The echo time in an MR pulse sequence is optimized in accordance with the application desired. Advantageously, the echo time is selected to cause a partial volume signal cancellation from veins as compared with background tissue, and the MR pulse sequence is of a velocity-compensated type. MR data are acquired from gradient echoes. Multiple echoes may be used to extract information (such as volume content and susceptibility) about the material under investigation.

Le temps d'écho dans M. ordre d'impulsion est optimisé selon l'application désirée. Avantageusement, l'heure d'écho est choisie de causer une annulation partielle de signal de volume des veines par rapport au tissu de fond, et M. ordre d'impulsion est d'un type vitesse-compensé. M. données sont acquis des échos de gradient. Des échos multiples peuvent être employés pour extraire des informations (telles que le contenu et la susceptibilité de volume) sur le matériel à l'étude.
