  • iTFlow (4D Flow MRI)
    Is it possible to analyze 2D Phase Contrast MRI?
    It is possible. Energy loss and flow rate are analyzed in two-dimensional units.
  • iTFlow (4D Flow MRI)
    What are the advantages and disadvantages of 2D Phase Contrast MRI?
    Since the analysis results are limited to 2-dimensional cross-sections, the desired analysis results cannot be obtained if the characteristic flow, for example, the central axis of the stenotic jet is not captured in the cross-section.
    On the other hand, it takes less time for acquisition.

  • iTFlow (4D Flow MRI)
    2D Phase Contrast MRIの解析は可能か。
    可能です。エネルギー損失や流量は二次元の単位での解析となります。
  • iTFlow (4D Flow MRI)
    2D Phase Contrast MRIのメリット、デメリットとは。
    解析結果が2次元断面に限られてしまうため、例えば狭窄ジェットの中心軸を捉えられていないなど特徴となる流れが断面内に入らないと望んだ解析結果が得られません。一方、撮像にかかる時間が短く、4D Flow MRIのシーケンスが入っていない相違でも撮像できるメリットがあります。
