Improvement of the Perfusion Analysis by Registration of MRI Images Sequence

C. Dornier, M.K. Ivancevic, P. Thévenaz, J. Vallée

Proceedings of the Nineteenth Annual Scientific Meeting of the European Society for Magnetic Resonance in Medicine and Biology (ESMRMB'02), Cannes, French Republic, August 22-25, 2002, published in MAGMA Magnetic Resonance Materials in Physics, Biology and Medicine, vol. 15, sup. 1, pp. 105, August 2002.



Myocardial perfusion can be measured from the transit time curves obtained by MRI and contrast media injection. The registration of the dynamic images of MR perfusion study is the first step of this analysis that is usually done manually. This work describes an automatic registration process that overcomes the difficulty related to time dependent intensity variations inside the heart section to be registered.
