No, of course. What a strange thing to say.

Progress yes, but nothing you could fit to a straight log plot.

There's active and passive, functional and structural, destructive and
nondestructive, resolution temporal and spatial. Destructive has the
highest potential for spatial, down to submolecular resolution. MRI
microscopy stops at a few cubic microns, on tiny specimens, fMRI doesn't
see anything much faster than few 10 s, PET blah, MEG can handle time
but not space. Do a websearch.
1) What exactly do you want to know?
2) Why do you want to know?
