This contribution accompanies the Roentgen Lecture the author gave on November 13, 2020 in Roentgen’s birth house as part of its inauguration and the closing ceremony of the 101st Congress of the German Roentgen Society in Remscheid-Lennep. KEY POINTS · The development of computed tomography was a milestone in the methodological advancement of imaging with X-rays.. · In the detector pixel invisible X-rays are converted into digital electrical impulses, which the computer uses to create images.. · Photon-counting detectors could have significant diagnostic advantages for clinical applications.. CITATION FORMAT · Schlemmer H, The Eye of the CT Scanner The story of learning to see the invisible or from the fluorescent screen to the photon-counting detector.

As a cross-section discipline within the hospital infrastructure, radiological departments might be able to provide important information regarding the impact of the COVID-19 pandemic on healthcare. The goal of this study was to quantify changes in medical care during the first wave of the pandemic using radiological examinations as a comprehensive surrogate marker and to determine potential future workload.
A retrospective analysis of all radiological examinations during the first wave of the pandemic was performed. The number of examinations was compared to time-matched control periods. Furthermore, an in-depth analysis of radiological examinations attributed to various medical specialties was conducted and postponed examinations were extrapolated to calculate additional workload in the near future.
A total of 596,760 examinations were analyzed. Overall case volumes decreased by an average of 41 % during the shutdown compared to the control period. The most affected radiological modalities were sonöntgenstr 2021; DOI 10.1055/a-1368-5047.

After continuous evolution, the revised Atlanta classification was published in 2012. In this updated classification, imaging aspects were better integrated and unclear terms were better defined. To date, this terminology for disease grading, severity, and local complications has been solely available in English. This prevented wide acceptance of the classification by the German-speaking medical community. Therefore, an expert team of the German Radiological Society translated the terms based on German medical literature. This translation was approved by consensus in the new S3 guideline meeting in February 2020 with an approval rate of 97.3 %. This manuscript explains the translated and approved German terminology of the revised Atlanta classification and offers additional imaging examples. KEY POINTS · The revised Atlanta classification allows correct definition of the grading and complication assessment of acute pancreatitis.. · An expert group translated the terms into the German language. The translation was approved by the S3 guideline committee for pancreatitis.. · Based on the new German S3 guideline for pancreatitis, the translated terms should be employed consistently..

The technically caused delay between low-energy (LE) and high-energy (HE) acquisitions allows motion artifacts in contrast-enhanced dual-energy mammography (CEDEM). In this study the effect of motion correction by nonrigid registration on image quality of the recombined images was investigated.
Retrospectively for 354 recombined CEDEM images an additional recombined image was processed from the raw data of LE and HE images using the motion correction algorithm. Five radiologists with many years of experience in breast cancer diagnostic imaging compared side-by-side one conventional processed CEDEM image with the corresponding image processed by the motion correction algorithm. Every pair of images was compared based on six criteria General image quality (1), sharpness of skin contour (2), reduction of image artifacts (3), sharpness of lesion contour (4), contrast of lesion (5), visibility of lymph nodes (6). These criteria were rated on a Likert scale (improvement + 1, + 2; deterioration -1, -2).
The mean ratings concerning criteria 1-5 showed a superiority of the recombined images processed by the motion correction algorithm.
