摘要
目的 探讨螺旋CT(SCT)增强扫描对腹膜转移瘤的诊断价值。方法 经手术病理证实为腹膜转移瘤的患者 38例 ,术前 1周内行全腹CT平扫及SCT增强扫描。分析CT扫描所见 ,并与手术病理所见进行对照。结果 在SCT增强早期 ,大多数腹膜转移瘤表现出不同程度的强化 ;目测原发肿瘤与转移灶有相同程度的强化 ;对血供丰富的肿瘤 ,SCT增强扫描可显示 2mm的种植灶。CT平扫及SCT增强扫描对腹膜转移瘤总的敏感性分别为 4 6 .7%和 76 .6 % (P <0 .0 0 5 ) ,对附件、膈下、小肠系膜、横结肠系膜与大网膜 ,SCT增强扫描对腹膜转移瘤的检出率 >83%。结论 SCT增强扫描诊断腹膜转移瘤优于CT平扫 ,是诊断腹膜转移瘤有效的影像检查方法。
Objective To compare enhanced spiral computed tomography (SCT), and plain CT with pa thological findings in the diagnosis of peritoneal metastasis. Methods Thirty eight patients with peritoneal metastasis were examined by whol e abdominal plain CT and enhanced SCT within one weeK before operation. The CT findings were compared with the pathological findings of specimens obtain ed during operation. Results In the early phase of contrast SCT, various degrees of enhanceme nt were observed in the majority of peritoneal metastases. Primary can cers and the metastatic lesions were enhanced to same degree. For lesions with rich blood supply , a 2 mm metastatic lesion was usually detected by cont rast SCT. The sensitivity of plain CT and enhanced SCT for the detection of per it oneal metastasis in all involvements were 46.7% and 76.6% ( χ 2 = 29.07, P < 0.005). For contrast SCT, the detection rates o f per itoneal carcinomatosis were higher then 83% in the fallopian tubes, ova ry , subphrenic spaces, mesentery of small intestine, transverse colon and omentu m. Conclusion Enhanced spiral CT, being superior to plain CT, is effective in detecting and di agnosing peritoneal metastasis. [
