WB - DW MRI or Ga68 PSMA PET/CT ?

[traveller64]

Does anyone have experience with whole body diffusion weighted MRI to detect mets after PSA recurrence. A MO told me that WB - DW MRI is superior to Ga68 PSMA PET/CT.

Here is a study comparing the two:

That was a downer, wasn't it? Here I was hoping for something better and less intrusive than the existing standard test.

And for anyone who didn't check the link posted by GP24, it said that the Ga68 PSMA PET/CT test was better than the WB-DW MRI.

I personally prefer the PSMA PET/MRI over the PSMA PET/CT. But an MRI without PSMA tracer is not as sensitive as a PSMA PET.

This study compares whole body MRI with Ga68 PSMA PET/CT. Isn't there a difference between whole body MRI and Diffusion Weighted Whole Body MRI?

Traveller64- As you probably know, a USPIO MRI is superior to a PET/CT for detecting cancerous lymph nodes, at least at Radboud University.

Allen, actually I'm looking for information regarding the WB - DW MRI to detect mets in the whole body, not specifically the lymph nodes. I guess they use USPIO enhanced DW MRI to detect mets in pelvic lymph nodes
