探讨磁共振血管成像术对胰腺癌侵及血管的判断。方法：对胰腺癌术前进行磁共振血管成像检查并对病灶与门静脉血管进行分级判断，将其与术中发现或病理结果相对照。结果：根据磁共振血管成像将肿瘤与门静脉血管关系分为０级２例；Ｉ级３例，Ⅱ级３例，Ⅲ级２例；其中行根治术者３例，根治切除并血管重建４例，内引流术３例。结论：术前磁共振血管成像可提供可靠的肿瘤与门静脉血管关系的影像学资料，对指导手术选择有重要价值。
To explore the magnetic resonance angiography in pancreatic cancer invasion and blood vessels judgment. Methods: Preoperative magnetic resonance angiography (MRI) was performed on pancreatic cancer and the lesion and portal vein were graded, and compared with the results of intraoperative findings or pathology. Results: The relationship between tumor and portal vein was classified as grade 0 in 2 cases according to magnetic resonance angiography. There were 3 cases in stage I, 3 cases in stage II and 2 cases in stage III. Among them, 3 cases underwent radical resection and revascularization in 4 cases , Internal drainage in 3 cases. Conclusion: Preoperative magnetic resonance angiography can provide reliable imaging data of the relationship between tumor and portal vein blood vessels, which is of great value in guiding the choice of surgery.
