| 目的 分析急性脑梗死的CT表现。 方法 105例急性缺血性脑梗死病例,在其接受治疗过程中即发病后第3、11、21 天和在出院后随访各做头颅CT 平扫一次。分别计算病灶的面积和密度的改变程度。 结果 ①发病后72h内,病灶CT值的改变程度平均下降23.8%,病灶的面积平均为11.2cm2。②经治疗后在发病后的第11天,第21天病灶面积分别平均缩小了37.5%和39.8%,病灶CT值分别恢复了18.2%和17.1%。③出院后随访:病灶基本消失者占30%,面积明显缩小(缩小60%以上)者为22%,余48%的病灶呈小斑片状。 结论 普通CT机在急性缺血性脑梗死病例的诊断、疗效评估及随访中提供了有意义的信息。 |

| Objective The aim of this study was to analyze the CT findings of acute ischemic cerebral infarction. Methods During the process of treatment, one hundred and five patients who were dignosed as acute ischemic cerebral infarction. All cases underwent CT plain scan on the third, eleventh, twenty-first day after the symptom onset and one time follow-up after discharging from hospital. The CT numbers and the areas of the lesions and their corresponding parts on the oppsite side were measured and compared. Results ① In 72 huors after the symptom onset, the radiodensity decreased 23.8% when compared to its oppsite part. The mean area of lesions was 11.2cm2. ② On the eleventh and twenty-first day, the areas of the lesions contracted 37.5% and 39.8% and the CT numbers increased 18.2% and 17.1% correspondingly. ③ Follow-up after discharging from hospital: 30% of the lesions were basically disappeared, 22% of the lesions contracted more than 60% of their areas, the rest 48% of the lesions showed the pachy lesions left. Conclusion Conventional CT provides signifinant information in the diagnosis, the evaluation of the treatment and the follow-up of acute ischemic cerebral infarction. |
