目的 了解MRA(磁共振血管造影术 )、MRI、CT等影像学检查在判断骨与软组织肿瘤致血管解剖位置改变的价值和意义。方法 回顾性总结我院 1998～ 2 0 0 0年期间行MRA等影像学检查的 7例骨与软组织肿瘤患者的资料。结果 MRA可清晰显示肿瘤与邻近重要血管的解剖关系 ,显示其供血血管的起源、分布和位置 ,为手术方案的选择设计、减少术中出血和避免损伤重要邻近血管提供优于CT、MRI及X光片的信息。结论 MRA在骨与软组织肿瘤的治疗中具有非常重要的指导参考价值 ,尤其对于恶性肿瘤拟行保肢术 ,危险部位肿瘤或特殊部位肿瘤的治疗更是如此。
Objective To understand the value and significance of MRA (magnetic resonance angiography), MRI, CT and other imaging examinations in judging the change of vascular anatomy caused by bone and soft tissue tumors. Methods We retrospectively summarized the data of 7 patients with bone and soft tissue tumors who underwent MRA and other imaging examinations in our hospital from 1998 to 2000. Results The MRA can clearly show the anatomical relationship between the tumor and adjacent vital blood vessels, showing the origin, distribution and location of its blood supply vessels, providing better choices for surgical planning, reducing intraoperative bleeding, and avoiding injury to vital adjacent blood vessels to provide advantages over CT, MRI, and X. Light sheet information. Conclusion MRA has very important guiding value in the treatment of bone and soft tissue tumors, especially for the purpose of limb salvage for malignant tumors, especially for the treatment of dangerous-site tumors or tumors at specific sites.
