穿刺抽吸活检,能得到细胞学和组织学检查的材料.电子计算机断层扫描能准确地查明病灶的大小和定位,特别是腹腔和腹膜后间隙的病变。在电子计算机断层扫描监视下,瞄准穿刺活检,大部分能在无损伤的条件下相当快地明确诊断. 先进行普通检查,查明肿瘤,并从断层X线照片 Puncture aspiration biopsy, cytology and histological examination of the material available.Computer tomography can accurately identify the size and location of the lesion, especially the peritoneal and retroperitoneal space lesions. Under computerized tomography surveillance, aiming for a biopsy, most can be definitively diagnosed fairly quickly without injury. First, a routine examination is performed to identify the tumor and to determine the tumor from a tomographic
