OBJECTIVE The purpose of this study was to evaluate the efficiency of automatic bone removal in dual-energy CT angiography (CTA) of the trunk. SUBJECTS AND METHODS Nineteen patients underwent dual-energy CTA of the trunk (tube A, 140 kV; tube B, 100 kV). In addition to the dual-energy dataset, an image equivalent to that of a standard 120-kV single-energy(More)
BACKGROUND Today's gold standard for diagnostic imaging of inflammatory diseases of the paranasal sinus is computed tomography (CT). PURPOSE To evaluate diagnostic sensitivity and radiation dose of an ultra-low dose dual-source CT technique. MATERIAL AND METHODS Paranasal sinuses of 14 cadaveric heads were independently evaluated by two readers using a(More)
OBJECTIVE To investigate the bolus geometry in high-pitch CT angiography (CTA) of the aorta without ECG synchronisation in comparison to single-source CT. METHODS Overall 160 consecutive patients underwent CTA either in conventional single-source mode with a pitch of 1.2 (group 1), or in dual-source mode with a pitch of 3.0 (groups 2, 3 and 4) using(More)
PURPOSE The purpose of this study was to objectively analyze motion artifacts on thoracic computed tomography (CT) with dual-source high-pitch and single-source techniques when using a no-breath-hold technique to examine patients who have difficulty complying with breath-holding instructions. MATERIALS AND METHODS A total of 120 patients who received CT(More)
OBJECTIVES To evaluate the impact of endovascular embolisation therapy in men with erectile impotence due to veno-occlusive dysfunction. METHODS We retrospectively evaluated 29 patients with a history of erectile impotence due to veno-oclusive dysfunction confirmed by pharmacocavernosometry and cavernosography. All underwent endovascular embolisation(More)
RATIONALE AND OBJECTIVES Benefits of iterative reconstruction (IR) algorithms combined with dose-reduction techniques have been shown at computed tomography pulmonary angiography (CTPA) in several medium to small patient collectives. In this study, we performed a systematic comparison of image quality to combinations of reduced tube current (RC) and IR for(More)
BACKGROUND We report the results of our single center series of patients with chronic mesenteric ischemia (CMI) to determine the role of stenting in the management of patients. PATIENTS AND METHODS We retrospectively reviewed all patients with CMI treated endovascularly with stent revascularisation from January 2008 to January 2011.CMI diagnosis was made(More)
PURPOSE Robotic guided stereotactic radiosurgery has recently been investigated for the treatment of atrial fibrillation (AF). Before moving into human treatments, multiple implications for treatment planning given a potential target tracking approach have to be considered. MATERIALS & METHODS Theoretical AF radiosurgery treatment plans for twenty-four(More)
Sliding-gantry computed tomography offers an interesting variety of treatment options for emergency radiology and clinical routine. The Frankfurt 2-room installation provides an interdisciplinary, multifunctional, and cost-effective concept. It is based on a magnetically sealed rail system for the permanent movement of the gantry between 2 adjacent rooms(More)
BACKGROUND  Inferior vein graft patency after coronary artery bypass grafting (CABG) is attributed to various factors. Venous valves may limit flow, cause thrombus formation, and diminish diastolic backflow. The aim of our study was to compare clinical outcome and midterm patency rate of valvulotomized vein grafts and arterial grafts in patients undergoing(More)
