CT waiting times in Cardiff
Waiting times for CT scans at Cardiff and Vale University Health Board, which serves Cardiff, Wales.
These are Wales figures, not NHS England data. Health services in Wales are run separately and publish their own statistics, which use different definitions. Figures here come from StatsWales and the Welsh Government NHS activity and performance summary.
A CT (computed tomography) scan uses X-rays and a computer to make cross-section images of the body. It is quick and widely used for the chest, abdomen, head and to stage cancer.
At the end of the month (August 2026), 2,888 people were waiting for a CT scan at Cardiff and Vale University Health Board, of whom 1,206 (41.8%) had waited more than 8 weeks. Across Wales the figure was 21.7%; a lower percentage is better. Welsh diagnostic figures use an 8-week measure (people waiting more than 8 weeks), not the 6-week measure used in England and Scotland, so the numbers are not directly comparable.

Frequently asked questions
How long is the wait for a CT scan in Cardiff?
41.8% of the 2,888 people waiting at Cardiff and Vale University Health Board had waited more than 8 weeks (August 2026), compared with 21.7% across Wales.
Why is this not the same measure as England?
Welsh diagnostic figures use an 8-week measure (people waiting more than 8 weeks), not the 6-week measure used in England and Scotland, so the numbers are not directly comparable. England reports the share waiting under 6 weeks from NHS England’s DM01 return.
