Motion of thoracoabdominal region due to respiration causes image blur in nuclear imaging modalities such as PET and SPECT. On the other hand, capturing or monitoring such motion provides us useful information. For example, monitoring such motion makes respiration-gated PET and SPECT possible and thus yields less- blurred images. Furthermore, motion of thoracoabdominal region due to respiration may provide us effective information on lung or liver diseases. We have developed a method for estimating lung motion from respiration-gated PET and tried to relate the motion with lung diseases. Recently we have developed a method for reconstructing a four-dimensional magnetic resonance image (4DMRI) of respiratory organ motion from time sequential images of two-dimensional (2D) MR. Those images can also used for dynamic 3D image analysis of thoracoabdominal region. Those techniques are introduced.
