Magnetic resonance imaging and risk factors for progression of lacunar infarct lesions in Chinese patients.

abstract：PURPOSE:Flow diverters (FD) have poor radiopacity, challenging visualization of deployment and vessel wall apposition with conventional neuroimaging modalities. We evaluated a novel cone beam computed tomography (CT) imaging technique that allows virtual dilution (VD) of contrast media to facilitate workflow and ensure...
