The emphasis is on anatomical detail; using endogenous contrast mechanisms to provide information on the functional status of tissue; and using exogenous contrast material
to extract information regarding the spatial distribution, tissue function, metabolic activity, and to monitor expression.
To help make the structures in the knee easier to see, the MR technologist may inject a contrast material

In any event, reports on such samples should contain the caveat that radio contrast material
had been administered before sample collection and that any unexpected results should be confirmed by recollection and repeat analysis or consultation with a senior member of the laboratory staff.
Our in vitro experiments would suggest that injection of 60-80 mL (assuming the circulatory volume of an adult to be 3-4 L) of the nonionic contrast material
might be sufficient to cause interference with gel barrier formation.

When a contrast material
called gadolinium is injected just before an MRI, active areas of "silent" MS activity can be detected.
Because PPSQ is a relatively low contrast material
, they replaced it with a higher contrast poly (methylmethacrylate) resist material in order to make the 12-nm features.
Other indications included a history of a previous reaction to a contrast material
(21 percent of the responses), unstable angina (19 percent), and elevated BUN or Creatinine (9 percent).
