HEART WALL MOTION ANALYSIS AND DISPLAY USING MRI TAGGING
T. Morito, Y. Hiraki, H. Yamamoto
Abstract:
In this paper, we developed a left ventricular (LV) wall motion analysis method, and developed a display method of the motion on personal computer monitor.
To know precise rotation or deformity, identifiable landmarks must be located. The MRI tagging makes it possible to estimate the regional wall motion noninvasively. We tried to estimate the precise LV wall motion by the MRI tagging.
Tagging is achieved by selective saturation pulse method. The difference of the signal intensity between tagged and nontagged regions persist for 400-700 milliseconds.
We display the tag point movement as animation, and display the rotation & contraction curve on the same computer monitor.
