A screening produces a document, and a document is only worth what the next doctor can do with it. This page is about the mechanics of getting it into your own doctor's hands in a usable state, which is mostly a matter of two requests made while you are still in the building.
No figure appears on this page, so nothing here is sourced or unsourced. It describes a process. The separate question of whether a doctor at home is obliged to act on findings from a clinic they do not know is answered on the reports page, which states the limitation rather than talking around it, and this page assumes you have read that and want to know what to actually do.
The images, not pictures of the images. A radiologist at home needs the original imaging data on media they can open, not a PDF of selected views. Ask what you are leaving with and confirm you can read it before you fly, because this is trivially fixed at the desk and genuinely awkward from another continent.
A named reporter and a stated standard. A report signed by the reading physician, with their licence number and the reporting standard used, is a document another clinician can situate. An unsigned summary is not, whatever it says. This is the single most useful thing to check before you leave.
A short conversation before the trip is worth more than anything that happens after it. Your GP knows your history and can name what would actually be useful to bring back, which is better targeted than a general screening package or anything a booking service can infer. It also means the report lands as a document they were expecting rather than as an unexplained file from abroad, and that difference is most of how these records get read or ignored.
If there is one thing on this page to act on before booking rather than after, it is this.
You do not wait in Korea for the written report. There is a consultation on the day covering preliminary findings, and the full document follows by email or post after you have flown, which means a longer turnaround does not lengthen the trip. How long that is, and the fact that one of the centres publishes no turnaround figure at all, is set out separately rather than summarised into a single reassuring number here.
