PDFAbstract
Objective To investigate the value of MRI and CT in the clinical diagnosis of acute closed craniocerebral injury and the differences in imaging features. Methods 132 patients with acute closed craniocerebral injury were enrolled in the study. After admission, all patients underwent MRI and CT examination, and the imaging features were compared. Results The imaging features of CT and MRI were basically coincident in soft tissue injury, primary hemorrhage and primary nerve injury. CT was more sensitive than MRI in displaying skull fractures. There were free bone fragments in patients with comminuted fractures, and there were skull bone plate discontinuity and part of the skull gap widening in patients with line-like fractures. MRI showed low signal shadow on T1 and T2 weighted images. Conclusion The imaging features of CT and MRI are similar in soft tissue injury, primary hemorrhage and primary nerve injury type of craniocerebral injury. The value of CT is higher than MRI in the differential diagnosis of skull fractures. The combined use is suggested to improve the diagnostic accuracy.
