Title:
【発明の名称】コントラスト増幅型磁気共鳴血管造影法におけるコントラストの検出および誘導される再構築
Document Type and Number:
Japanese Patent JP2002533144
Kind Code:
A
Abstract:
A dynamic MRA study is performed using a 3D fast gradient recalled echo pulse sequence. A signal strength indicator for each acquired k-space data set is calculated and these indicator values are employed to produce a contrast curve. This contrast curve is used to select data for use in forming a CONTRAST k-space data set and a MASK k-space data set. The MASK is subtracted from the CONTRAST data set and the result is used to reconstruct an image.
