Scientists have built cutting-edge imaging technology to
assist doctors in better diagnosing and monitoring heart failure patients. The
cutting-edge method creates comprehensive 4D flow images of the heart using
magnetic resonance imaging (MRI). The 4D heart MRI scan takes about six to
eight minutes and can offer exact three-dimensional imaging of the heart valves
and flow inside the heart, assisting doctors in finding the best treatment
options for patients.
Researchers at the University of East Anglia (Norwich,
Norfolk, UK) have demonstrated how this non-invasive imaging approach can
correctly and precisely detect the peak velocity of blood flow in the heart.
The new technology was tested on 50 patients with suspected heart failure who
were evaluated using both echocardiography and the new and advanced 4D flow
heart MRI. The researchers created a software prototype to automate the process
of monitoring the peak velocity of blood flow inside the heart. The researchers
believe that their findings will change the way heart failure is diagnosed.
"We used one of the most cutting-edge methods of flow
evaluation inside the heart termed 4D flow MRI in our study," stated lead
researcher Dr. Pankaj Garg of the University of East Anglia's Norwich Medical
School. "We can look at the flow in three directions throughout
time with 4D flow MRI." We used automated ways to hunt for the peak
velocity in the heart chamber and shown that it is similar to echocardiography
assessment, but with considerably more precision."
"This work is crucial because the inability of the
heart to relax causes an increase in pressures inside the heart, which causes
cardiac failure with adequate ejection fraction," Dr. Garg stated.
"Peak velocity of blood flow inside the heart is a very important
parameter for patients, and our findings show that we can obtain this reliably
and with a high degree of accuracy." degree of repeatability by employing state-of-the-art
4D flow MRI imaging." This advanced imaging approach is an alternative to
ultrasound and may even be superior to ultrasound in the future."
