【摘要】：目的探讨16层螺旋CT低剂量扫描在新生儿头颅检查中的临床应用。方法选择2015年1月~2016年6月在我院进行头颅检查的新生儿106例作为研究对象,按照入院先后顺序,将其分为第一组与第二组,各53例。第二组行120 KV/90 MAS扫描,第一组行120 KV/260 MAS扫描患者,CT准直为1.5 mm,层厚6 mm,重建间隔6 mm,床速11.7 mm/r,扫面时间为0.75 s,对比两组16层螺旋CT不同剂量的扫描效果。结果第一组CTDLW和DPL分别为17.29 m Gy、245 m Gy.cm,第二组CTDLW和DPL分别为49.86 m Gy、712m Gy.cm,第二组的CTDLW和DPL均明显优于第一组,差异有统计学意义(P0.05)。常规的剂量扫描和低剂量扫描占据的比例比较,差异无统计学意义(P0.05)。结论在新生儿头颅临床检查之中,与常规剂量扫描相比较,16层螺旋CT低剂量扫描为其35%,图像不会对诊断造成影响,该检查方法适用于新生儿头颅检查之中,具有较广的发展前景。
[Abstract]:Objective to investigate the clinical application of low dose 16-slice spiral CT scanning in the cranial examination of newborns. Methods 106 cases of neonates with head examination from January 2015 to June 2016 in our hospital were selected as research subjects. The object. According to the order of admission, the patients were divided into the first group (53 cases) and the second group (53 cases). The second group underwent 120 KV/90 MAS scan and the first group received 120 KV/260 MAS scan. Ct collimation was 1.5 mm, slice thickness was 6 mm, reconstruction interval was 6 mm, bed velocity was 11.7 mm / r, scan time was 0.75 s. Results in the first group, the CTDLW and DPL were 17.29 m Gy.cm and 245 m Gy.cm, respectively. The CTDLW and DPL of the second group were 49.86 m Gy 712m Gy.cm, respectively. The CTDLW and DPL of the second group were significantly better than those of the first group. The difference was statistically significant (P 0.05). There was no significant difference between conventional dose scan and low dose scan (P 0.05). Conclusion there is no significant difference in the clinical examination of the head of newborn. Compared with conventional dose scan, 16-slice spiral CT with low dose scan is 35%, and the image will not affect the diagnosis. This method is suitable for neonatal cranial examination and has a broad prospect of development.
