Commonalities & Differences between these Scans for Knee Joint?

  • MRI Scan Knee Joint
  • MRI Scan Knee Arthrography
  • MRI Scan Knee Joint Contrast (Fasting Reqd)
  • MRI Scan Knee with Cartilage Mapping

(This is as listed in Radio Imaging Lab's options and similar but different words are being used online from whatever I read. More confused and less clear).

Direction on inquiry:

  • Are some of them Super Sets of other on the list?
  • What can each of them help show/ uncover from the knee structures & tissues and/or not?
  • When would one be preferred over another and when might one escalate to the "greater/ finer" one of them?

Maybe someone can share some highlights

Link me to a good comparative article or study that can shed light on the above?

PS: My googling has not been able to give much clarity on the above


UPDATE:

More reading and more confusion between these terms and wondering which are same or different.

  • Arthrography | Arthrogram | Arthro-Scopy | Angiography |

Some articles mention MR with Athrogram as with Contrast dye injection

  • Could you please clarify where these things come from and why you're asking? It's all rather abrupt and without background.

  • I said so already. It’s from a radio lab list and I’m trying understand how they work. Curious how far the tech is able to map different structures.

  • @CareyGregory - Added some links from going through around 40 or 50 links. Google doesnt help clarify.
