Abstract
In a magnetic resonance (MR) imaging method and apparatus, multiple diagnostic scans are obtained of an examination subject during an imaging session. An initial reference scan of the subject is obtained at the beginning of the session and, as the session proceeds, an automatic determination is made before each diagnostic scan is obtained as to whether the immediately preceding reference scan is still valid, primarily be checking whether an amount of patient movement has occurred that renders the immediately preceding reference scan invalid. Either a new reference scan is obtained before the next diagnostic scan, or, if still valid, the immediately preceding reference scan is used for the next diagnostic scan.
