上海交通大学医学院附属瑞金医院李彪/张瑞岩/闫小响团队发现[68Ga]Ga-DOTA-FAPI-04 PET/MR在预测急性心梗患者远期左心室不良重构中的潜在价值（图）
心肌梗死 左心室重构 心肌细胞 瑞金医院

急性ST段抬高型心肌梗死（STEMI）后的心力衰竭会引起远期复杂的心脏结构变化，即左心室重构，并可能与不良的预后有关。急性心肌梗死后的心肌纤维化在左心室重塑中起着关键作用。成纤维细胞是这种反应的主要媒介。心梗后活化的成纤维细胞迁移到梗死的心肌中，并产生大量的细胞外基质蛋白，促进受影响组织的修复和维持结构的完整性。尽管最初的死亡心肌细胞替换和纤维化对防止缺血性损伤后心室壁破裂至关重要，但过度心肌纤维...

基于GA与模糊连接的冠状动脉造影图像分割
血管分割 模糊连接 遗传算法 冠状动脉造影
2014/6/10
针对模糊连接图像分割方法在实现上的困难,提出了一种基于遗传算法的模糊连接分割方法。方法 首先把路径强度作为遗传算法的寻优条件,从而得到图像中各点到种子点间的最优路径,其强度即该点的模糊连接度。然后,以各点的模糊连接度作为其灰度值,形成目标和背景不交叉的新图,最后用阈值法把目标物体提取出来。结果 实验结果表明,将该方法应用于冠状动脉造影图像的血管分割,能准确快速地将血管从背景中分割出来。结论 该分割...
