A research team investigated the case of a male Asian small-clawed otter that fell down the stairs while sleeping, after which it developed left-sided paralysis.

左侧卵巢可见一类圆形囊实性异常信号影，边界光整，病灶内可见多个低信号分隔影，将病灶分成多个囊腔，病灶大小约63mmx51mmx42mm，实性部分大小约37mmx22mmx37mm，信号不均匀，实性部分T1WI及T2WI均呈高低混杂信号，其内可见一直径约11mm的结节状高信号，T2压脂呈 ...

With the patients lying in a supine position on their back with the face up, MRI scans with the following sequences were captured: axial T1-weighted imaging (T1WI) [repetition time (TR) = 139 ms, echo ...

为解决前列腺癌 FSE T2WI 检查运动伪影问题，研究人员开展相关研究，发现膀胱和直肠面积是风险因素。 在前列腺癌的诊断中，使用快速自旋回波（FSE）T2 加权成像（T2WI）技术时会受到运动伪影（T2-MA）的影响。为探究与 T2-MA 相关的风险因素，研究人员回顾性 ...

MRI 是评估直肠癌肿瘤特征和潜在生物学行为的关键影像学工具。标准的直肠 MRI 包括高分辨率 T2 加权成像（High-resolution T2-weighted imaging，HR-T2WI）和扩散加权成像（Diffusion-weighted imaging，DWI）。HR-T2WI 能有效显示肿瘤浸润深度，DWI 有助于区分肿瘤与非肿瘤组织。
