Fifty patients with no small-bowel disease were evaluated by CT to determine the normal appearance of the small bowel and mesentery. Subsequently, the CT findings in 95 patients with proven small-bowel disease were analyzed to determine which CT observations correlated with neoplastic, inflammatory, or edema-producing processes. Thirty-three (83%) of 40 patients with wall thickening or mesenteric masses greater than 1.5 cm had a neoplastic process. Twenty-eight (82%) of 34 patients with normal mesenteric fat attenuation, wall thickening less than 1.5 cm, or mesenteric masses less than 1.5 cm had inflammatory disease. Fourteen (67%) of 21 patients with no mesenteric mass, increased mesenteric fat attenuation, and wall thickening less than 1.5 cm had noninflammatory edema. Overall, CT assigned 75 (79%) of 95 patients into appropriate categories; use of ancillary CT findings led to correct categorization in 83 (87%). CT is helpful in correctly assigning a disease category to patients with small-bowel wall thickening.
对50例无小肠疾病的患者进行CT检查，以确定小肠和肠系膜的正常表现。随后，对95例经证实患有小肠疾病的患者的CT检查结果进行分析，以确定哪些CT表现与肿瘤、炎症或产生水肿的过程相关。40例肠壁增厚或肠系膜肿块大于1.5 cm的患者中，33例（83%）有肿瘤性病变。34例肠系膜脂肪密度正常、肠壁增厚小于1.5 cm或肠系膜肿块小于1.5 cm的患者中，28例（82%）有炎症性疾病。21例无肠系膜肿块、肠系膜脂肪密度增加且肠壁增厚小于1.5 cm的患者中，14例（67%）有非炎症性水肿。总体而言，CT将95例患者中的75例（79%）归入适当类别；使用辅助CT表现可使83例（87%）正确分类。CT有助于对小肠壁增厚的患者正确分类疾病类别。
