Abstract
Objective To investigate MRI susceptibility weighted imaging(SWI)sequence on diagnostic value and clinical significance of spinal cord injury. Methods 52 cases admitted from Jan.2012 to Dec.2013 were collected. They underwent routine MRI sequence and SWI scanning. The conventional sequences and SWI for displaying hemorrhage were analyzed and compared. The patients were followed. Results The display rate of SWI scan for edema, contusion, and bleeding was significantly higher than that of the conventional group. The difference had statistical significance(P<0.05). SWI scanning imaging time was shorter than that of the conventional group. The difference had statistical significance(P< 0.05). The type of spinal cord injury was mostly edema, accounting for 38.5%, significantly more than hemorrhage, necrosis and thickening. Conclusion SWI is more sensitive and clear in displaying bleeding caused by spinal cord injury compared to the conventional MRI sequence, which is an important inspection method in spinal cord injury. Key words: Magnetic resonance; Susceptibility weighted imaging; Spinal cord injury
