【摘要】 本文对2DE(二维切面超声)诊断的27例纵隔肿瘤并经手术及病理对照、分析认为2DE 能够显示纵隔病变,并能准确地提供肿瘤与周围脏器的关系。2DE 对本组27例纵隔肿瘤的位置和物理性质判断与手术后对照,囊性肿物符合率为100%,实质性肿物符合率为80.9%,混合性肿物符合率为100%,定位诊断符合率为81.4%。根据肿瘤的形态,边缘及内部回声可推断其良恶性。更多还原

【Abstract】 Mediastinal tumors of 27 cases diagnosed by Ultrasound images were compared with findings in operation and pathology.It is thought that Ultrasound images can reveal mediastinal lesions and their relationswith surrounding organs precisely.Locations of tumors and their physical natures determined by Ultrasonography were compared to postoperative findings.Core(?)tness for cyst tumor was 100%,for parenchymal tumors 80.9%,for mixed tumors 100%,for locations 81.4%.Benign and malignant tumors could be inferred by their shapes,margins,and internal echoes.更多还原
