Real-time free-breathing cine imaging is highly
desirable in cardiac patients for LV function
quantification. However, volumetric measurement is prone
to be erroneous due to respiratory motion. In this
study, we proposed an efficient approach to identify ED
and ES phases at end-expiration semi-automatically.
Twelve healthy volunteers were scanned using the
real-time cine imaging and processed with the proposed
method with the standard breath-hold cines as reference.
Results showed that the measured LV function was
comparable between the two imaging protocols, suggesting
the proposed method to be efficient and reliable in
analyzing real-time cines.
