Abstract：Objective To explore the application value of multi-slice spiral CT (MSCT) multiplanar reformation (MPR) in observing the leakage of bone cement after percutaneous kyphoplasty (PKP). Methods The multiplanar reformation images of MSCT and images of digital radiography of 21 vertebrae with bone cement leakage after PKP were retrospectively analyzed, including 6 thoracic vertebrae and 15 lumbar vertebrae. Results 21 vertebrae were determined as bone cement leakage with MSCT MPR, including 4 cases located in vertebral vein, 4 cases located in intervertebral disc, 6 cases located in spinal canal, 7 cases located in paravertebral tissue. Among the 21 leakage of bone cement, 2 cases located in multi-site. The detection rate of MSCT MPR was 100%. At the same time, 15 vertebrae were determined as bone cement leakage with DR examination, including 3 cases located in vertebral venous, 4 cases located in intervertebral disc, 2 cases located in spinal canal, 6 cases located in paravertebral tissue, and 1 case located in spinal canal was diagnosed as suspected leakage of bone cement. The detection rate of DR examination was 71.42%. Conclusion These were no significant differences in observingⅠ, Ⅳ and Ⅴ types of bone cement leakage between MSCT MPR and DR. However, MSCT MPR was more comprehensive, intuitive and sensitive than DR in the observation of Ⅱand Ⅲ types of bone cement leakage. MSCT MPR which can show the amount, space and location of bone cement in spinal canal has an important clinical application value in estimating whether the leakage of bone cement can cause the injury of nerve root or spinal cord.
