"why not skip to that?" MRIs and CT scans are expensive, require referrals, and you usually can't get them without believing you already have an issue. If this technology can get to a point where it's high enough resolution, cheap enough to just have at spas, and shared across the world then people will be able to know if/when they should get that secondary scan before symptoms start.

Probably cheaper and substantially better contrast resolution to use low field strength perma magnet MRIs with advanced computation to be honest.
