Posting this here because the Artifact folder seems to not have "child" folders, needed to take posts.

I noticed a bright-spot artifact on some hand images, of a type I had not noticed before (despite my alleged expertise in MRI Physics & methods since ~1982). My colleague (and Chief Tech) said he sees this routinely, in at the skin-air interface of CSpine as well as extremity images. The sequence type is T1=w 2DFT 5-echo-train FSE, with spectral-band-suppression for FatSat, on a Philips 3T Ingenia scanner. We don't see this on the non-FatSat series.
Attached example images have blue circle ROI overlays.

My question is: does this artifact have a common name?
