实验研究已证明高强度聚焦超声(HIFU)提供了一种局部切除肿瘤的体外治疗手段.本文选择不同方案的HIFU治疗H_(22)肝肿瘤.73只ICR H_(22)肿瘤荷鼠分对照组和HIFU治疗组.后者根据辐照时间和次数变化分不同治疗亚组.结果显示HIFU对各治疗组小鼠H_(22)肿瘤生长均有抑制作用.同一声强下,切除肿瘤的局部效果取决于辐照时间和次数.
Experimental studies have demonstrated that high-intensity focused ultrasound (HIFU) provides an in vitro therapeutic method for local resection of tumors. In this article, we selected different regimens of HIFU to treat H_(22) liver tumors. 73 ICR H_(22) tumor mice were divided into control groups. In the HIFU treatment group, the latter group was divided into different treatment subgroups according to the irradiation time and frequency. The results showed that HIFU inhibited the growth of H22 tumors in each treatment group. Depends on irradiation time and times.
