DSCT Experts - The International Dual Source CT Community

Abstract
Objectives
The aim of this study was to assess the value of multislice computed tomography (CT) for the assessment of valvular abnormalities in patients with infective endocarditis (IE) in comparison with transesophageal echocardiography (TEE) and intraoperative findings.

Background
Multislice CT has recently shown promising data regarding valvular imaging in a 4-dimensional …

Abstract

Objective: Triple phase (non-contrast, arterial, venous) single energy CT (SECT) scans are often used to monitor patients after endovascular thoracoabdominal aortic aneurysm repair. We investigated the feasibility of replacing non-contrast and arterial phase SECT scans with a single arterial phase dual energy CT (DECT) scan and generating virtual non-contrast images.  

Methods: …

• aortic aneurysm
• computed tomography
• dual energy
• endovascular repair
• virtual non-contrast

Abstract

We evaluated an algorithm for automatic selection of the cardiac phase with the least motion for image reconstruction at coronary computed tomography (CT) angiography (CCTA).

We analyzed data of 100 patients (49 female, mean age 59 years) who had undergone retrospectively ECG-gated CCTA. Two experienced observers visually identified the most suitable …

A41-year-old woman was admitted to the Medical University of South Carolina cardiology service with new-onset atrial fibrillation, with chest tightness, shortness of breath, and a nonproductive cough. As a child, she had a congenital bicuspid aortic valve with severe aortic stenosis that initially required commissurotomy, a bioprosthetic valve replacement at …

History
A 55-year-old male patient (heart rate 75 bpm, body mass index 26.0 kg/sqm) suffered from progredient physical inefficiency and atypical chest pain since several months. Thoracic CT (non-ECG-gated) raised the suspicion of thrombosis of the innominate vein. There was also found a left mediastinal tubular contrast-enhanced structure which was suspected …
