The routine staging work-up for renal cancer includes a contrast-enhanced multiphasic spiral CT and a chest radiograph. If there is doubt regarding the presence and extent of (supradiaphragmatic) IVC thrombus, MR imaging should be performed. Dynamic contrast-enhanced MR imaging should be used in place of CT in any patient with severe renal dysfunction,(More)
OBJECTIVE To evauluate our novel ultrasound model for measurement of optic nerve sheath diameter (ONSD) and determine the intra- and inter-operator variability associated with this technique. METHODS We conducted ten measurements of ONSD per model amongst eight different models with a single experienced operator to examine intra-operator variability.(More)
BACKGROUND AND PURPOSE 3D time-of-flight MR angiography (3D TOF MRA) may be used as noninvasive alternative to digital subtraction angiography (DSA) for the follow-up of patients with intracranial aneurysms treated with Guglielmi detachable coils (GDCs). We aimed to determine the influence of aneurysm size and location on diagnostic accuracy of 3D TOF MRA(More)
Computed tomography (CT) and magnetic resonance (MR) imaging are first line modalities in the evaluation of patients with adrenal gland masses, and have the potential to be very accurate for the localization of adrenal gland masses in patients with diseases associated with hyperfunctioning conditions of the adrenal gland. Both CT and MR imaging allow a(More)
The Very High Efficiency Solar Cell (VHESC) program is developing integrated optical system PV modules for portable applications that operate at greater than 50 percent efficiency. We are integrating the optical design with the solar cell design, and have entered previously unoccupied design space. Our approach is driven by proven quantitative models for(More)
OBJECTIVE Does the recently introduced 3D angiography provide additional information beyond standard angiography (DSA) for the diagnosis of cerebral aneurysms? METHODS During a 3-months period DSA and 3D-angiography were performed in 40 patients harbouring a total of 49 aneurysms. Vascular regions that presented an aneurysm diagnosed by DSA were(More)
Das diagnostische Routine Work-up für das Nierenzellkarzinom-Staging beinhaltet ein mehrphasisches Abdomen Spiral-CT und ein Thoraxröntgen. Bei unklarem Spiral-CT Befund in der Fragestellung intravenöse Tumorausdehnung kann die kontrastmittelverstärkte MRT eine wertvolle diagnostische Alternative darstellen. Die primären Indikationen zur renalen MRT(More)
