Magnetic resonance method and system for flow measurement

A magnetic resonance system for magnetic resonance flow measurement, comprising:

• a magnetic resonance data acquisition unit;
• a control unit that operates said magnetic resonance data acquisition unit to obtain magnetic resonance angiography data from a volume within an examination subject;
• said control unit having an input supplied with said angiography measurement data and a user input and said control unit being configured to determine a vessel in said volume from said angiography measurement data, dependent on said user input;
• said control unit being configured to automatically determine dimensions and an orientation of said vessel from said angiography measurement data;
• said control unit being configured to automatically determine a slice for implementing a flow measurement therein dependent on said dimensions and said orientation of said vessel;
• and
• said control unit being configured to operate said magnetic resonance data acquisition unit to implement said flow measurement in said slice using said coding.

A computer-readable medium encoded with programming instructions, said medium being loadable into a computerized control system of a magnetic resonance system and said programming instructions causing said control system to:

• operate said magnetic resonance system to obtain magnetic resonance angiography data from a volume within an examination subject;
• receive said angiography measurement data and a user input, and to determine a vessel in said volume from said angiography measurement data, dependent on said user input;
• automatically determine dimensions and an orientation of said vessel from said angiography measurement data;
• automatically determine a slice for implementing a flow measurement therein dependent on said dimensions and said orientation of said vessel;
• and
• operate said magnetic resonance system to implement said flow measurement in said slice using said coding.
