A magnetic resonance imaging (MRI) system semi-automatically performs non-contrast magnetic resonance angiography (MRA). An operator display and control input port configures the MRI system to effect semi-automated non-contrast MRA imaging with spatially selective tag and venous suppression RF pulses and/or black blood time interval (BBTI) parameters in a non-contrast MRA data acquisition sequence where such parameters are automatically determined within predetermined, respectively corresponding, spatial regions of patient anatomy. Such automatically determined non-contrast MRA imaging parameters may be entirely automatically set and used or, alternatively, may be displayed to an operator for acceptance and/or change before being used.
