Abstract：Objective:To investigate the clinical value of CT in diagnosis of subdural hematoma.Method:50 cases of subdural hematoma used the U.S. GE whole body CT Scanner,matrix was 256×256,thickness was 1.0 cm,scan time was 4.8 seconds.50 cases in 18 cases was took simultaneously enhanced scan, 60%contrast agent Diatrizoate,per kilogram of body weight immediately after scanning 1-2 ml intravenous bolus injected pressure,level was with enhanced front. Result:In 50 patients after the scan,48 cases diagnosed with subdural hematoma,2 cases diagnosed after enhanced scan and follow-up,scan diagnosis rate was 96%. hematoma shapes were 53,acute and subacute hematoma was 19,showed a crescent-shaped hematoma,Chronic subdural hematoma was 34,8 crescent-shaped,14 showed a half-moon,12 double-convex.11 acute hematoma hematoma density were high density,5 for high-density in 8 subacute hematoma,mixed-density 3.34 chronic hematoma 9 mixed density,21 of equal density,low density 4.Acute subdural hematoma with high-density-based,subacute and chronic subdural hematoma lower high-density ratios,such as density or mixed-density ratio increases.Conclusion:CT scans can increase the rate of clinical diagnosis of subdural hematoma,provide the basis for clinical treatment.
