Virtual angiogram systems and methods for assessment of aneurysms

A method comprising:

• performing a virtual angiogram by simulating transport of contrast agent through a model of a portion of a vasculature of a patient based on a patient-specific pulsatile flow velocity field of said vasculature portion, the vasculature portion including a plurality of aneurysms, at least one of the aneurysms being ruptured;
• determining at least one contrast retention metric for each of the plurality of aneurysms based on the virtual angiogram, each contrast retention metric being indicative of flow stagnation in the respective aneurysm;
• identifying at least one of the plurality of aneurysms as ruptured based at least in part on the contrast retention metrics;
• and
• physically administering an endovascular, surgical, or radiosurgical treatment to stabilize, occlude, or obliterate the at least one aneurysm identified as ruptured.

An aneurysm assessment system comprising:

• one or more processors;
• and
• one or more non-transitory media storing computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to:
• perform a virtual angiogram by simulating transport of contrast agent through a model of a portion of a vasculature of a patient based on a patient-specific pulsatile flow velocity field of said vasculature portion, the vasculature portion including at least one aneurysm;
• determine at least one contrast retention metric for the at least one aneurysm based on the virtual angiogram, the at least one contrast retention metric being indicative of flow stagnation in the respective aneurysm;
• and
• identify the at least one aneurysm as stable, unstable, or ruptured based at least in part on the at least one contrast retention metric.
