Abstract
Objective To explore the clinical application value of the dual source CT dual energy scanning linear fusion technology for eliminating lumbar metal implants artifacts. Methods 33 patients that were going to check after lumbar metal implants were selected for our research. The dual source CT dual energy scanning with the voltages were separately 80 kV and 140 kV was used to gain the imaging data for linear fusion, which we marked as group A. The regular 120 kV imaging data was simulated, which we marked as group B. Multiple planar reconstruction, volume reality, maximum intensity projection, reconstruction image quality and the artifacts were evaluated. Results The images with high quality under linear fusion were 90% and 33%, respectively. The images with no artifact in group A and B accounted for 91% and 36%, respectively. The difference between group A (Z=5.74, P=0.00) and group B (Z=6.74, P=0.00) was statistically significant. Conclusion It was very accurate and effective for the dual source CT dual energy scanning linear fusion technology to eliminate lumbar metal implants artifacts. It could clearly show the location shape, and other microscopic structures of the lumbar metal fixture. In addition, it could clearly show right and left psoas muscles without artifacts interference. Therefore, the dual source CT dual energy scanning linear fusion technology can obtain high quality images and meet the diagnostic requirements.关键词
