Here’s how this new technology diagnoses heart failure in 8 minutes



A unique technology has been developed to diagnose patients with heart failure half-time than usual, which can also be helpful in providing more effective treatment to patients. Researchers at the University of East Anglia (UEA), UK, developed the innovative technology, according to news agency PTI.

These researchers are using magnetic resonance imaging (MRI) to develop detailed four-dimensional (4D) flow images of the heart using a super-fast method called “Kat-ARC” that takes just eight minutes, unlike to conventional MRI which takes up to 20 minutes or more.

These 4D flow images provide an accurate picture of heart valves and blood flow inside the heart, which will help doctors determine the best treatment for patients.

UEA’s Pankaj Garg, a lead researcher, said heart failure is a terrible condition resulting from increased pressures inside the heart, according to PTI reports.

“The whole team researched one of the most advanced methods of assessing flow inside the heart called 4D flow MRI. In this we can look at the flow in three directions over time – the fourth dimension,” said Pankaj Garg. .

The best method for diagnosing heart failure is invasive evaluation which is not preferred because it carries risks, according to research published in the journal European Radiology Experimental.

Scientists said that an ultrasound of the heart called echocardiography is usually used to measure the maximum speed of blood flow through the mitral valve of the heart, however, this method may not be reliable.

Hosamadin Assadi, a Ph.D. UEA student said, “This new technology is revolutionizing the way heart disease patients are diagnosed. However, it takes up to 20 minutes to perform a 4D flow MRI and we know that patients don’t like having long MRIs.

Following this, the research team further investigated the reliability of a new technique that uses ultra-fast methods to analyze flux in the core, called Kat-ARC.

The Ph.D. student said it cuts scanning time in half and takes about eight minutes to diagnose heart failure and measure peak blood flow velocity in the heart accurately and precisely.

The team tested the new technology with 50 patients at two hospitals in Sheffield, UK. Patients with suspected heart failure were assessed using the new Kat-ARC 4D Cardiac Flow MRI.
