here it says that "Diffusion-weighted imaging contrast (specialized T2* weighting)."

but given that DWI is based on a spin echo (vs. gradient echo) EPI, I would call it a "specialized T2 weighting" instead.

Pinging @oesteban, who might be able to weigh in on this.

If it is something that needs to be changed, we can do that in the suffixes schema file:

dwi:
name: Diffusion-weighted image
description: |
Diffusion-weighted imaging contrast (specialized T2\* weighting).

@jcohenadad yes, just proposing a change to the file @tsalo is showing would be the way of updating the spec. You can do that on your browser by following this link -> https://github.com/bids-standard/bids-specification/edit/master/src/schema/objects/suffixes.yaml
