IgM, Muggis, or Waldenstrom's?

For most patients, actually imaging for me is kind of optional. I think it's uncommon for symptomatic Waldenstroms that much is gained from the PET scan. You see the adenopathy, you see the uptake, but it usually doesn't drive a decision to treat patients. CBC chemistry, viscosity, when it's over 4000 and the bone marrow. Those are the really big things that you really need to know.
