Diffusion tensor magnetic resonance imaging is being used on hearts to determine abnormal heart rhythms. This new cutting-edge technique takes detailed images of the structure of the heart muscle to check for “muscle fibre disarray” compared to the traditional way through family history and calculating the thickness of their wall including any unexplained collapses and abnormal heart rhythms.
Researchers at Oxford University conducted the study involving 50 patients with hypertropic cardiomyopathy and 30 healthy subjects. The study concluded a ‘disarray’ found in living heart patients which was the same as in patients after sudden cardiac death.
