Arru CD, Digumarthy S, Hansen JV, et al. - In this retrospective institutional review board-approved study, patients with COVID-19 pneumonia with and without pulmonary embolism (PE) were assessed for the differences in qualitative and quantitative parameters of pulmonary perfusion from dual-energy computed tomography (CT) pulmonary angiography (DECT-PA). Included were 74 patients (mean age 61 ± 18 years, male:female 34:40) with COVID-19 pneumonia who underwent DECT-PA on either dual-source (DS) or single-source (SS) multidetector CT machines. Pulmonary emboli was detected on DECT-PA in one-fifth of patients with COVID-19 pneumonia. Relative to subjective CT score, perfusion statistics were identified as superior in identifying PE patients and in finding patients with low SpO2. Cases of COVID-19 pneumonia did not exhibit distinctive features with respect to pulmonary perfusion.
