Annual opening celebration
For us, not only working and researching together is great fun, but also cooking together! So we created a 4-course menu for our working groups at the annual opening ceremony and had a successful and tasty start into the new year. Thanks to Prof. Dewey for the great location idea. 2020 here we come!
Social Cohesion and Medical Imaging Meeting
The kick off meeting for the work on Social Cohesion and Medical Imaging within the “Berlin University Alliance”, in which Prof. Dewey is the main applicant, took place on 8. & 9. of January in the “Window of Science” in the CCO at the Charité Campus Mitte. We are looking forward to the results of this promising cooperative project.
Group Dewey on perspective meeting/Teambuilding
In order to start strong into the new year, the group of Prof. Dewey conducted a perspective meeting including a fun and mind opening teambuilding event. Not only the whole groups mental skills were asked, but also the physical ones (as you can see in the picture) from time to time at this whole day event. We thank for the invitation and the great idea and look forward to take on every challenge of the new year!

He is tweeting about #medical #imaging #radiology and everything related and looking forward for an exchange via Twitter with you.
Results on clinical trials in radiology and data sharing
In this work of Dr. , Prof. Bernd Hamm and Prof. Marc Dewey randomised trials were analysed, since they are a key contributor to evidence-based medicine and radiology. They play an increasingly important role in developing evidence-based strategies for diagnostic management and image-guided treatments.
Scientific discoveries will increasingly depend on sharing data on a global scale. While data sharing is rather common in life sciences, data sharing is lagging behind in clinical medicine including medical imaging. Medical imaging and radiology play a central role in patient care and typically create very large data sets, which are challenging to curate, share, and reanalyse . Thus, we conducted an online survey among European heads of imaging departments and speakers at the Clinical Trials in Radiology sessions at the European Congress of Radiology (ECR) 2015-2018 to ascertain the current situation and anticipate future directions of imaging trials and data sharing in radiology.

The Bionic Radiologist: avoiding blurry pictures and providing greater insights.
Prof. Dr. Marc Deweys and Uta Wilkens latest realease helps at a practical level to achieve the following critical goals: (1) testing decisions being made scientifically on the basis of disease probabilities and patient preferences; (2) image analysis done consistently at any time and at any site; and (3) treatment suggestions that are closely linked to imaging results and are seamlessly integrated with other information.
The Bionic Radiologists promises better outcomes and lower costs through better integration of diagnostic imaging in clinical care processes. In this perspective we outlined the characteristics and facilitating factors with respect to the technology development itself, the surrounding institutional conditions and resistance due to the required change in culture as well as the prerequisites for individual acceptance and adaptation.
The Bionic Radiologist will thus help avoiding missed care opportunities. Read more…
Kidney Injury after Intravenous versus Intra-arterial Contrast Agent in Patients Suspected of Having Coronary Artery Disease: A Randomized Trial
Eva Schönenberger, Peter Martus, , Elke Zimmermann, Rudolf Tauber, Michael Laule and Prof. Marc Dewey teamed up to compare intravenous versus intra-arterial contrast agent administration in relationship to AKI and analyze the association between AKI and chronic kidney disease.
The results and conclusion:
A total of 320 participants (163 [50.9%] women; mean age, 60 years ± 11) were included. Baseline eGFR did not differ between the CT angiography group (84.3 mL/min/1.73 m2 ± 17.2) and the catheterization group (87.1 mL/min/1.73 m2 ± 16.7) (P = .14). AKI occurred in nine of 161 participants in the CT angiography group (5.6%; 95% CI: 3%, 10%) and in 21 of 159 participants in the catheterization group (13.2%; 95% CI: 9%,19%) (relative risk, 2.4; 95% CI: 1.1, 5.0; P = .02). Also in the subgroup of participants without obstructive CAD, in those not requiring coronary interventions, AKI was more common in the catheterization group (11.9%; 95% CI: 8%, 19%) than in the CT angiography group (4.3% [95% CI: 2%, 9%]; difference, 7.7% [95% CI: 1.3%, 14.1%]; relative risk, 2.8 [95% CI: 1.1, 7.0]; P = .02). Obstructive CAD (odds ratio [OR]: 2.7 [95% CI: 1.1, 6.6]; P = .02), femoral catheter access (OR: 2.5 [95% CI: 1.1, 5.6]; P = .04), and cine ventriculography were associated with AKI (OR: 2.3 [95% CI: 1.0, 4.9]; P = .03). In multivariable analysis, the presence of postcontrast AKI was associated with chronic kidney disease (hazard ratio: 12.4 [95% CI: 4.5, 34.6]; P < .01).
Acute kidney injury was more common after cardiac catheterization than after CT angiography in this prospective randomized study of patients suspected of having coronary artery disease.

The project “Fractal Analysis of Myocardial Ischemia” of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) applied successfully for a Mercator-Fellow – the first ever in Radiology. Kakuya Kitagawa, MD, PhD, of the Department of Radiology at the Mie University Hospital in Japan will be supporting the project with his expertise and his international perspective.
The DFG-project “Fractal Analysis” was proposed by Prof. Dr. Marc Dewey and Dr. Florian Michallek from the department of Radiology at Charité Universitätsmedizin Berlin. The researchers want to develop a method to examine the causes of chronic ischaemic heart disease in a better and non-invasive way. They investigate if fractal analysis is a comprehensive perfusion analysis method (Figure 1). “We are looking forward to the scientific contribution of Kakuya to this project as he is one of the most renown experts on multimodality myocardial perfusion imaging worldwide.” says Prof. Dewey and Dr. Michallek explains “The Mercator-Fellowship Programme allows on the one hand to involve the distinguished expertise of Prof. Kitagawa for the project and on the other hand to synthesise a highly interesting and multi-centric dataset.
