磁共振弥散加权成像术在腹膜转移癌诊断中的应用价值

腹膜转移癌患者的预后较差，良好的影像学评估方法有助于其治疗方案的选择和治疗疗效的评估。腹膜转移癌在磁共振弥散加权成像术检查图像中表现为较之周围组织明显的高亮信号，与CT检查相比能明显提高腹膜癌的检出率，尤其是小转移癌灶以及膈下、肝包膜下、网膜囊、肠系膜根部和肠管浆膜表面的腹膜癌的检出率。

The application of diffusion-weighted magnetic resonance imaging in the diagnosis of peritoneal carcinomatosis

Peritoneal carcinomatosis is invariably associated with a poor prognosis. A good imaging evaluation method can beneift the options of individualized treatment and the assessment of curative effect. Peritoneal carcinomatosis is manifested as obvious highlight signal compared with the surrounding tissues on the magnitude diffusion-weighted images. Diffusion-weighted magnetic resonance imaging, compared with CT, can signiifcantly improve the accuracy in the detection of peritoneal cancer, especially for the small metastatic foci and the peritoneal cancers on some special anatomical sites under the diaphragm and liver capsule and of omental capsule, mesenteric root and intestinal serosal surface.
