Chest CT effective for COVID-19 diagnosis

By Kate Madden Yee

French researchers have found that chest CT is an effective tool for initial diagnosis of COVID-19, according to a study published September 1 in Radiology. The results challenge current guidelines that have discouraged initial use of CT for COVID-19.

Virtual imaging trials could optimize COVID-19 imaging

By Erik L. Ridley

Researchers have created computerized models of lung abnormalities on CT scans of patients with COVID-19, according to an August 28 study in the American Journal of Roentgenology. The virtual imaging models can be used like computerized phantoms for research into the use of imaging to detect and monitor the disease.

AI algorithm may be generalizable for spotting COVID-19

By Erik L. Ridley

An artificial intelligence (AI) algorithm trained on a large, multinational dataset can be highly accurate for identifying COVID-19 pneumonia on chest CT scans, according to research published online August 14 in Nature Communications. It can also be highly specific for non-COVID-19-related pneumonias.

Transcranial ultrasound helps solve COVID-19 mystery

By Theresa Pablos

Ultrasound scans with a robotic transcranial Doppler device provided a clue into why patients with COVID-19 experience severe hypoxemia without lung stiffness. In a serendipitous discovery, researchers linked the ultrasound findings to suspiciously low oxygen levels in patients with severe cases of COVID-19.

3D CT models can help assess COVID-19 lung damage

By Erik L. Ridley

Can advanced visualization techniques used to research the lungs of reptiles and birds also help diagnose COVID-19 in humans? Applying methods from evolutionary anatomy research, a Louisiana State University team has created 3D digitally segmented models that demonstrate the extent and distribution of the disease.

MRI is a good alternative to CT for COVID-19 diagnosis

By Erik L. Ridley

Chest CT has been widely used to diagnose COVID-19 disease, but MRI offers an attractive alternative that doesn't require radiation, according to a study published August 15 in Academic Radiology.
