Abstract
In memory of the founder of Acta Radiologica, Professor Gösta Forsell, the Xenia Forsselliana Prize has been awarded for the best manuscript from one of the five Nordic countries published in the print version in Acta Radiologica that specific year.
After a formal voting procedure, the section editors of Acta Radiologica have decided that the Xenia Forsselliana Prize for 2022 should be awarded to Dr Maria Tækker from the Department of Radiology, Odense University Hospital, Odense, Denmark (Fig. 1) for the article “Diagnostic accuracy of ultra-low-dose chest computed tomography in an emergency department” (1).
Dr Maria Tækker.
Dr Maria Tækker was born in 1995 and got her MD in 2021 at the University of Southern Denmark, Odense. She is currently employed as a foundation doctor in the Department of Gynecology and Obstetrics at the Hospital of Southern Jutland.
In 2019–2020, Dr Tækker conducted research as an extension of her master's degree. During that year, Dr Tækker worked on three articles with her team, one of which was the prize-winning paper. The project was a joint venture between the Research Unit of Radiology and Emergency Department of Odense University Hospital, Denmark.
The aim of the paper was to examine whether ultra-low-dose chest computed tomography (ULD-CT) could improve the detection of acute chest conditions. ULD-CT (0.05 mSv) was compared to a supine chest X-ray (sCXR) (0.01 mSv) for acute chest conditions, and the feasibility of ULD-CT in an emergency department was explored. The 91 patients enrolled in the study received a ULD-CT, sCXR, and non-contrast chest CT (NCCT) scan, and radiologists assessed the examinations for acute chest conditions. The diagnostic accuracy of ULD-CT and sCXR was calculated using NCCT as the gold standard, and resources and effort were compared for the two modalities. The median examination time was twice as high for ULD-CT compared to sCXR (10 vs. 5 min) and 1–2 more staff members were needed to perform a ULD-CT. For the diagnosis of pneumonia and pneumothorax, the ULD-CT showed improved sensitivity compared to sCXR. There was no difference in diagnostic accuracy between the two modalities for cardiogenic pulmonary edema and pleural effusion. In conclusion, ULD-CT seems equal or better in the detection of acute chest conditions; however, the examination demands more effort and resources.
Dr Maria Tækker has published two articles as a main author and one article as a co-author.
The Prize consists of SEK 40,000 and a diploma. The official presentation of the Prize will take place during the Nordic Congress of Radiology in Helsinki at the Acta Radiologica Award Session in May 2023. The manuscript will be presented orally during the Acta Radiologica Award Session.
The Editorial Board congratulates Dr Maria Tækker for winning the 2022 Xenia Forsselliana Prize.
