Abundance of salt-alkaline megatherm Classopollis-Ephedripites assemblage in a limited time illustrates a short duration of dry hot climate by latest Cretaceous.

Other factors, such as asteroid impact and large volcanic eruption triggering global mass extinction caused the regional climate change.

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

结果：大部分滑膜肉瘤位于关节旁；X线表现为圆形、椭圆形或分叶状软组织肿块，部分可见肿块内钙化；典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块；磁共振T1WI与肌肉信号相比，滑膜肉瘤表现为分叶状、不均匀、等或稍高信号，T2WI则表现为高信号为主的不均匀信号；DSA呈显著的肿瘤实体染色及新生血管。
