The thalami are bilateral ovoid grey matter cerebral structures bordering the third ventricle on both sides, which participate in functions such as relaying of sensory and motor signals, regulation of consciousness, and alertness. Pathologies affecting the thalami can be of neoplastic, infectious, vascular, toxic, metabolic, or congenital origin.The purpose of this review is to provide a comprehensive approach to the thalamus focusing on its anatomy, the main pathologies affecting this structure and their radiological semiology on CT and MRI. We will also illustrate the importance of multimodal MR imaging (morphologic sequences, diffusion-weighted imaging, perfusion, spectroscopy) for the diagnosis and treatment of these conditions.
丘脑是双侧的卵圆形灰质脑结构，两侧与第三脑室相邻，参与感觉和运动信号的传递、意识调节及警觉等功能。影响丘脑的病变可能源于肿瘤、感染、血管、中毒、代谢或先天性因素。本综述的目的是提供一种全面探讨丘脑的方法，重点关注其解剖结构、影响该结构的主要病变及其在CT和MRI上的放射学征象。我们还将阐述多模态磁共振成像（形态学序列、扩散加权成像、灌注成像、波谱分析）在这些疾病诊断和治疗中的重要性。
