Brand names

Last revised by Dr Henry Knipe on 14 Dec 2021

Brand names should generally not be used unless there is something specific about a particular brand that is important. An example of when a brand name is acceptable is an article or case that describes a specific implantable medical device with particular imaging features (see medical device article structure). 

For example, a particular programmable CSF shunt valve where the appearance of a normal valve and the interpretation of the pressure setting are brand-specific. 

If a case mentions a specific medical device by brand name then an author disclaimer is required at the very bottom of the case discussion. Please copy and paste the following: 

Disclosure: I, [insert your name], have no actual or potential ethical or financial conflict of interest in relation to this device. This case is not intended to be a personal endorsement or recommendation of this product.

Trademark symbols, such as "®" for registered trademarks and "™" for unregistered trademarks, are not required on Radiopaedia. This is in line with style guides such as The Chicago Manual of Style which state that there is no legal requirement to use such typographical devices 1.

For devices, etc. the manufacturer's name and country should be included after the first mention. For example, "The TightRope fixation system (Arthrex, Germany) is a reconstruction technique..."
