Charité Cardiac CT Course
Even Aunt Minnie recommends it! The Charité Universitätsmedizin Berlin radiology department is hosting a hands-on cardiac CT course (www.ct-kurs.de) from 16. to 20. September, and a limited number of spaces are still available.
About the course:
There have been dramatic technical advances in computed tomography for imaging of the heart and particularly the coronary arteries. During the course you will had 100 hands-on cardiac CT cases with invasive angiography correlation. Also, overview lectures on patient preparation and scanning, as well as image reconstruction and reading will be given. Also see this publication on improvement of skills and knowledge by a hands-on cardiac CT course: https://www.ncbi.nlm.nih.gov/pubmed/20084596

“Wir sind sehr Stolz!”
Congratulations to the Berlin University Alliance which was selected after peer review and onsite evaluations by DFG and Wissenschaftsrat for funding in the Excellence Strategy Program on July 19.
Professor Dewey is supporting the Alliance as the Charité representative on the Steering Committee fostering knowledge exchange and in the research forums led by Professor Christine Ahrend from TU Berlin. A country-wide map of funding of the Excellence Strategy can be found here.
Let’s keep up the excellent work!
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, Maria Bosserdt, 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.

Summer excursion to Prenzlauer Berg
The Dewey AG is not only researching the hottest topics of radiology, but we’re also curious explorers of our city and our neighbourhood of Prenzlauer Berg. The home district of Prof. Dewey was part of a guided summer excursion with many interesting and little known facts about this very historical part of Berlin.
It was a great saturday, we are looking forward to the next excursion!
The latest scientific release from Mr. Robert Haase by the british Medical Journal on the topic of “Diagnosis of obstructive coronary artery disease using computed tomography angiography in patients with stable chest pain depending on clinical probability and in clinically important subgroups: meta-analysis of individual patient data”.
The objective was to determine whether coronary computed tomography angiography (CTA) should be performed in patients with any clinical probability of coronary artery disease (CAD), and whether the diagnostic performance differs between subgroups of patients. Read more about it here.

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.
