1. A computer implemented method for assessing an arterio-venous malformation (AVM), the method comprising:
receiving image data of at least a portion of a vascular system of a patient, including one or more blood vessels associated with the AVM;
generating a patient-specific three-dimensional anatomic model of the portion of the vascular system of the patient, using the received image data;
identifying, using a computer processor, one or more larger blood vessels among the one or more blood vessels associated with the AVM; and
generating a treatment recommendation for treating the AVM, based on the identified one or more larger blood vessels, wherein generating the treatment recommendation includes predicting an increase or decrease in (a) a radius of the AVM or (b) a radius of the one or more blood vessels associated with the AVM.
