在溃疡性结肠炎或Crohn结肠炎的急性发作期,单以临床检查估测肠段受累的广泛程度并不可靠。此时又不应作侵入性检查,因后者可使病情恶化。作者提出~(111)铟-白细胞扫描,可用于确定炎症的部位和活动度。~(111)铟-自体白细胞被重新注入体内后移向炎性病灶,可用γ-扫描仪检测其放射性。作者将检查结果和钡剂灌肠、结肠镜及手术发现作了比较。采患者血液,分离多形核粒细胞,用~(111)铟-标记后
In the acute episodes of ulcerative colitis or Crohn’s colitis, it is unreliable to assess the extent of bowel involvement solely by clinical examination. At this time should not be used for invasive examination, because the latter can make the disease worsened. The authors propose a ~ (111) indium-leukocyte scan that can be used to determine the site and extent of inflammation. ~ (111) indium - autologous leukocytes are reinjected into the body and then migrate to inflammatory lesions. Radioactivity can be detected by γ-scanner. The authors compared the findings with barium enema, colonoscopy, and surgical findings. Patient blood was collected and polymorphonuclear granulocytes isolated using ~ (111) indium-labeled
