OBJECTIVE In a previous in vitro study we have demonstrated that atherosclerotic plaque components can be characterized with multidetector computed tomography (MDCT) based on differences in Hounsfield values (HV). Now we evaluated the use of MDCT in vivo to characterize and quantify atherosclerotic carotid plaque components compared with histology as(More)
BACKGROUND AND PURPOSE Besides the severity of carotid artery stenosis, atherosclerotic plaque composition is an important determinant of cerebral symptoms. We analyzed the relationship between the composition of the atherosclerotic plaque at the carotid artery bifurcation and ipsilateral ischemic cerebral lesions on MR imaging. METHODS Forty-one patients(More)
AIMS To describe long-term survival, clinical outcome and ventricular systolic function in a longitudinally followed cohort of patients after Mustard repair for transposition of the great arteries (TGA). There is serious concern about the long-term outcome after Mustard repair. METHODS AND RESULTS This longitudinal single-centre study consisted of 91(More)
BACKGROUND Prospective data on long-term survival and clinical outcome beyond 30 years after surgical correction of tetralogy of Fallot are nonexistent. METHODS AND RESULTS This longitudinal cohort study consists of the 144 patients with tetralogy of Fallot who underwent surgical repair at <15 years of age between 1968 and 1980 in our center. They are(More)
PURPOSE This study aims to compare image quality, radiation dose, and the influence of the heart rate on image quality of high-pitch spiral coronary computed tomography angiography (CCTA) using 128-slice (second generation) dual-source CT (DSCT) and a 192-slice DSCT (third generation) scanner. MATERIALS AND METHODS Two consecutive cohorts of fifty(More)
Case A 21-year-old man underwent stent implantation (8Z45CP stent on 18 mm BiB-balloon, Numed, Hopkinton, NY) for a recurrent aortic obstruction, after previous repair of an aortic interruption type A. At the age of two weeks after birth an end-to-side anastomosis of the descending aorta onto the distal arch (left subclavian artery) was performed. Diagnosis(More)
PURPOSE to evaluate the influence of bone-conduction in the MR environment compared to a standardized acoustic environment. MATERIALS AND METHODS Acoustic noise is an unwanted side effect of MRI that is commonly tackled with passive hearing protection. In an MR scanner, however, with the patient completely surrounded by the MR sounds and in close contact(More)
