Patients will be able to have scans and tests at a new Community Diagnostic Centre (CDC) from this month.
North Bristol NHS Trust (NBT) will be offering appointments at the new facility, by Asda at Cribbs Causeway, in mobile units until a permanent building is completed.
The CDC, part of the drive to cut waiting lists, will enable NBT to provide 45,000 diagnostic procedures every year, in partnership with independent healthcare provider InHealth.
The diagnostics offered will include Endoscopy, Respiratory, Echo and Imaging (X-ray, MRI and CT scans).
The Government has agreed to invest £2.3billion in opening about 160 CDCs across the country by next year, providing nine million additional tests per year for patients in England.
