The combined use of shoulder arthrography with MR and CT imaging offers distinct advantages over conventional nonarthrographic imaging techniques. The improved contrast and joint distension afforded by direct arthrography optimize evaluation of various intra-articular structures and help to define subtle abnormalities and distinguish normal variants from true shoulder pathology. In this article, we review the rationale and basic approaches to shoulder arthrography as well as the imaging appearance of the normal shoulder, anatomical variants, and pathology highlighted by this technique.
Vapor−liquid equilibria for dendritic-polymer solutions were obtained using a classic gravimetric-sorption
method; the amount of solvent absorbed by the dendrimer was measured as a function of solvent vapor
pressure. Three series of dendrimers, each with the same tertiary amine core structure, but different
surface groups, were investigated in a variety of organic solvents in the range 50−75 °C. The dendrimer
surface groups were dodecylamines, octadecyl amides, and polyisobutylene. Solvent absorption depends
strongly on dendrimer composition and generation number.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
