AI can spot smokers at high risk of cancer on x-rays
By Erik L. Ridley
By analyzing chest radiographs and a patient's electronic medical record (EMR), a deep-learning algorithm was able to identify more high-risk smokers who could benefit from CT lung cancer screening than current Medicare eligibility criteria, according to research published September 1 in the Annals of Internal Medicine.

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.
