Better tumour imaging using nanodiamond-based dual-mode contrast agent
Metal-based contrast agents
cost more than sugar-based agents.
Further, since this new MRI contrast agent
will substantially improve disease detection by increasing sensitivity and diagnostic confidence, it will enable earlier treatment for many diseases, which is less expensive, and of course more effective for diseases such as cancer," he added.
EXAMPLES AND INDICATIONS OF CURRENTLY AVAILABLE CONTRAST AGENTS
Increased blood supply to the bowel wall can't be distinguished from a positive contrast agent
, as both appear white on a scan.
The FDA has not yet determined whether exposure by patients with kidney failure to gadolinium-containing contrast agents
during an MRA test causes NSF.
Some contrast agents
carry a small risk of allergic reaction, so it is important to tell the radiologic technologist who will perform your examination if you have any type of allergy.
Through March 1989, there have been a number of articles on the subject, but the indications for the use of the new contrast agents
are very ill-defined.
Main said that although the FDA retained boxed warnings on both ultrasound contrast agents
, newer safety data demonstrate a more favorable risk-benefit profile that ultimately may warrant additional label changes with removal of the boxed warnings.
Paramagnetic, macrocyclic gadolinium contrast agent
at a concentration 1,0mmol / ml in packs:
Buckyballs may be especially useful for shuttling metal contrast agents
through the body for magnetic resonance imaging (MRI) scans, Bolskar says.
Main said that although the FDA's current boxed warnings for ultrasound contrast agents
are not warranted by safety data, the label modification for DEFINITY[R] "makes important incremental progress based on sound science that now more accurately reflects the risk benefit profile.
