There is little clinical cervical functional MR study, especially about cervical MR perfusion weighted imaging(PWI) and diffusion tensor imaging(DTI) in cervical tumor-like lesions, although there were advanced development in MR hardware and sequence. Our study is to evaluate the application of MR PWI and DTI in tumor like lesions of the cervical spinal cord. 8 patients were enrolled in this study. The relative cerebral blood volume (rCBV) and Fractional anisotropy (FA) of lesions and normal tissues were analyzed. There are 4 patients with increased perfusion and 4 patients with decreased perfusion including one patient of cervical radiation injury, the lesion was enhanced after contrast and MR PWI revealed progressive decreased perfusion. All lesions were with decreased FA values. Our study proves that MR PWI and DTI are available for the cervical spinal cord tumor like lesions; combining cervical PWI and DTI could supply perfusion information and decreased anisotropy of these lesions, which are important fo
