The targeting accuracy of proton therapy (PT) for moving soft-tissue tumours is expected to greatly improve by real-time magnetic resonance imaging (MRI) guidance. The integration of MRI and PT at the treatment isocenter would offer the opportunity of combining the unparalleled soft-tissue contrast...

2半月板损伤机制及MRI信号产生机制 半月板出现退变或撕裂时,关节腔内滑液经半月板关节面缺口渗入退变或撕裂的半月板,使水分子局限于分界面区域,增加了该区域的质子浓度;半月板内大分子和滑液相互作用使质子的旋转率降低,缩短了T1、T2值,因此T1WI和质子密度加权成像(protondensityweightedimaging,PDWI)对于显示半月板损...
