Xenia Forsselliana 2010.

TLDR: The Xenia Forsselliana Prize of SEK20,000 and a Diploma, has been awarded to Dr Gunnar Moen, Haukeland University Hospital, Bergen, Norway, for his article ‘Cerebral diffusion and perfusion deficits in North Sea divers’ (1).

Abstract: The Xenia Forsselliana Fund was established in 1941, based on a sum of money given in occasion of the celebration of the 65th birthday of Gösta Forssell. The aim of the fund was to promote radiological research. In 1992, it was decided that a prize from this fund should be awarded annually for the best article from one of the Nordic radiological institutions published in Acta Radiologica. The prize was awarded for the first time in 1992, and the first recipient was Mats Wikström from Uppsala, Sweden. Since then, the following recipients have been awarded the prize: Wojciech Cwikiel, Lund, Sweden (1993); Tapani Tikkakoski, Kokkola, Finland (1994); Reidar Dullerud, Oslo, Norway (1995); Peter Leander, Malmö, Sweden (1996); Beata Boné, Stockholm, Sweden (1997); Marika Cronhjort, Stockholm, Sweden (1998); Per Skaane, Oslo, Norway (1999); Marja Perhomaa, Oulu, Finland (2000); Heidi B Eggesbø, Oslo, Norway (2001); Montserrat Alemany Ripoll, Uppsala, Sweden (2002); KatriinaBöckerPuhakka, Aarhus, Denmark (2003); Jenny Vikgren, Gothenburg, Sweden (2004); Per Skaane, Oslo, Norway (2005); Hampus Eklöf, Uppsala, Sweden (2006); Barbara Elmståhl, Malmö, Sweden (2007); Nils Albiin, Stockholm, Sweden (2008); and Jonaz Ripsweden, Stockholm, Sweden in 2009. The editorial board of the journal appoints the prize winner based on voting of what the editorial board considers as the best scientific presentation. The Xenia Forsselliana Prize of SEK20,000 and a Diploma, has, for 2010, been awarded to Dr Gunnar Moen (Fig. 1), Haukeland University Hospital, Bergen, Norway, for his article ‘Cerebral diffusion and perfusion deficits in North Sea divers’ (1). Dr Moen graduated from The University of Bergen, Norway and obtained his MD in 1983. He has a broad education within radiology and has served in different positions at several university hospitals in Norway. He is a recognized specialist in Neuroradiology and Interventional Neuroradiology with subspecialized education from Oslo University Hospital, Norway, The Radcliffe Infirmary, University of Oxford, UK, and The University Hospital in Lund, Sweden. He is the author/co-author of close to 30 peer-reviewed scientific publications. The background of the study was that diving, especially deep sea diving, is associated with a risk of cerebral decompression illness, and the prevalence of neurological symptoms is higher in divers compared with control groups. This has become obvious in a large group of divers from the first period of the oil industry in the North Sea where deep sea divers played an important role. The purpose of the study was to investigate if possible functional derangements of the microvasculature and microstructure would be more prevalent among symptomatic divers. Magnetic resonance imaging (MRI) was performed in 91 former divers and 45 controls. Individual parametric images of apparent diffusion coefficient (ADC), cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) were generated on the basis of diffusionand perfusion-weighted imaging. Significant regional group differences were found in all four parametric comparisons. Gross regional ADC differences were seen throughout the brain, including large frontal and temporal white-matter regions, the hippocampus, and parts of the cerebellum. The findings may explain some of the long-term clinical symptoms reported among professional divers. The official presentation of this award will take place place during the 59th Nordic Congress of Radiology at Åland in June 2011.
