摘要
为了评价频率不同的探头对阑尾炎的诊断水平,选用3.5MHz和7.5MHz软探头,对30例健康人阑尾和40例病变阑尾进行对比扫查。3.5MHz探头,正常阑尾无1例显现,病变阑尾显现率为52.5%。7.5MHz软探头,正常阑尾显现率为36.67%,病变阑尾显现100%,高频超声提高了阑尾显现率和诊断水平。
In order to eveluate diagnostic value of different frequency ultrasound in appendicitis. 3. 5MHz probe and 7. 5MHz probe were used to comparatively scan sick and normal appendix. The results demonstrated that no normal appendix was manifested and the detective rate of sick appendix was 52. 50% with 3. 5MHz probe. But the detective rate of normal appendix was 36. 67% and sick appendix was 100% with 7. 5MHz probe. We conclude that the detective rate of appendix was significantly elevated with high frequency probe.
