Low‐dose whole‐lung irradiation in severe COVID‐19 pneumonia: a controlled clinical trial

Introduction The COVID‐19 pandemic has caused significant morbidity and mortality thus far. Considering the historical uses of high‐voltage X‐ray beams for unresolvable pneumonia, we aimed to assess whether low‐dose whole‐lung irradiation (WLI) could provide any benefits for patients with refractory COVID‐19 pneumonia. Methods Eleven patients with refractory COVID‐19 pneumonia were treated with WLI to a total dose of 1 Gy and compared to 11...
