Wait times · United Kingdom

18 weeks is the NHS's own target.
Seoul does it in three days.

The NHS's own constitutional standard is 18 weeks from referral to treatment, and real waits routinely run longer, which is why Britain's self-pay diagnostics market has grown so fast. In Seoul the same imaging is scheduled in three days. The methodology line under the comparison table names every source this page draws on and the date each was read. Individual figures carry their own notes where there is more to say.

Wait for an MRI (NHS)

Share of MRI patients waiting six weeks or more, March 2026 (NHS England, Monthly Diagnostic Waiting Times and Activity, DM01). Accredited Official Statistics. NHS England publishes this share rather than a per-test median, and the operational standard is under 1%, which was not met.

Referral to treatment, median

Incomplete pathways, England, May 2026 (NHS England). The 18-week constitutional standard is a target rather than a measured wait; 65.6% were within it against an operational standard of 92%.

Full written report

Same-day consult on preliminary findings; the full report follows in two to three weeks depending on the centre. KMI publishes about two weeks; Hanaro publishes no figure at all (measured 2026-07-28). You are not in Korea waiting for it. Reports are sent by email (or by post, at one centre) once ready, after you have already flown home, so a longer report does not mean a longer trip.

NHS England, Monthly Diagnostic Waiting Times and Activity (DM01), March 2026 report, Table 2 and the March 2026 key findings. Accredited Official Statistics. MRI 21.6% and colonoscopy 28.8% of patients waiting six weeks or more, CT 10.0%, all tests 21.2%, and a median wait across all diagnostic tests of 2.9 weeks. The NHS operational standard is under 1% waiting six weeks or more and was not met. The referral-to-treatment figure is the measured median for incomplete pathways, 12.4 weeks, England only, May 2026 data, from NHS England's Referral to Treatment statistical press notice published 2026-07-09 (https://www.england.nhs.uk/statistics/wp-content/uploads/sites/2/2026/07/May26-RTT-statistical-press-notice-PDF-574K-3jBgba.pdf), read 2026-08-11. The same release gives a 92nd percentile of 38.6 weeks and 65.6% within 18 weeks against an operational standard of 92%. The 18-week figure this row carried until then was the NHS constitutional standard, a target rather than a wait anyone measured.
