Imaging reveals baby girl in SC born with 2nd mouth
June 23, 2020 -- Imaging, specifically MRI and CT, helped clinicians determine that a mass located on the chin of a newborn girl was a second oral cavity, according to a recent case report. The cavity contained unerupted teeth and an accessory tongue that moved in sync with her oral tongue.  Discuss
Chest CT clarifies negative COVID-19 lab results
June 19, 2020 -- The less pulmonary consolidation seen on chest CT, the more likely COVID-19 patients will have had initial negative reverse transcription polymerase chain reaction test findings, according to a study published June 18 in the American Journal of Roentgenology.  Discuss
AI algorithm detects appendicitis on CT exams in ER
June 18, 2020 -- South Korean researchers developed an artificial intelligence (AI) algorithm that was highly accurate and generalizable for detecting acute appendicitis on CT exams in emergency room (ER) patients. The algorithm could, if necessary, potentially fill in for a radiologist, according to research published online June 12 in Scientific Reports.  Discuss
COVID-19: Early signs of recovery, but uncertainty ahead
June 15, 2020 -- The global pandemic has created an unprecedented shock to the medical imaging and healthcare sectors. What is the future likely to hold? What are the key economic trends, bright spots, and areas of greatest risk? Market columnist Steve Holloway investigates.  Discuss
RSNA's COVID-19 chest CT classification system holds up
June 12, 2020 -- A chest CT classification system developed by the RSNA for interpreting COVID-19 pneumonia cases shows substantial agreement among readers, according to a study published June 11 in Radiology: Cardiothoracic Imaging.  Discuss
Use D-dimer, CTPA to gauge PE risk in COVID-19 patients
June 12, 2020 -- Patients with COVID-19 who have high D-dimer levels are good candidates for CT pulmonary angiography (CTPA) to rule out acute pulmonary embolism (PE), according to a study published June 9 in European Radiology.  Discuss
Muscle metrics on chest CT can predict mortality risk
June 12, 2020 -- Measurements of muscle mass and density automatically extracted from chest CT exams using an artificial intelligence (AI)-based model can predict all-cause mortality over a six-year period in older men, according to research published online June 6 in the Journals of Gerontology.  Discuss
PET/CT confirms breast cancer predicted by blood markers
June 11, 2020 -- FDG-PET/CT can detect breast cancer metastases predicted by elevated tumor marker values in asymptomatic patients who have already undergone locoregional treatment, according to a study published June 9 in Oncology.  Discuss
CT illuminates why nonsmokers get COPD
June 9, 2020 -- A study using CT to image the lungs of patients has found that people with small airways relative to their lung size may be at increased risk of chronic obstructive pulmonary disease (COPD), even if they don't have other risk factors, such as smoking or asthma. The research was published June 9 in JAMA.  Discuss
Deep learning refines cardiac CT results
June 5, 2020 -- A deep-learning algorithm refines cardiac CT results by automatically eliminating exams negative for coronary artery calcium -- streamlining radiology workflow, according to a study published June 3 in the European Journal of Radiology.  Discuss
