[Christmas article: The best bubbles - radiology as sommelier].

Introduction: The aim of the study was to assess bubble characteristics in three different sparkling wines, two different sparkling waters, one standard beer and one demineralised water for ironing with CT, MRI and ultrasound (US). Furthermore, the correlation between personal taste and the measured bubble intensity should be assessed.

Methods: The study was carried out as a prospective study.

[Christmas article. MRI assessment of the optimal type of traditional pork roast and preparation method - a randomised blinded trial].

Introduction: Pork roast is part of the traditional Danish Christmas meal and has been so for several hundreds of years. A novel cooking method is sous vide, in which the meat under vacuum is cooked for a long time at low temperature. Can MRI predict the optimal type of traditional pork roast and the optimal preparation method: oven or sous vide preparation?

Methods: Two different pork roasts, one from an ordinary pig and one from a pig from an organic farm, were divided in two and randomised to oven cooking or sous vide.
