Published June 22, 2020 To date, the radiology literature on coronavirus disease (COVID-19) pneumonia has consisted of limited retrospective studies that do not substantiate the use of CT as a diagnostic test for COVID-19. “This is not to say these studies are not valuable,” maintained lead investigator Constantine A. Raptis of Washington University in Saint […]
Low Back Pain Accounts for a Third of New Emergency Imaging in the U.S.
The use of imaging for the initial evaluation of patients with low back pain in the emergency department (ED) continues to occur at a high rate—one in three new emergency visits for low back pain in the United States. “Although there has been a modest decline,” wrote Jina Pakpoor of the University of Pennsylvania, “in […]
Deep Learning Differentiates Small Renal Masses on Multiphase CT
A deep learning method with a convolutional neural network (CNN) can support the evaluation of small solid renal masses in dynamic CT images with acceptable diagnostic performance. Between 2012 and 2016, researchers at Japan’s Okayama University studied 1,807 image sets from 168 pathologically diagnosed small (≤ 4 cm) solid renal masses with four CT phases—unenhanced, […]
A Step Toward Automated Triage of Thyroid Cancer
A Stanford University team has developed a quantitative framework able to sonographically differentiate between benign and malignant thyroid nodules at a level comparable to that of expert radiologists, which may prove useful for establishing a fully automated system of thyroid nodule triage. Alfiia Galimzianova et al. retrospectively collected ultrasound images of 92 biopsy-confirmed nodules, which […]
