OBJECTIVES Vascular endothelial function and common carotid artery intima-medial thickness (CCA-IMT) are well-established surrogate markers for early atherosclerotic disease, which accounts for 30-40% of excess mortality in rheumatoid arthritis (RA) patients. Our aim was to investigate whether long-term treatment with anti-tumour necrosis factor (TNF)alpha(More)
Imaging findings in a 52-year-old woman with proven proliferative myositis are described. US revealed preservation of continuous muscle bundles and patchy areas of hyperechogenicity, containing hypoechoic lines. MRI showed at T2-w sequences an ill-defined, hyperintense, intramuscular lesion, containing isointense lines. Subtotal enhancement, a nonenhancing(More)
This work demonstrates the use of a fast and precise methodology for evaluating myocardial and liver iron status in multitransfused thalassemic patients by means of a fast T(2) (*) quantitative MRI (T(2) (*)qMRI) technique. Myocardial and liver T(2) (*) values were calculated in 48 thalassemic patients and 21 normal subjects on a 1.5T MRI system using a(More)
AIM To evaluate the potential of SPECT myocardial perfusion imaging (MPI)-computed tomography coronary angiography (CTCA) hybrid fusion imaging to improve the diagnostic performance of cardiac SPECT/MPI and CTCA alone in order to act as more accurate gate keeper to further investigation invasive or not. METHODS AND RESULTS Twenty-five patients were(More)
BACKGROUND In order to evaluate the elastic behavior of the abdominal aortic aneurysm (AAA), the distribution of aortic deformation during the cardiac cycle is measured. Moreover, the distensibility of the AAA composite structure consisting of the AAA wall and the intraluminal thrombus (ILT), as well as that of the adjacent non-aneurysmal aortic segment(More)
Abdominal aortic aneurysmal disease is a major health problem with rupture representing its main complication accompanied by great mortality. Elective repair is currently performed with mortality rates <3%, based upon size or expansion rate, with a recommended threshold of 5.5 cm maximum diameter or >1cm/year enlargement. It is well established that even(More)
The purpose of this study was to examine the accuracy of the stereological method for estimating right ventricular parameters on cine MR images. The end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fraction (EF) were estimated in 19 consecutive patients with suspected or known coronary artery disease employing the(More)
