The development of multidetector row computed tomography (MDCT) has led to the acquisition of true isotropic voxels that can be postprocessed to yield images in any plane of the same resolution as the original axially acquired images. This, coupled with rapid MDCT imaging during peak target organ enhancement has led to a variety of means to review ...

Imaging has always been a strong driving force in the treatment and diagnosis of epilepsies. The development of new magnetic resonance-acquisition techniques (e.g., parallel imaging, less motion-sensitive sequences, enhanced contrasts), as well as the growing number of postprocessing tools, has led to an apparent decline in the number of cryptogeni...

HintergrundMit der sauerstoffbasierten Lungen-MRT lässt sich die Lungenfunktion in Differenzbildern von Akquisitionen unter Raumluft- und Sauerstoffatmung darstellen. In dieser Studie soll analysiert werden, wie die Berechnung dieser Differenzbilder von der verzögerten Signaländerung nach dem Atemgaswechsel abhängt.MethodenZehn gesunde Probanden wu...

Multislice computed tomography angiography (CTA) has been found feasible for the evaluation of visceral vasculature. The development of multislice technology has overcome past limitations. First, the faster scanning speed increases volume coverage during a single breath-hold and improves the exploitation of contrast medium. Second, the better spati...

Nichtinvasive Verfahren wie die CTA verdrängen zunehmend die DSA bei der präoperativen Abklärung von Patienten mit Karotisstenosen. Die zuverlässige Beurteilung von Karotisstenosen erfordert ein dediziertes und standardisiertes Untersuchungsprotokoll, das für unterschiedliche CT-Scanner angepasst werden muss. Eine Darstellung der für die Therapieen...

Tissue transition projection (TTP) represents a three-dimensional reconstruction technique for volumetric image data sets. To demonstrate the principle characteristics of TTP, a simple phantom consisting of two pipes with a simulated, wall-adherent polyp was scanned with spiral CT, and images were reconstructed by means of volume rendering for both...
