Written By: Malacostracan, any member of the more than 29,000 species of the class Malacostraca (subphylum Crustacea, phylum Arthropoda), a widely distributed group of marine, freshwater, and terrestrial invertebrates. Lobsters, crabs, hermit crabs, shrimp, and isopods are all malacostracan crustaceans.
As a result, the cost per technical RVU for the two modalities was reversed, with a low cost basis ($17.69) for MR imaging and a nearly fivefold higher cost basis ($89.03) for interventional radiology. Indeed, it was this observation that led us to compare costs on a per examination basis.
Three published UK studies have been reviewed in which the cost per fraction of radiotherapy was estimated to lie between 22 pounds and 38 pounds in 1989.
