METHOD AND MAGNETIC RESONANCE APPARATUS FOR AUTOMATIC ASSIGNMENT OF A SPIN SPECIES TO A COMBINATION IMAGE

摘要

In a method and apparatus for the automatic assignment of at least one combination image of an examination object to a spin species represented in the combination image, relationships, which were determined from an existing database and which relate to the assignment of spin species to combination images, are loaded into a computer. At least two MR datasets at one of at least two echo times in each case following an excitation by means of a multi-contrast measurement are supplied to the computer. At least one combination image is determined in the computer from the at least two MR datasets. The spin species represented in the at least one combination image are assigned in the computer on the basis of the loaded relationships. By using relationships determined from an existing database, an automatic unambiguous global assignment of the correct spin species is enabled.

1. A method for automatic assignment of at least one magnetic resonance combination image of an examination subject to a magnetic resonance spin species represented in the combination image, comprising:
loading predetermined relationships, determined from existing databases, into a computer that define assignment of magnetic resonance spin species to magnetic resonance combination images; operating a magnetic resonance data acquisition scanner to execute a multi-contrast magnetic resonance data acquisition measurement in which at least two echo times are produced, and acquiring at least two magnetic resonance datasets respectively during said at least two echo times; providing said magnetic resonance datasets to said computer and reconstructing at least one combination image from said at least two magnetic resonance datasets; in said computer, using the loaded relationships to assign spin species represented in said determined at least one combination image to respective magnetic resonance spin species; and making an electronic signal representing the assignment of the respective magnetic resonance spin species available from the computer in electronic form.
