AI Technical Summary
The existing coronary magnetic resonance imaging (MRA) technology requires subjects to hold their breath during examination, and it is difficult for older subjects or weak cardiopulmonary function to cooperate, resulting in a decrease in imaging quality. At the same time, imaging based on blood-brightening technology lacks clear signal comparison, making it difficult to clearly identify plaque characteristics related to coronary stenosis.
The MRA scanning mechanism and black blood imaging technology with breath navigation gating were introduced to replace the traditional breath-holding MRA scanning mechanism. Bright hemogram was performed by respiratory navigation gating 3D sBTFE sequence coronary magnetic resonance imaging and reworked until qualified if the imaging quality was not up to standard. If stenosis is present, black blood imaging is further performed by DIR FSE sequence coronary magnetic resonance imaging to identify coronary plaque characteristics.
A MRA examination without breath holding is achieved, which improves the examination efficiency; and the recognition quality of coronary stenosis and plaque characteristics is improved through black blood imaging technology.
