随着各类放射诊疗新设备、新技术与日俱增且不断普及,医疗照射频率也不可避免地剧增。在保证影像诊断质量的前提下,如何尽可能降低受照剂量也成为如今的研究热点。由于儿童和婴幼儿造血细胞和骨骼正处于发育的活跃状态,接受放射线要比成年人敏感得多,如果反复照射,可能会引起部分机体细胞受损,如免疫力下降、白细胞降低、造血功能障碍等。因此,尽可能降低儿童影像学检查的辐射剂量尤为重要。我们总结了2010年1月至2012年12月于我科接受检查的3 842例患儿检查情况,
With all kinds of new radiotherapy equipment, new technologies and ever-increasing popularity, the frequency of medical exposure will inevitably surge. Under the premise of ensuring the quality of diagnostic imaging, how to reduce the dose as much as possible has become a research hotspot nowadays. Since hematopoietic cells and bones in children and infants are in an active state of development, radiation exposure is much more sensitive than in adults. Repeated irradiation may cause damage to some of the body’s cells, such as decreased immunity, leukopenia and hematopoietic dysfunction Wait. Therefore, it is particularly important to minimize the radiation dose for imaging studies in children. We summarized 3 842 cases of children undergoing examination in our department from January 2010 to December 2012,
