Objective To explore to metal artifacts sequence thoracic vertebrae in patients with metal implants affect magnetic resonance images. Methods January 2014 -2015 period January hospital treated 25 cases of thoracolumbar spine (lumbar, thoracic) in patients with metallic implants, all patients with thoracolumbar conventional MRI sequences and go metal artifact scanning sequence, and using paired t test for two sequences check scanning time and image quality scores were analyzed and compared. Results Signal to the surrounding soft tissue image sequences metal artifacts loss mitigation metal implants, and the image is blurred and deformation sequence compared to conventional metal artifacts serious image sequences. General sequence of image quality score of (3.56±0.53) points to the metal artifacts sequence of image quality score of (4.22±0.67) points, compare the difference between the two groups was statistically significant (p<0.05). Lumbar metal artifacts sequence check time for 11min53s, conventional sequence check time for 9min16s, compare the difference between the two groups was statistically significant (p<0.05). Thoracic metal artifacts sequence to check the time for 12min45s, conventional sequence check time for 8min16s, compare the difference between the two groups was statistically significant (p<0.05). Conclusion To metal artifacts sequence checking technology can significantly improve image quality and reduce artifacts MRI metal implants, metal implants in patients with spinal MRI has a very significant impact.
