There are only a few reports on the diagnostic accuracy, and the technical and clinical feasibility, of multidetector CT (MDCT) in infants with congenital heart disease (CHD). To evaluate the image quality and radiation dose of DSCT in babies with CHD. From November 2006 to November 2007, 110 consecutive infants with CHD referred for pre- or postoperative(More)
For coronary artery visualization, retrospective ECG-gated acquisition by dual-source computed tomography (DSCT) was superior to spiral non-ECG-gated acquisition in a paediatric population of congenital heart disease (CHD) patients. However, retrospective cardiac CT is associated with substantial radiation doses to the patient. Recently, DSCT with(More)
OBJECTIVE The objective of our study was to show the feasibility of coronary CT using low kilovoltage (80 kV) combined with ECG-pulsed tube current modulation in selected patients. CONCLUSION This study showed the combined effect of lowering the kilovoltage setting (80 kV) and using an automatic modulation technique (ECG-pulsed tube current modulation)(More)
Reconstruction of cardiac computed tomography (CT) images is challenging when the heart rate is higher than 65 beats per minute (bpm). The optimal reconstruction time is often found to be at the end-systolic phase, but image quality remains uncertain. Using dual-source (DS) CT and 83-ms temporal resolution, we evaluated the robustness of the temporal window(More)
OBJECTIVES Surgical management of airway compression of vascular origin requires an accurate analysis of anatomy and various mechanisms of compression. This study assessed the usefulness of 3-dimensional computed tomographic scanning in the preoperative and postoperative evaluation of airways compression in a pediatric population. METHODS Thirty-seven(More)
OBJECTIVES The goal of this study was to evaluate the diagnostic accuracy of 64-slice computed tomography (CT) to identify coronary artery disease (CAD) in patients with complete left bundle branch block (LBBB). BACKGROUND Left bundle branch block increases risk of cardiac mortality, and prognosis is primarily determined by the underlying coronary(More)
AIMS We evaluated the accuracy of 64-slice computed tomography (CT) to identify ischaemic aetiology of heart failure (IHF). METHODS AND RESULTS Ninety-three consecutive patients in sinus rhythm with dilated cardiomyopathy but without suspicion of coronary artery disease (CAD) were enrolled when admitted for angiography. Accuracy of CT to detect(More)
PURPOSE To assess the feasibility of low-kilovoltage (ie, 80-kV) chest computed tomography (CT) protocols for adults and the effect of such protocols on image quality and iodine dose. MATERIALS AND METHODS Preliminarily, 90 patients (30 women, 60 men; mean age, 59 years) requiring contrast material-enhanced chest CT were randomly assigned to one of three(More)
OBJECTIVE Recent experimental and limited clinical studies have demonstrated the usefulness of delayed enhancement multislice computed tomography (MSCT) for assessing myocardial infarct size (IS) and transmurality. The aim of this study is to compare MSCT enhancement patterns immediately after coronary angiography (CAG) in an acute myocardial infarction(More)
We compared 16-slice computed tomography with intravascular ultrasound in the detection of unstable component characteristics of nonstenotic plaque responsible for acute coronary syndrome. Computed tomography accurately assessed plaque eccentricity, calcification, and remodeling, and intraplaque hypodensity correlated with intravascular ultrasound(More)
