目的:探讨对颅脑病变患儿进行低剂量CT扫描的临床效果。方法 :对2012年2月~2015年2月期间我院收治的73例疑似颅脑病变患儿的临床资料进行回顾性研究。我院对这73例患儿分别进行常规剂量CT扫描与低剂量CT扫描,然后观察对比其病灶的表现与形态,病灶边缘的特征以及定性诊断结果,总结对疑似颅脑病变患儿进行低剂量CT扫描的有效性与安全性。结果 :我院对这73例患儿进行常规剂量CT扫描的结果显示,有68例发生颅脑病变的患儿,其检出率为93.2%。我院对这73例患儿进行低剂量CT扫描的结果显示,有67例发生颅脑病变的患儿,其检出率为91.8%。用这两种检查方法诊断小儿颅脑病变的检出率相比差异无显著性(P>0.05)。用这两种方法诊断颅脑病变患儿病灶的情况,病灶的性质,单发病灶边缘与形态的准确率相比差异无显著性(P>0.05)。结论 :对颅脑病变患儿进行低剂量CT扫描的检出率与进行常规剂量CT扫描的检出率基本相当。但进行低剂量CT扫描产生的辐射量更小,故其安全性更高。临床上可将进行低剂量CT扫描作为诊断小儿颅脑病变的首选方法。
Objective: To investigate the clinical effect of low-dose CT scan in children with craniocerebral disease. Methods: The clinical data of 73 suspected craniocerebral lesions admitted to our hospital from February 2012 to February 2015 were retrospectively studied. Our hospital on the 73 cases of children were routine dose CT scan and low dose CT scan, and then observe the performance of its lesions and morphology, the characteristics of the edge of the lesion and qualitative diagnosis, summarize the suspected low-dose craniocerebral lesions in children CT scan of the effectiveness and safety. Results: The results of conventional CT scan of 73 children in our hospital showed that there were 68 cases of children with craniocerebral lesions, the detection rate was 93.2%. Our hospital on the 73 cases of low-dose CT scan results showed that 67 cases of children with craniocerebral disease, the detection rate was 91.8%. There was no significant difference in the detection rate of craniocerebral lesions between these two methods (P> 0.05). There was no significant difference between the two methods in diagnosing lesions of children with craniocerebral lesions, the nature of lesion and the accuracy of margins and forms of single lesions (P> 0.05). Conclusion: The detection rate of low-dose CT scan in children with craniocerebral lesions is basically the same as that of routine CT scan. However, low-dose CT scan radiation generated smaller, so its more secure. Clinically, low-dose CT scan can be used as the preferred method of diagnosis of children with brain lesions.
