What's inside Apple's $129 Thunderbolt cable? We CT scanned one to find out

The company the Twitter user works for, Lumafield, makes CT scanners for industrial uses similar to this, so they have a couple lying around the office. They're definitely not paying retail US healthcare prices. Likely the cost to them based on human time spent far exceeds what you'd pay for a tech at a hospital, but it's good advertising.

It's an advertising thing. They do these regularly with new stuff.

Not as cool nerd

A CT scan for calcium scoring is around $100 in the US- and that includes radiologist time to interpret the scan. That is not a negotiated price either- insurance does not cover such scans.

Having said that, no healthcare imaging facility would agree to scan a random cable that someone brought in off the street- unless you knew someone. And then it would probably be free because the marginal cost of running a scan is very low with no radiologist time.
