Gadodiamide injection for Enhancement of MRI in the CNS. Applications, dose, field and time dependence.

Popular Abstract in Swedish Magnetresonanstomografi (MRT) är en metod för framställning av bilder av kroppen och av sjukliga förändringar i kroppen. När metoden introducerades ansågs den utomordentligt goda inbyggda vävnadskontrasten vara tillräcklig för att särskilja olika sjukliga förändringar, speciellt i hjärnan. Det har emellertid visat sig att förmågan att upptäcka sjukliga förändringar är oAims of the study The aims of this study using Gadodiamide injection were to investigate: · Whether Gadodiamide injection was comparable to Gd-DTPA for the enhancement of CNS lesions. · The contrast effect at different field strengths. · The effective time-window for the enhancement of blood-brain barrier damage. · The relations between the concentration of contrast agent and enhancement in p

Laminar Friction Factors and Colburn Factors for Ducts with Advanced Boundary Conditions

Ducts of various geometrical cross sections appear extensively in engineering applications like heat exchangers. In the available literature analytical, numerical and experimental data are available for the friction factor and the Colburn factor for a variety of thermal boundary conditions. Results for fully developed cases are commonly available, but also for the thermally and hydrodynamically de

Distribution System Component Failure Rates and Repair Times - An Overview

This paper presents the results of a literature search for publications containing failure rates and repair times, based on operational experience, for distribution system components that are critical to the reliability of a distribution system. Furthermore, component failure rates found are compared with the conclusions drawn from a previously conducted literature search.
