Case history 81-year-old male presented for follow-up exam to indicate convalescence progress. 6 weeks before, he had been delivered for coiling and stent implantation due to ruptured aneurysm. He had complained about pain in the lower abdominal region. A day after the stent implantation a type II endoleakage had appeared. 4 … Read more

The objective was to prospectively investigate the diagnostic accuracy of high-pitch (HP) dual-source computed tomography coronary angiography (CTCA) compared with catheter coronary angiography (CCA) for the diagnosis of significant coronary stenoses. Read more

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 … 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

Abstract To assess the prevalence and morphological characteristics of coronary artery ectasia (CAE) with CT coronary angiography (CTCA) in comparison to conventional catheterangiography (CCA), Dual-source CTCA examinations from 677 consecutive patients (223 women; median age 57 years) were retrospectively evaluated by two blinded observers for the presence of CAE defined as … Read more
