It's a cool explanation, but I'm not sure what a CT scan offers that cutting it in half with a bandsaw wouldn't.
That said, it's a kind of marketing I like, since it does have some underlying product-performance and educational virtue to it.
Why of all common things you could CT scan and show people, you choose something that is kinda obvious to anyone who has thought about it for five seconds? I don't think average people struggle to understand the concept of "electricity makes wire hot", especially if they lived at the same time as normal car cigarette lighter usage.
They have a scan of a dang football, and it isn't because people don't know there's air inside: https://www.lumafield.com/article/ct-big-game-football
Learn with a simple toy example before moving onto the industrial-grade deconstruction that really shows the power of the tool. These guys have done CT scans of things like real vs. fake airPods and charger bricks to show what really justifies their (probably) 7 or 8-figure price tags.
This one is just content marketing of something anyone can wrap their head around.
It's a shame cars don't come with them anymore. A lighter can save someone's life and cost next to nothing. You can toss a lighter in but something about the designated electric plug is pleasing and invites you not to lose it.
