1. A method for acquiring magnetic resonance data from a subject comprising:
- from a computer, operating a magnetic resonance data acquisition scanner to execute a first diagnostic imaging scan, comprising acquiring a first set of magnetic resonance scan data from a first sub-region of an examination region of a subject situated in the scanner;
from said computer, operating the magnetic resonance data acquisition scanner to execute a second diagnostic imaging scan, comprising acquiring a second set of magnetic resonance scan data from a sub-region of the examination region of the subject situated in the scanner;
from said computer, operating the magnetic resonance data acquisition scanner to execute a navigator scan chronologically between said first diagnostic imaging scan and said second diagnostic imaging scan, said navigator scan comprising acquiring navigator data from at least two navigator slices situated on opposite sides of said examination region of the subject situated in the scanner; and
from said computer, making the first and second sets of magnetic resonance scan data, and the navigator data, available from said computer in electronic form, as at least one data file.

Abstract
In a method and apparatus for magnetic resonance imaging, a first diagnostic imaging scan is executed that includes a recording of first set of magnetic resonance scan data from a first subregion of an examination region, and a second diagnostic imaging scan is executed that includes a recording of a second set of magnetic resonance scan data from a second subregion of the examination region. A navigator scan is executed chronologically between the first diagnostic imaging scan and second diagnostic imaging scan, wherein the navigator scan includes a recording of at least two navigator slices arranged on opposite sides of the examination region.
