Cyclotron resonance scattering features (CRSF) are the direct observational evidence for the strongly magnetized neutron stars. Since the first detection of the absorption line in the X-ray source Her X-1 thirty years ago, more than ten sources are indentified as the strongly magnetized neutron stars through detecting CRSFs. INTEGRAL is the new X-ray/gamma-ray mission with good angular resolution, high sensitivity and spectral resolution in the range of 18 C 200 keV, so that it provides us a good chance to detect the CRSFs in neutron star systems. INTEGRAL has confirmed the line features in 5 previous known sources and discovered 4 new candidates. Physical mechanism of CRSFs and accretion physics can be probed with detailed spectral analysis.
