动态增强磁共振成像在评估脊柱肿瘤血供中的应用
Application of dynamic contrast-enhanced magnetic resonance imaging in evaluating the blood supply of spinal tumors
摘要
Abstract
Objective To investigate the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in evaluating the blood supply of spinal tumors.Methods DCE-MRI was performed on 20 patients with spinal tumors before surgery to assess the blood supply of the tumors.The 12 patients with highly vascularized tumors under-went embolization treatment,while 3 patients with highly vascularized tumors and 5 patients of hypovascularized tumors were not adopted with embolization treatment.The blood flow(BF)ratio and surgical conditions were recor-ded.The digital subtraction angiography(DSA)score was recorded in 12 patients who underwent embolization treat-ment.Results Among the 12 patients who were preoperatively diagnosed with highly vascularized tumors and under-went DSA and embolization treatment,both of 3,4 points of DSA scores were in 6 cases,and the BF ratio was 1.84～5.14,the operation time was 200～260 min,the intraoperative blood loss was 1 200～1 600 ml,and the intraopera-tive blood transfusion volume was 800～1 200 ml.For the 3 patients who were preoperatively diagnosed with highly vascularized tumors but did not undergo embolization treatment,the BF ratio was 1.86～4.45,the operation time was 280～350 min.The intraoperative blood loss was 1 700～5 000 ml,and the intraoperative blood transfusion volume was 1 600～3 400 ml.For the 5 patients who were preoperatively diagnosed with hypovascularized tumors,the BF ra-tio was 0.89～1.24,the operation time was 200～220 min,the intraoperative blood loss was 900～1 000 ml,and the intraoperative blood transfusion volume was 400～800 ml.Pearson's product-moment correlation coefficient was used for correlation analysis,showing that the BF ratio was positively correlated with intraoperative blood loss and intraop-erative blood transfusion volume.When the BF ratio was high,the intraoperative blood loss and blood transfusion vol-ume were relatively increased.There was little correlation between the BF ratio and the operation time.Conclusions DCE-MRI has a positive guiding role in preoperative assessment of spinal tumor blood supply,preoperative DCE-MRI examination enables the surgeon to make an prediction of the tumor's blood supply.关键词
