低剂量CT扫描颅内出血性疾病

Low-dose CT Scanning of Intracranial Hemorrhagic Disease

目的探讨低剂量CT扫描在颅内出血性疾病复查时扫描的应用价值。并研究低剂量扫描在临床诊断中的可行性。方法采用德国西门子公司生产的16排螺旋CT,通过降低管电流来降低扫描剂量,对60例颅内出血性疾病患者复查扫描。其中30例采用常规扫描,另外30例采用低剂量扫描。将低剂量扫描的图像与首次检查图像比较,评价出血性疾病的发展情况。再与常规扫描比较影像学差异。结果低剂量CT扫描所获得的图像清晰,与首次扫描的图像相比,对比度、病灶边缘显示无明显差异,不影响病灶的显示和诊断结果。与常规扫描图像无明显影像学差异。结论低剂量CT扫描对病人的辐射剂量大大降低了。由于采用低剂量扫描,CT机器的消耗也降低了,大大增加了机器的使用寿命。

Objective To explore the application of low-dose CT scanning in intracranial hemorrhagic disease. To study the feasibility of low-dose scans in the clinical diagnosis. Methods German Siemens 16-slice spiral CT was used. The scanning dose was reduced by reducing the tube current. 60 cases with intracranial bleeding diseases underwent CT scanning. 30 patients underwent conventional CT scanning, and another 30 cases underwent low-dose CT scanning. Low-dose CT images were compared to the first checked images to evaluate the development of hemorrhagic disease, and compared with conventional CT scanning images. Results Compared with the first scanning images, low-dose CT scanning images showed no significant difference, and the quality of images did not affect the display of lesions and diagnosis. There was no significant difference compared to conventional CT images. Conclusion The patient＇s radiation dose was significantly reduced by low-dose CT scanning. As a result of low-dose scanning, the consumption of CT machine was also reduced, which could greatly increase the life of machine.
