摘要
胰腺癌是一种起源于胰腺外分泌组织的肿瘤,多为导管腺癌;早期隐匿、侵袭性强、易转移、生存率低为其主要特点,这些特点也为早期诊断和治疗带来了挑战。近年来随着功能MR成像技术的发展,为人们进一步认识、了解胰腺癌提供了基础,尤其是MR扩散加权成像、动态增强扫描及波谱等技术的应用明显提高了病灶检出的敏感性,有助于了解胰腺癌的微循环灌注及细胞代谢情况,并能对抗血管治疗的疗效进行监测。
Pancreatic cancer is a tumor originated from the pancreatic exocrine tissue, mostly ductal adenocarcinoma. It shows characteristics of early concealment, high invasiveness, easy metastasis, and low survival rate. Its early diagnosis and treatment is still a challenge. In recent years, with the rapid development of MRI techniques, the MRI, especially the magnetic resonance diffusion weighted imaging, dynamic contrast enhanced MRI and spectrum, could provide a tool for us to further understand pancreatic cancer, and could significany improve the sensitivity of lesion detection. It helpful in evaluating the pancreatic microcirculation perfusion and cell metabolism, can assess the response to the antiangiogenic therapy, and has become an important tool in clinical practice.
