Discuss hot topics or ask the expert your specific question about Dual Source CT (DSCT) and Flash scanning in practice.

Two interesting questions about CT in pediatrics have been asked on DSCT.com some time ago. As Dr. Hyun Woo Goo, who is an expert in pediatrics, recently joined the DSCT expert community, DSCT.com asked him to comment on these questions as well. Read his answers here. The following questions … Read more

The following question has been sent by Patrick, CT Tech: Our facilty is currently operating a siemens Definition Scanner. I was hoping you could recommend some reading material on Dual Source CT. Also some info on how to reduce radiation exposure. Ralf Bauer, MD, Clinic of the Goethe University, Frankfurt, Germany: Dear … Read more

Between November 2009 and February 2010 users of SOMATOM Definition, SOMATOM AS and SOMATOM Flash submitted over 270 CT images to the international CT image contest. The contest aims on choosing the best CT images acquired at the lowest radiation dose. In February, the jury starts to evaluate the images. Aside … Read more

Objective: In supraaortic vessels, bone subtracted maximum intensity projections make the evaluation of computed tomographic angiography (CTA) datasets easier and faster. Dual energy CT can be used for bone removal without user interaction. The purpose of this study was to compare the results of conventional and dual energy-based bone removal. Materials … Read more

This fourth article of our Dual Energy series gives an overview of the most important clinical applications of Dual Energy, including color coding of contrast material, perfusion imaging, angiography, and differentiation of renal stones and tendons/ligaments. Read more

Feb 21, 2010 to Feb 24, 2010. This 4-day course is devoted to cutting edge cardiac imaging. Participants will have an opportunity to learn the basics of cardiac CT and MRI acquisition and interpretation with interactive workstation reviews of 50 cardiac CT exams. Read more

This third article of our Dual Energy-series focuses on the technical implementation of Dual Energy technology. For Dual Energy scanning, the tube potentials are mostly set to 140 and 80 kVp to obtain the largest spectral difference. Weighted average images are calculated by the image reconstruction system to resemble normal 120 … Read more

Electro-cardiogram (ECG)-gated dual energy computed tomography (DECT) of the heart may enable spectral analysis of the myocardium for areas of decreased blood supply in addition to morphological assessment for coronary artery stenosis. We used DECT for evaluating a 49-year-old woman with known coronary artery disease and new onset chest pain. She … Read more
