With the recent introduction of multi-slice CT which acquire four image slices at the same time (which will increase to 16 image slices in the near future) the possible size of the generated image stack has increased tremendously. Traditional cine mode explorations of the image stack are rendered impractical by the sheer quantity of possible 1000 image(More)
Two patients carrying an active subretinal implant with extra-ocular parts were examined by high-resolution CT. Cranial scans were acquired in the primary position and in eight additional directions of gaze with eyes open and closed to demonstrate the mobility of the eyeball and the implant within the orbital cavity. Three-dimensional images were(More)
OBJECTIVE The aim of this study was to investigate image quality and diagnostic accuracy in detecting coronary artery lesions using a 16-MDCT scanner. MATERIALS AND METHODS Thirty-seven patients (28 men, nine women) underwent unenhanced helical CT and MDCT angiography of the coronary arteries. After patients received oral beta-blocker medication, CT scans(More)
AbstRAct Economists have long been interested in the productivity effects of infrastructure investment, and this research has been an important input into budget allocations for investment in transport infrastructure. This chapter analyses the macroeconomic productivity effects of road investment in Western European countries. This chapter shows that the(More)
BACKGROUND Overdiagnosis of bronchopulmonary carcinoid tumors together with overtreatment can cause serious postoperative consequences for the patient. We report of a patient with a typical bronchopulmonary carcinoid tumor, which was initially misdiagnosed and treated as an adenocarcinoma of the lung. GnrH receptors and the associated(More)
The International Energy Agency (IEA), an autonomous agency, was established in November 1974. Its primary mandate was – and is – twofold: to promote energy security amongst its member countries through collective response to physical disruptions in oil supply, and provide authoritative research and analysis on ways to ensure reliable, affordable and clean(More)
hardware/software co-design approach is proposed to ease and accelerate the development for different experiments. In the uniform system design, application-specific computation is to be implemented as customized hardware co-processors, while the embedded PowerPC processor takes charge of flexible slow controls and transmission protocol processing.
BACKGROUND Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation.In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection (Grade 03 R) and cardiac allograft vasculopathy. Thus we compared multi-slice computed tomography and(More)
[1] The time-variable structure of Ganymede's magnetosphere is studied by means of resistive MHD simulations. Using the magnetometer measurements of the Galileo spacecraft in the first few Ganymede flybys as examples, we find that the plasma flow pattern inside the Ganymedian magnetosphere could be subject to significant changes. Furthermore, the boundary(More)
