The following question has been sent by Sofiane Hadjadj, MD, clinical research, Canada: hi, we have just aquired the dual source ct, and I am very impressed by the quality of images for coro ct even with high calccium scoring, my question is regarding the EKG editing, are their any rules … Read more

Dual Source coronary CT angiography (cCTA) is not only faster than previous scanner generations and less invasive than cardiac catheterization, it also may in some cases more realiably localize proximal bypass anastomoses and provide more anatomic information crucial to the success of potential redo coronary artery bypass graft (CABG) surgery. Dual … Read more

Case history A 65-year-old female presents with unclear chest pain and dyspnea. The symptoms are nonspecific. Initial troponin test and ECG are normal. Question Is there an acute cardiovascular condition requiring immediate intervention? Is there evidence of the cause of chest pain? Diagnosis / Differential diagnosis The most important and potentially lifethreatening causes of chest … Read more

In recent studies at Munich University, the combined Dual Source CT protocol for chest pain assessment showed a high sensitivity for the cause of chest pain. Due to its robust image quality even in high heart rates DSCT greatly improves diagnostic accuracy. In cases of acute chest pain, the initial focus … Read more

The Dual Source CT protocol for chest pain assessment proved to be a helpful tool offering a fast diagnostic workup and patient triage. The heart rate insensitivity of DSCT further increases the diagnostic accuracy of the method by improving coronary artery assessment in acutely ill patients. The initial symptoms of the … Read more

Abstract Objective. The purpose of this study was to evaluate the effect of mean heart rate and heart rate variability on the image quality of dual-source CT coronary angiography. Subjects and methods. Eighty patients underwent dual-source CT coronary angiography. Thirteen data sets were reconstructed in 5% steps from 20–80% of the R-R … Read more
