What running a PET-CT second-read service taught us about patient trust

In early 2023 a scan arrived from Lagos. A man whose father had been diagnosed with a neuroendocrine tumour had spent three weeks trying to find a nuclear medicine specialist willing to give a second opinion. He found the service through a search result. Dr. Sen reviewed the study the following morning; the signed report went out inside 48 hours.

Four things that changed after the first hundred cases

Frightened people do not read marketing. Every line of copy, every form field and every confirmation screen was rewritten for someone reading at 2am with a diagnosis they do not yet understand. No promotional language, no urgency mechanics.

Independence is the signal patients actually name. The service earns from interpretation and never from treatment. Asked why they chose it, patients cite that structure more often than turnaround, price, or the consultants' publication records.

Turnaround is a clinical commitment, not a service level. The 72-hour promise is backed by a 60-hour internal deadline. Each additional day of uncertainty has a measurable psychological cost for the family.

Upload is the hardest engineering problem, not the reporting. A 400MB DICOM study over an unstable connection from a user who has never seen a medical portal. Most of the build effort went there and it is invisible in every screenshot.
