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.
The average costs were higher for those who received a CT scan ($300) than they were among those who received an ultrasound performed by either an emergency department physician ($150) or a radiologist ($200), that study found.he average costs were higher for those who received a CT scan ($300) than they were among those who received an ultrasound performed by either an emergency department physician ($150) or a radiologist ($200), that study found.
