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.

Carotid lumen size linked to death from all causes
By Theresa Pablos
Carotid lumen diameter derived from ultrasound scans was linked to a higher risk of death from all causes in a recent study in the Journal of the American Heart Association. Larger lumen size also proved to better predict cardiovascular mortality than carotid intima-media thickness measurement.
