A leading cardiologist based at Southampton’s teaching hospitals is the first in the world to develop a unique technique to “slice” 3D images of the heart into intricate sections using computer software. The advanced method, known as multiplane review (MPR) 3D echocardiography, allows the user to identify heart defects much more accurately than on traditional 2D or standard 3D scans and is revolutionising the accuracy and speed of diagnosis.
