Cardiac magnetic resonance imaging (MRI) analysis can be performed significantly faster with precision similar to experts when using artificial intelligence also Known as AI in the form of automated machine learning, according to a new study.

Currently, analysing heart function on cardiac MRI scans takes approximately 13 minutes for humans.

Utilising AI, a scan can be analyzed with comparable precision in approximately four seconds, according to the findings published in the journal Cardiovascular Imaging.

“Our dataset of patients with a range of heart diseases who received scans enabled us to demonstrate that the greatest sources of measurement error arise from human factors.

“This indicates that automated techniques are at least as good as humans, with the potential soon to be ‘super-human’–transforming clinical and research measurement precision,” said study author Charlotte Manisty from the University College London.

In the UK, where the study was conducted, it is estimated that more than 150,000 cardiac MRI scans are performed each year.

Based on the number of scans per year, researchers believe that utilising AI to read scans could potentially lead to saving 54 clinician days per year at each UK health centre.

Researchers trained a neural network to read the cardiac MRI scans and the results of almost 600 patients.

However, when the AI was tested for precision compared to an expert and trainee on 110 separate patients from multiple centres, researchers found that there was no significant difference in accuracy.

Start Checking Your Cholestrol Level from Mid-20s to Avoid Heart Disease: Study

Cholesterol is a fatty substance - a lipid - found in some foods and also produced in our liver

Researchers analysed the data obtained from almost four lakh persons in 19 countries and found a strong link between bad-cholesterol levels and risk of Heart disease from early adulthood over the next 40 years or more. Pixabay

A study has said that people should get their cholesterol levels checked from their mid-20s as the readings can be used to calculate lifetime risks of Heart disease and stroke.

The study, published in “The Lancet”, is the most comprehensive yet to look at the long-term health risks of having too much “bad” cholesterol for decades, the BBC reported.

Researchers maintain that earlier the people take action to reduce cholesterol through diet changes and medication, the better.

Cholesterol is a fatty substance – a lipid – found in some foods and also produced in our liver. It is needed to make hormones like oestrogen and testosterone, Vitamin D and other compounds.

While High-density lipoprotein (HDL) cholesterol is “good” as it keeps the body healthy, Low-density lipoprotein (LDL) is “bad” as it can clog arteries.

Researchers analysed the data obtained from almost four lakh persons in 19 countries and found a strong link between bad-cholesterol levels and risk of cardiovascular disease from early adulthood over the next 40 years or more.

They were able to estimate the probability of a heart attack or stroke for people aged 35 and over, according to their gender, bad-cholesterol level, age and risk factors such as smoking, diabetes, height and weight, and blood pressure.

The BBC quoted the report’s co-author Stefan Blankenberg of the University Heart Center in Hamburg: “The risk scores currently used in the clinic to decide whether a person should have lipid-lowering treatment only assess the risk of cardiovascular disease over 10 years and so may underestimate lifetime risk, particularly in young people.”

Blankenberg told BBC: “I strongly recommend that young people know their cholesterol levels and make an informed decision about the result – and that could include taking a statin.”

However, he added, there is a danger that people could rely on statins rather than leading a health lifestyle and although they were usually well tolerated, studies had not been done on the potential side-effects of taking them over decades.

British Heart Foundation medical director Nilesh Samani said: “This large study again emphasises the importance of cholesterol as a major risk factor for heart attacks and strokes.

“It also shows that for some people, taking measures at a much earlier stage to lower cholesterol, for example by taking statins, may have a substantial benefit in reducing their lifelong risk from these diseases.” (IANS)
