Q:
I'm going to ask about gating again just for some clarification. This, this person watching tonight said he recently had an MRA where a belt was wrapped around his midsection to measure his breathing. It seemed as though images were often taken at the end of exhaling. Is that what you mean by gating and if so is there a better way to get that would produce better images?
心電図同期についての質問です。「MRAの撮影時、呼吸測定のために体の中央部にベルトを巻かれていたが、息を吐き終わった段階で撮影されることが多かったような気がした」とのことです。これが同期MRAなのでしょうか？そうだとしたら、鮮明な画像を撮影するための良い方法はあるのでしょうか？
A:
So exactly so you can gate for on this on the MRI, the, I think the image he got he or she got is what we call respiratory gated, EKG-gated navigator. What it does is we are gating for his breath hold, breathing and at the end of exhalation is when it acquires the data and a in a certain time of the EKG. That's the reason it takes almost five to ten minutes to acquire that image. He's right to their measuring is breathing here and they're making sure they acquired every time at the same time because that sensor that's on his body tells them when he's, when he's exhaled or not and then it acquires the image. Yes it's true. that's a good question, yeah I like it.
この方の検査で使われていたのは、呼吸同期法による心電図同期ナビゲーターと呼ばれるものです。この方法では、呼吸をモニタリングし、息を吐き終わった段階かつ特定の心電図の波形のタイミングにおいてデータを取得するものです。画像撮影に約5分から10分かかるのはそのためです。質問者さんのご指摘どおりです。体に取り付けたセンサーで息を吐き終わった状態をモニタリングし、そのタイミングで撮影しています。
