PROPELLER WITH DIXON WATER FAT SEPARATION

摘要

The invention relates to a magnetic resonance imaging system (100) for acquiring at least one set of k-space blade data from an imaging zone of a subject (118), wherein the magnetic resonance imaging system (100) comprises a memory (138) for storing machine executable instructions and a processor (130) for controlling the magnetic resonance imaging system (100), wherein execution of the machine executable instructions causes the processor (130) to perform for each blade of the at least one set of k-space blade data: control the MRI system (100) to acquire at least one k-space blade data using at least one echo time for purposes of performing a Dixon technique, wherein k-space blade data are acquired in accordance with a blade shape; reconstruct at least one blade image data using the at least one k-space blade data; generate water blade image data and fat blade image data using the at least one blade image data; and transform the water and fat blade image data to water and fat k-space blade data respectively and perform PROPELLER reconstruction of the water and fat k-space blade data.
