1. A method for planning treatment for arterial stenotic lesions, comprising: identifying a set of stenotic lesions in a patient's coronary arteries from medical image data of the patient; generating a plurality of treatment options for the set of stenotic lesions, wherein each of the plurality of treatment options corresponds to a stenting configuration in which one or more of the stenotic lesions are stented; and calculating, for each of the plurality of treatment options, predicted hemodynamic metrics for the set of stenotic lesions resulting from the stenting configuration corresponding to that treatment option.
