【摘要】 目的 :探讨低场 MRI对腹主动脉瘤断的价值。材料和方法 :对 15例腹主动脉瘤患者用低场 MR机检查。结果 :15例中肾动脉上型 5例 ,肾动脉下型 10例 ,动脉瘤长度 5 .1～ 2 5 cm,平均 (10 .8± 4 .1) cm,动脉瘤最宽径 3.6～ 9.4 cm,平均 (5 .5 6± 1.85 ) cm。 5例清晰显示肾动脉开口 ,4例可见双侧髂总动脉受累 ,1例可见右肾动脉受累 ,15例均可见附壁血栓。MRI未显示动脉瘤壁及血栓上大小不等的钙化点。7例可见动脉瘤与正常腹主动脉交界处向前抬起与脊柱间形成一个三角形的间隙。结论 :低场 MRI对腹主动脉瘤诊断、指导治疗和判断预后具有重要作用更多还原

【Abstract】 Purpose To study the diagnostic value of low field MRI on abdominal aorta aneurysm. Materials and Methods 15 patients with abdominal aneurysm were examined with low field MRI. Results 5 aneurysms were superior to the renal artery and 10 aneurysms were inferior to the renal artery. The lenth of aneurysm was 5.1~25 cm [mean (10.8±4.1) cm], the width of aneurysm were 3.6~4.9 cm [mean (5.56±1.85)cm], 5 patients′ renal artery can be seen very clear by MRI, 1 patient′s right renal artery and 4 patient′s common iliac artery were affected. The mural thrombosis of abdominal aneurysm can be found in all patients. MRI didn′t find the calcification on the aneurysm wall and the mural thromboses. The triangle between the aneurysm and the spine aneurysm and the spinal column can be seen in 7 patients. Conclusion The low field MRI have important value in diagnosing, instructing therapy and judging prognosis on abdominal aneurysm.更多还原
