目前对肌肉骨骼肿瘤进行术前分期及术中切口水平的确定均用MRI检查。新的保留肢体外科技术要求了解肿瘤在骨内纵行侵犯范围,并要明确是否有骨干或骨骺部受侵。T_1WI冠状和矢状象可清楚显示骺软骨板和肿瘤的相互关系。当T_1WI与病理结果矛盾时,T_2WI和STIR结果会有所帮助。增强MRI在对骨肉瘤患者的化疗效果评估方面现已取得进展。作者对骺软骨板闭合前的22例原发于干骺端的恶性骨肿瘤进行平片和MRI检查,以确定肿瘤在长管状骨骨干或骨骺部的侵犯范围并与病理检查相
Current muscle musculoskeletal staging and intraoperative incision level are determined by MRI examination. The new technique of preserving limb surgery requires knowledge of the extent of tumor invasion in the longitudinal bone and the need to see if there is any invasion of the backbone or epiphyseal part. T_1WI coronal and sagittal images can clearly show the epiphysis cartilage and tumor correlation. T-2WI and STIR results may be helpful when T-1WI is contradictory to pathologic findings. Enhanced MRI has made progress in the evaluation of chemotherapy in osteosarcoma patients. The author of the epiphyseal cartilage plate before closure of 22 cases of primary metaphyseal malignant bone tumor plain film and MRI examination to determine the tumor in the long tubular bone or epiphyseal area of the violation and with the pathological phase
