A question for OCADers:
Who is doing 3D isotropic imaging of joints on a regular basis?
How long is the acquisition on average?
Are you using GE or Siemens (or other)?
1.5T/3T?
What are the major image quality issues?
We are investigating 3T scanners and are interested in integrating these sequences but want to know how others are using them.
BTW here is another valuable hardware web site: medapparatus.com/
Thank you!

If you are talking of GRE or DESS type- they are around for 2 decades or more
For spin echo TSW-
At JHU – since 2009
At UTSW- since 2013
All joints
Go for Siemens
5-6 min with capri space
3-4 min with compressed sense
isotropic beautiful images
Our orthopods are used to it- they demand it
You can now measure meniscal and labral tears

We also routinely do 3D for MR neurography and spondyloarthropathy, etc.
Best!
