- 摘要：
PROBLEM TO BE SOLVED: To reduce artifacts due to the difference of an abdominal area position every time of holding breath and to improve the diagnostic ability of images in breath holding cine imaging to which CSPAMM is applied.
SOLUTION: The control part of the MRI system is provided with a cine imaging sequence accompanied by two kinds of tagging prepulses of different RF applying conditions, and changes the RF applying condition for each slice or for each cardiac cycle in the fixed time equivalent to the breath holding time of an object. Thus, entire k space data by the cine imaging sequence of a first RF impressing condition and entire k space data by the cine imaging sequence of a second RF applying condition are acquired for one slice within the fixed time and positional deviation artifacts in CSPAMM images are reduced.
