①用二甲肼诱发大鼠结直肠肿瘤33个,水槽内7.5MHz超声检出最小膊润粘膜层的患肉样良性病变21.2%,粘膜下层早癌36.4%,肌层浆膜层中晚期癌4 5.5%,肿瘤生物学行为超声图像特征与病理诊断符合率96.9%.位于粘膜层的原位癌.粘膜肌层的早癌超声无法辩认.病理所见腺癌为主与人类肠癌相似,故鼠肠癌大体所见超声图像及病理为肠癌早期诊断提供超声病理基础,超声对胃肠肿瘤标本的超声分期正率达86.4%.②用自行研制大肠超声显像液灌注(UBCE)为腹部B超检查提供良好声窗,图像清晰,增强病人对大剂量保留灌肠的适应力,经x线气钡双重造影,纤维肠镜手术病理验证UBCE超声检查诊断大肠肿瘤是安全、实用的好方法.

Thirty three colorectal iummors were induced by dimethynlydraztne(DMhi,1n white rats,The smallest lesion examined by US with high frequency transducer in the Waler was 2-3mm.The Co-incidenee rate of ultrasonic diagnosis with pathological diagnosis WaS 96.9% But there Was differ- ence between carcinoma in situ and in muscular layer of mucosa by US.Adnocarcinomas and their histopathological characteristic of white rats were similar those of human large bowel tumor.This experimental study providod the ultrasonic and pathoiogical basis to diagiose early colorectal cancers in clinic.The accuracy rap2 of the gastrointeslinal eancer sperimens siaging by US was 36.4%.Verified by barium enema and airbarium double contrast radiography or fibercolosctnv,abdomhnl US was a valuable and safe method for diagnosing during UBCE.
