Quality improvement effort slashes CT radiation dose
A simple and cost-effective intervention led to reductions in CT radiation dose as high as 58% -- without a notable drop in image quality -- for a cohort of nearly 1 million individuals from 100 facilities across the globe in a new study. The findings were published online March 30 in JAMA Internal Medicine.

AR, 3D printing set to improve cranial surgery outcomes
Researchers from Brazil have developed a way to visualize and interact with patient-specific anatomy using augmented reality (AR) and 3D printing. They describe how the technique could improve preoperative planning for cranial surgery and patient outcomes in an article in the March issue of Neurosurgical Focus.

RSNA proposes standardized CT reporting for COVID-19
CT is currently not recommended as a first-line diagnostic or screening tool for COVID-19, but its use to understand and manage the disease continues to grow. In response, the RSNA proposed standardized CT reporting language for COVID-19 in a special report posted on March 25 in Radiology: Cardiothoracic Imaging.

Imaging confirms coronavirus transmits from mother to fetus
The combination of CT, x-ray, and DNA testing confirmed that the novel coronavirus was transmitted from pregnant women to nearly 10% of newborns in a new study, published online March 26 in JAMA Pediatrics. The findings underscore the need for strict infection control measures for this vulnerable population.

CT shows parallels between vaping lung injury, COVID-19
COVID-19 and vaping-related lung injury share many features on CT, but the imaging modality's role in diagnosing the diseases has taken diverging paths, according to a March webinar hosted by the American Roentgen Ray Society.

CT depicts how COVID-19 abnormalities change over time
CT scans revealed rapid progression of abnormalities in COVID-19 patients, typically peaking on the 10th day from symptom onset, in a new study published March 19 in Radiology. The persistence of CT abnormalities through the final stages of disease underscores the need to monitor patients well after discharge.

CT details effect of COVID-19 on pregnant women
Does COVID-19 have a more devastating effect on pregnant women? Is the disease passed down to newborns after birth? What's the best management strategy for this vulnerable population? Researchers from China addressed these and similar questions in a March 18 study published in the American Journal of Roentgenology.

Women have more chest pain despite less stenosis on CCTA
Women with coronary artery disease are much more likely to have frequent chest pain than men, despite having less extensive disease on coronary CT angiography (CCTA) and less severe ischemia on stress imaging, according to a study.

ACR recommends sparing use of CT for COVID-19
CT should not be used as a first-line diagnostic or screening tool for the novel coronavirus disease (COVID-19), according to a March 11 statement by the American College of Radiology (ACR). The statement covers the appropriate use of chest x-ray and CT for the screening, diagnosis, and management of COVID-19.

There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis.

(C) Axial proton density-weighted fat-suppressed, (D) sagittal T2-weighted fat-suppressed, and (E) sagittal T1-weighted MRI scans show continuation into a nondisplaced anteroinferior labral tear (arrows).
