为进一步明确，遂来本中心检查。 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 ...

In the current study, 202 patients receiving lung cancer surgery were included. Preoperative MRI-T1WI images were collected to train the deep learning signature utilized the ResNet-152 algorithm. The ...

d. Eccentricity index = maximum wall thickness – minimum wall thickness/maximum wall thickness. e. Intraplaque hemorrhage was defined as the T1WI signal in the plaque being ≥150% of the T1WI signal in ...

继发性病变对海绵窦的侵犯，主要为鼻咽癌、侵袭性垂体瘤等症状。鼻咽癌主要通过卵圆孔侵及海绵窦，通常会在鼻咽部观察到原发肿瘤，T1WI呈低信号、T2WI通常是混杂信号，增强扫描具有显著强化现象。常合并蝶窦和颅底骨质破坏症状，颈部淋巴结肿大多见。
