软组织肿瘤是间充质来源的一大类异质性肿瘤,组织学成分复杂、种类繁多。多数为良性肿瘤,软组织肉瘤预后差,复发率高。目前常用的影像学评价方法包括:B超、PET-CT、X线平片、DSA、CT、MRI检查。其中,MRI是目前软组织肿瘤首选的影像学方法。结合MRI及上述影像学检查方法,能够充分显示肿瘤特征及病变侵犯周围组织的范围,对肿瘤进行定位、定性诊断,指导软组织肿瘤的分级、分期,有利于制定临床治疗计划乃至手术方案的选择,为临床有效治疗提供前瞻性的依据。
Soft tissue tumors are a large group of heterogeneous tumors of mesenchymal origin, with a complex histological composition and a large variety of tumors. Most benign tumors, soft tissue sarcoma poor prognosis, high recurrence rate. Currently used imaging evaluation methods include: B-, PET-CT, X-ray, DSA, CT, MRI examination. Among them, MRI is the preferred imaging method for soft tissue tumors. Combined with MRI and the imaging examination method, can fully display the tumor characteristics and lesions surrounding the scope of the surrounding tissue, the tumor localization, qualitative diagnosis, guidance of soft tissue tumor grading, staging, is conducive to the development of clinical treatment plans and even the choice of surgical options, Provide a prospective basis for effective clinical treatment.
