MRI method for simultaneous phase contrast angiography and invasive device tracking

摘要

A method for simultaneously tracking an invasive device disposed within a patient and acquiring an imaging signal of the patient with a magnetic resonance imaging (MRI) system during a single echo acquisition time period ( 46 ) of the MRI system. The method includes applying a radio frequency excitation pulse ( 26 ) to a patient to start an echo acquisition time period of an MRI system. The method then includes acquiring a tracking signal ( 54 ) from the invasive device during the echo acquisition time period and also acquiring an imaging signal ( 36 ) of the patient proximate an end of the same echo acquisition time period.
