MRI Development Yields Breakthrough in Diagnosis of Liver Fibrosis

...d form of MRI to obtain pictures of the mechanical waves passing through the organ. The imaging can be accomplished in as little as 20 seconds. The wave pictures are then processed to generate a quantitative image of tissue stiffness -- called an elastogram. Researchers compared results of the process on...

A New System Developed For Studying The Condition Of The Human Arterial System
