Transmission measurement is recommended in order to accurately correct for attenuation in myocardial single-photon emission tomography (SPET) studies. It is important that transmission studies are artefact-free, otherwise the attenuation-corrected SPET studies may also be affected. An assumption in transmission studies is that the measured transmis...

Une évaluation de la résolution spatiale de deux sondes linéaire et matricielle est réalisée sur fantôme en testant plusieurs paramètres (fréquence d'émission, modes harmonique, composite, focale,...). Celle-ci met en évidence que la sonde matricielle a une meilleure résolution axiale, latérale et azimutale que la sonde linéaire avec une épaisseur ...

We assessed possible advantages of the use of fluid-attenuated inversion-recovery (FLAIR) sequences with magnetisation-transfer contrast (MTC) over conventional FLAIR images. We carried out cranial MRI at 1 tesla on 50 patients with both sequences. In nine patients with multiple sclerosis (MS) we performed a quantitative comparison of the two seque...

Objects may in the future become enhanced with new digital properties and information-communication capabilities, thus turning them into Hyper-Objects. This paper describes an approach towards defining Hyper-Objects, and examines to what extent their advance affects our existing lifestyle patterns.

A mixture of [2H7]-geraniol, [2H7]-nerol, [2H7]-linalool and [2H7]-α-terpineol was prepared for use as internal standards in a rapid and accurate analytical method, employing gas chromatography–mass spectrometry (GC/MS), to determine the concentration of geraniol, nerol, linalool and α-terpineol in wine. The method avoids the possible formation, de...

Verursachen verschiedene, in der Orthopädie gebräuchliche, Metallegierungen messbar unterschiedliche Artefakte (Störsignale) in der Kernspintomographie? Gibt es artefaktreduzierende Sequenzen? Wird durch das Hochfrequenzmagnetfeld eine messbare Anziehungskraft auf die einzelnen Legierungen ausgeübt? Untersucht wurden 12 Metallegierungen (Allergiepl...

Das ABBI (“advanced breast biopsy instrumentation”)-System steht seit kurzem zur diagnostischen Exzisionsbiopsie kleiner, nicht palpabler Herde der Mamma zur Verfügung. Diese Biopsiemethode wurde zwischen 1.1.1998 und 31.3.1999 an 40 Patientinnen mit suspekten Mikroverkalkungen (n=25), neu aufgetretenen Verdichtungen (n=11) sowie einer Kombination ...

Interpretation of studies from all imaging modalities requires a knowledge of the possible pitfalls that may occur due to normal variation, artefacts and processes which may mimic pathology. The applications and use of not only 18-fluoro-2-deoxyglucose but also l-[methyl-11C] methionine positron emission tomography (PET) are widening and it is time...

Speciation is required for obtaining information on chemical reactivity, toxicity and bioavailability of an element. In this work, a novel analytical speciation methodology, using a dual radiotracer technique is described. The approach is illustrated with the speciation of 99 Tc , a pure β −-emitter, in spinach plants. The actual leaf concentration...
