Editor's e-Note
CT is invaluable for lung imaging, and researchers are continually finding new ways to evaluate patients’ progress and response to therapy. This month, we’re highlighting a couple of studies with interesting findings.

Lung Damage May Persist Long After COVID-19 Pneumonia

The COVID-19 pandemic has considerably increased the demand for acute and postacute health care worldwide. COVID-19’s short-term effects on the lungs, such as pneumonia, are well documented, but much less is known about the illness’ long-term effects. According to a study published recently in Radiology, some people recovering from COVID-19 pneumonia have CT evidence of damage to their lungs that persists a full year after the onset of symptoms.

As part of an Austria-based observational study on the development of lung disease in patients with SARS-CoV-2 infection, researchers looked at patterns and rates of improvement of chest CT abnormalities in patients one year after COVID-19 pneumonia. CT has been an important imaging tool in the workup of patients suspected of having COVID-19.

The researchers assessed lung abnormalities on chest CT in 91 participants with a mean age of 59 years at several points over one year after the onset of COVID-19 symptoms. At one year, CT abnormalities were present in 49 (54%) of the 91 participants. Of these 49 participants, two (4%) had received outpatient treatment only, while 25 (51%) were treated on a general hospital ward and 22 (45%) had received ICU treatment.

“The observed chest CT abnormalities from our study are indicative of damaged lung tissue,” says study coauthor Anna Luger, MD, from the department of radiology at Innsbruck Medical University in Austria. “However, it is currently unclear if they represent persistent scarring and whether they regress over time or lead to pulmonary fibrosis.”

Space on the Brain
An MRI study on the effects of long duration spaceflight revealed notable changes in astronauts’ brains: Researchers noted increased cerebrospinal fluid buildup. What those changes indicate remains to be determined.

Learning to Do Without
A woman who grew up without the left temporal lobe of her brain, the region typically responsible for language development, hasn’t suffered any noticeable effects. Functional MRI is helping researchers understand why.

Sight and Sound
A technique that uses ultrasound to stimulate the retinas of vision-impaired people shows promise for restoring sight. Although currently only used in animal models, researchers hope to eventually apply it to humans, perhaps in the form of a contact lens.

Flights of Fancy
Functional MRI provides a window into the brain organization of creative people.
Worth Repeating
“With this new technology, it will allow us to see more than 2,000 patients a year, up from 1,218 patients in the past. IR offers patients a less painful procedure with less blood loss, lower risk of infection, and faster recovery time."
