Center K refocusing flip angle

The Cube Enhance User CV is used to customize the internal Cube parameters to produce particular contrast for specific anatomy. This CV applies to Cube T2, but not Cube FLAIR .

If, and only if, User CV 22 (MSK2 PD3) is selected and set to 1, another User CV (CV 12: Center K Refocusing Flip Angle) is opened.

The value selected determines the minimum flip angle of the refocusing RF pulse.

  • A smaller flip angle reduces image blurring with a tradeoff of reduced SNR.
    Figure 1. Knee example with User CV 12 set to 30 degree flip angle
  • A larger flip angle increases the SNR with a tradeoff of increased image blurring.
