Purpose: To assess the diagnostic performance of dual-energy dual-source computed tomography (CT) in the detection of endoleaks after endovascular abdominal aortic aneurysm (AAA) repair. Materials and Methods: This study was local ethics board approved, and written informed consent was obtained from all patients. One hundred eighteen patients (21 women, 97 men; mean age, … Read more

Purpose The purpose of this study was to assess the radiation dose and associated image noise of previously suggested calcium scoring protocols using dual-source CT. Methods One hundred consecutive patients underwent coronary calcium scoring using dual-source CT. Patients were randomly assigned to five different protocols: retrospective ECG-gating and tube current reduction to … Read more

Abrar Hayat, Kuwait, has sent the following question: dose reduction in DSCT compared to 64-MDCT: Other venders claim that they have upgraded their 64-MDCT with new applications so that the dose is reduced by 50 % compared to their regular 64-MDCT! how does the DSCT compare to those? Am I going to … Read more

Objektive: To compare the image quality of mono- versus bisegment reconstruction algorithms for dual-source computed tomography coronary angiography (CTCA). Materials and methods: Eighty consecutive patients (27 women; average age, 60 +/- 12 years) were randomly assigned to 2 different CTCA scanning protocols: 40 patients (group A) underwent dual-source CTCA with a … Read more

The purpose of this study was to investigate the effect of low kilovoltage dual-source computed tomography coronary angiography (CTCA) on qualitative and quantitative image quality parameters and radiation dose. Dual-source CTCA with retrospective ECG gating was performed in 80 consecutive … Read more
