Objective:To compare the variation of titanium implant artifacts in different sequences and optimize scanning parameters for high-quality images. Methods:Titanium water phantom was designed for routine sequences and those with optimized parameters scanning;the variation of artifacts was observed with altering field of view,echo train length,bandwidth in sagT2-FSE sequence. Results:Artifacts were changed under different sequences. The reduction of field of view,the decrease of echo train length and bandwidth reduced the artifacts. Conclusion:Change of the scan sequence or scan parameters could reduce artifacts caused by metal implants,improve image quality,and benefit clinical diagnosis.
