysis, according to research published online February 10 in the Journal of the Neurological Sciences.  Discuss
3D micro-CT primed to revamp breast cancer imaging
February 11, 2020 -- Using 3D micro-CT to image breast cancer biopsy samples leads to a more precise assessment of cancer margins than the traditional histological approach and could improve the effectiveness of surgical treatment, according to a study published online February 4 in Breast Cancer Research and Treatment.  Discuss
Can 3D printing help optimize cardiac CT protocols?
February 7, 2020 -- Patient-specific 3D-printed coronary models have allowed clinicians to determine ideal cardiac CT protocols for various cardiovascular diseases with greater safety and accuracy than traditional testing methods, according to a review article published online on January 24 in Current Medical Imaging Reviews.  Discuss
CT traces disease progression in novel coronavirus
February 6, 2020 -- An ongoing investigation into the novel coronavirus (2019-nCoV) outbreak has characterized the most common CT findings associated with the virus and identified possible markers of disease progression several days after the onset of symptoms. The findings were published online February 6 in Radiology.  Discuss
