Zusammenfassung
Purpose: To determine suitable parameters for rapid DTI acquisition at 3 tesla, to assess the reproducibility of fa-measurements which are one of the core information for fiber trackings, and to quantify the influence of noise reduction and averaging high b-values on resulting FA-maps. Methods: The study collective consisted of 10 volunteers for the issue of sequence optimization and 2 volunteers for reproducibility assessment and testing for the use of noise decorrelation and high b averaging. Concerning sequence optimization, the following constant parameters were used: a single shot SENSE imaging protocol wit…
