OBJECTIVES The hypothesis that endovascular treatment with covered stents has equal risks but higher efficacy than bare-metal stents (BMS) in long femoropopliteal artery disease was tested. BACKGROUND Although endovascular treatment of short superficial femoral artery lesions revealed excellent results, efficacy in long lesions remains unsatisfactory. (More)
BACKGROUND It is not known whether high-risk plaque, as detected by coronary computed tomography angiography (CTA), permits improved early diagnosis of acute coronary syndromes (ACS) independently to the presence of significant coronary artery disease (CAD) in patients with acute chest pain. OBJECTIVES The primary aim of this study was to determine(More)
PURPOSE The hypothesis that covered stents are superior to bare-metal stents (BMS) in long femoropopliteal artery disease was tested. The one-year results of the VIASTAR trial revealed a patency benefit of covered stents in the treatment-per-protocol (TPP) analysis only. METHODS A prospective, randomized, single-blind, multicenter study evaluated 141(More)
BACKGROUND AND PURPOSE The noninvasive identification of plaque types prone to cause symptomatic disease is of great interest to improve the effectiveness of surgical or interventional management. The purpose of the present prospective pilot study was to evaluate the association between the results of imaging-the novel sonography technique B-flow imaging(More)
OBJECTIVE The purpose of this study was assessment of the long-term outcome of fibroid-associated quality of life among patients treated with uterine fibroid embolization. MATERIALS AND METHODS A retrospective follow-up cohort study included all patients described in a 2006 publication. Analysis was performed with a questionnaire consisting of 49(More)
PURPOSE To determine the association between nonalcoholic fatty liver disease (NAFLD) and the presence of high-risk coronary atherosclerotic plaque as assessed with coronary computed tomographic (CT) angiography. MATERIALS AND METHODS This study was approved by the local ethics committees; informed consent was obtained. Patients randomized to the coronary(More)
INTRODUCTION The aim of this study was to evaluate the feasibility and accuracy of commercially available software directly implemented on the ultrasound scanner for automated measurement of the intima-media thickness (IMT) of the common carotid artery on source images. MATERIALS AND METHODS Measurements were performed on a GE Vivid 3 ultrasound scanner.(More)
PURPOSE Obesity promotes pancreatic and breast cancer progression via mechanisms that are poorly understood. Although obesity is associated with increased systemic levels of placental growth factor (PlGF), the role of PlGF in obesity-induced tumor progression is not known. PlGF and its receptor VEGFR-1 have been shown to modulate tumor angiogenesis and(More)
OBJECTIVES To evaluate whether iterative reconstruction algorithms improve the diagnostic accuracy of coronary CT angiography (CCTA) for detection of lipid-core plaque (LCP) compared to histology. METHODS AND MATERIALS CCTA and histological data were acquired from three ex vivo hearts. CCTA images were reconstructed using filtered back projection (FBP),(More)
OBJECTIVE The purpose of this study was to compare CT angiography (CTA) and MR angiography (MRA) for the detectability of 75% and 95% stenoses in phantoms using six different stents. MATERIALS AND METHODS Six different stents (Expander, Hemobahn, SelfX, Smart, Symphony, and Wallstent) were inserted into tubes filled with contrast agent (ioversol or(More)
