Abstract
Disclosed is a system and method for determining a severity of a stenosis in a blood vessel depicted in a magnetic resonance imaging (MRI) data set. The system comprises a neural network configured to calculate the severity of the stenosis in the blood vessel based upon a number of input parameters, and the input parameters including at least one characteristic of a signal void associated with the stenosis in the MRI data set. The input parameters may include, for example, a flow rate of blood through the blood vessel, a length of a longitudinal axis of the signal void, and an average image intensity along the longitudinal axis of the signal void as well as other input parameters.
