3D heart scans have saved NHS millions since 2021 rollout, data shows
The technology cuts the needs for invasive tests and speeds up diagnosis by turning a CT scan into a three-dimensional image to be analysed by artificial intelligence (AI).
More than 24,300 patients have received the scan and data shows this has allowed hundreds to avoid invasive procedures and saved the NHS the equivalent of about £390 per patient, NHS England said.
Coronary heart disease sufferer Sarah Remnant, from Portsmouth, said her case was not a 'classic' one but was quickly spotted thanks to the technology.
Days after the 3D scan Ms Remnant, then aged 50, had surgery to fit a potentially life-saving stent.
Now recovered, she said: 'I wasn't a classic case but thanks to this technology, the cause of my symptoms was quickly identified – which possibly saved my life.
'The consultant talked me through the scan, which was empowering as I could fully understand my diagnosis and the plan for treatment.
'I feel amazing now and am very grateful that I had access to this as it was so reassuring to have that extra information at such a worrying time.'
Previously, patients suspected of having coronary heart disease received a CT scan if a 'narrowing or blockage' in a coronary artery was suspected, NHS England said.
To confirm a diagnosis many would then need an invasive angiogram.
This involves clinicians inserting a catheter into a blood vessel and injecting dye to make blocked blood vessels show up on an X-ray.
A study funded by Medical Research Council looked at more than 90,000 NHS patients between 2017 and 2020 and the tool was used on nearly 8,000 of them.
The 3D scans reduced the number of patients needing an invasive angiogram test by 7%.
This was cut by a sixth, or 16%, among those later found to require no further treatment, it said.
As a result of the 3D scan, now available in 56 hospitals in England, an invasive angiogram is only recommended if the patient may need surgery or a stent.
The tool can also suggest the size and position of stent most suitable for the patient.
Dr Vin Diwakar, national director of transformation at NHS England, said: 'It is fantastic see that these revolutionary AI-driven 3D heart scans, supported by NHS England, are transforming cardiac care by significantly reducing the need for invasive tests, speeding up diagnoses, conserving NHS resources, and enabling clinicians to advise patients on the best treatment for their condition.'
The AI-driven analysis is called Heartflow and more than 6,989 people have had access to it in the last year, NHS England said.
Coronary heart disease affects around 2.3 million people in England and is the most common type of heart disease.
It develops when fatty material builds up inside the coronary arteries, which can restrict blood flow and oxygen supply to the heart.
Patients are at risk of heart attacks or heart failure.
NHS England rolled out the technology through the MedTech Funding Mandate programme, which aims to ensure patients and the NHS receive clinically effective and cost-saving medical technologies faster and fairer.
It said: 'The sci-fi-like tool is helping give tens of thousands of patients at risk of potentially life-threatening coronary heart disease a faster and more accurate diagnosis, while also freeing up capacity in the NHS.'

The remote UK island looking for a new nurse
NHS Shetland is seeking a new nurse for Fair Isle, the UK 's most remote inhabited island, as the current nurse is due to leave later this month. The successful candidate will be the sole medical professional for the island's approximately 50 residents, providing comprehensive care from newborns to the elderly. The role demands a high degree of personal resilience due to the island's isolation, weather-dependent transport, and the need to provide care without local social care provision. The full-time position offers a salary range of £41,608 to £50,702, a distant island allowance, and relocation assistance, with a two-bedroom house available to rent. Fair Isle residents have expressed concern about the vacancy, emphasising the unique challenge and rewarding opportunity for an experienced and confident clinician.

HIV testing in Leeds hospitals can lead to life-saving treatment
More than 35,000 patients have been tested for HIV and hepatitis B and C in the first eight months of a new scheme running in hospitals across Teaching Hospitals NHS Trust said the tests had led to 11 new cases of HIV being diagnosed, in addition to 101 new - or active - cases of hepatitis B or C."This is such a good opportunity to be able to diagnose those individuals who have these infections and don't realise they do, because we can offer them life-saving treatment," said Dr Emma Page, consultant in virology at Leeds Teaching Hospitals NHS Trust."We're all at risk of blood-borne viruses, and the only way we can know whether we have them or not, is by having a test," she said. "Offering routine HIV and hepatitis tests in our Emergency Departments can make a huge difference to patients," said Dr Page."It can save lives and give people access to the latest, and most effective, treatments."Dr Page said there are often few indications that a person has HIV or hepatatis B or C initially. "We'll often feel very well with them until we've had the infection for many years," she she highlighted the importance of treatment."There are tablets that people can take to control the infection and prevent them from getting unwell, or tablets that can actually cure some of these infections. "So we're really excited that these tests are happening in our Emergency Departments at the moment," she added. Dr Sarah Schoeman, genitourinary medicine consultant at the trust, said: "If people are identified as having HIV or hepatitis, there is a very clear, and safe, and quick pathway for you to be referred - either into the HIV service or hepatitis services - to access care, treatment, support, advice."This will ensure that you have all the information you need, to be able to keep yourself healthy going forward, and also eliminate any chance of you passing on any infection to partners as well. "Knowing your status means that you have all the options available to you to be able to access excellent treatment, and a lot of support as well."

GPs using fewer physician associates, survey suggests
A new survey, conducted by the GP magazine Pulse, found that 21% of 425 GP networks in England said they had reduced PA numbers in the last year. It comes after the Government-ordered Leng Review found PAs have been used as substitutes for doctors, despite having significantly less training. One of the 18 recommendations in the review was that PAs be banned from seeing patients whom a medic has not reviewed to prevent the risk of 'catastrophic' misdiagnoses. Pulse said that the main reasons GPs gave for cutting back on PAs included: guidance from professional bodies; supervision demands; patient safety concerns and rising complaints. One GP told Pulse: 'We had a PA but now don't use them because of the change in guidance. 'We can't afford to pay someone with such limited scope.' On Friday, the union representing PAs and anaesthesia associates (AAs), United Medical Associate Professionals (UMAPs), lost a High Court bid to temporarily block NHS England from implementing recommended changes from the Leng Review. More than 3,500 PAs and 100 AAs are working in the NHS, and there have been previous calls for an expansion in their number. But their roles were reviewed following high-profile deaths of patients who were misdiagnosed by PAs, with six patient deaths linked to PAs recorded by coroners in England. The Leng Review gives a thorough assessment of the safety and effectiveness of physician and anaesthesia associates in the NHS. We welcome the independent review into these roles, which exist to support medical teams and not as substitutes for doctors or anaesthetists. — NHS England (@NHSEngland) July 16, 2025 They include 30-year-old Emily Chesterton, who died from a pulmonary embolism after being misdiagnosed by a PA on two occasions and told she had anxiety. In her report, Professor Gillian Leng concluded there were 'no convincing reasons to abolish the roles of AA or PA' but there was also no case 'for continuing with the roles unchanged'. She said more detail was needed on which patients could be seen by PAs, and national clinical protocols will now be developed in this area. Commenting on the Pulse survey, UMAP general secretary Stephen Nash said: 'Physician associates are highly trained medical professionals who play a vital role in improving patients' access to primary care, particularly in underserved parts of the health service.' He added: 'According to this survey the vast majority of primary care networks are retaining their PA staff. 'This is a testament to PAs' hard work and expertise.'
