Application of Molecular Imaging Equipment PET/MRI

To compare the principles and system frameworks on PET and MRI systems. The functional characteristics and present adoptive structural models of PET/MRI as molecular imaging equipment is introduced in particular. To compare several update techniques of attenuation correction for PET image with MRI parameters and to expatiate their deficiencies. The advantages on PET/MRI clinical applications and the future development of PET/MRI are introduced briefly.
