Our view of the service

We inspected Trinity Medical Imaging using our comprehensive inspection methodology and carried out the unannounced inspection on 17 March 2026. This assessment was carried out because of the service’s aged rating.

TMI received the majority of its referrals from NHS providers in the UK. Most patients were seen through the routine NHS pathway, with a smaller proportion of privately funded, urgent NHS, and cancer pathway referrals.

The provider had a total of 2 sites, TMI house specialising in nuclear medicine scanning, including SPECT, DAT scans and MUGA scans.The new sister site that we did not inspect, but were told had taken over the performance of ultrasound scanning. We inspected the main site, based in TMI house. This focused on the treatment of adult patients but the service also accepted paediatric patients, over 5 years of age. Between January 2025 to December 2025, the service provided diagnostic imaging for a total of 4158 patients. This was divided into the following age categories. For patients under 18 years of age, 108 patients were scanned. For adult patients between 18 and 70 years, 2978 patients were scanned. For patients over 70 years, there were 1072 patient scans performed. From January 2025 to December 2025 the majority of TMI’s patients were aged between 61-70 years old.

Across all age ranges TMI carried out a total of 3254 Nuclear medical scans, 2 Dexa scans and 902 ultrasound scans. We were unable to assess the ultrasound facilities during this assessment, as ultrasound scanning facilities were no longer at this site.

However, we were told within the ‘last few months’ that ultrasound scans had been taken over by their sister site.

We rated the service as Requires Improvement. We found 1 breach of the regulation in relation to governance. Governance systems and audits were not effective in identifying or addressing areas of risk.

However, staff were caring and treated patients with compassion, kindness, dignity and respect.

We have requested an action plan, this will be requested upon publication of the final report.

People's experience of this service

Throughout the inspection, we took account of what people told us and how the provider understood and complied with the Mental Capacity Act 2005. We reviewed patient survey data collected by the service via online and paper reviews. Most patients accessed the service via NHS referrals. Patient experiences were positive in nature. For example, when asked whether they would recommend the service all patients said they were either extremely likely or likely to recommend the service to family and friends. They rated the overall quality of the service as excellent or good and would overall rate their visit as excellent or very good.

There were no complaints reported within the last 12 months.

During our assessment visit we observed staff to be respectful, kind and caring in their interactions with patients and patient’s relatives and carers. Whether this was face-to-face with patients (and their relatives) or involved in phone contact.

All the patients and relatives that we spoke to during our assessment visit gave us positive comments about their experience of the service, be that the time taken for the appointment, the receptiveness shown by staff when explaining procedures and the staff responses to their questions.
