Re: x-ray contrast media

     You should be able to identify the synovial space by standard 
     radiography, anterior, posterior or lateral shots.  Injecting 
     contrasting media into the synovial space might not produce the 
     results you are looking for.  In fact, it may flood the space and 
     obstruct the view.  There are standard contrast media used for 
     arthograms.. I don't know the name...sorry...Renographin 60 comes to 
     mind....Hope this helps..mike coogen

We use an yttrium-90 silicate colloid for radiation synovectomy, and it has 
been suggested that the initial placement of the needle in the joint space 
should, in some cases, be checked radiographically using a little contrast 
material.
However the colloid manufacturers advise that the colloid "should not be 
used in conjunction with x-ray opaque contrast injections as these normally 
contain EDTA or other chelating agents which may remove yttrium from the 
colloid media."  Can anyone please tell me if there are suitable contrast 
agents available which do not contain chelating agents?
