脑静脉血栓形成是一种相对罕见但严重的神经系统疾病，通过及时诊断和适当的医疗护理可能是可逆的。由于这种疾病的可能的病因和临床表现是多种多样的，成像在诊断中起着主要作用。磁共振（MR）成像、非增强计算机断层扫描（CT）、非增强飞行时间MR静脉造影和造影剂增强MR静脉造影和CT静脉造影是检测可能与血栓形成相关的脑静脉和脑实质变化的特别有用的技术。为了获得准确的诊断，重要的是要详细了解正常静脉解剖结构和变异，发现的范围（静脉窦血栓和再通，实质扩散或灌注变化或出血），其他潜在的相关条件（深静脉闭塞，孤立的皮质静脉血栓形成，特发性颅内高压），以及图像解释中的潜在陷阱。
Cerebral venous thrombosis is a relatively uncommon but serious neurologic disorder that is potentially reversible with prompt diagnosis and appropriate medical care. Because the possible causal factors and clinical manifestations of this disorder are many and varied, imaging plays a primary role in the diagnosis. Magnetic resonance (MR) imaging, unenhanced computed tomography (CT), unenhanced time-of-flight MR venography, and contrast material - enhanced MR venography and CT venography are particularly useful techniques for detecting cerebral venous and brain parenchymal changes that may be related to thrombosis. To achieve an accurate diagnosis, it is important to have a detailed knowledge of the normal venous anatomy and variants, the spectrum of findings ( venous sinus thrombi and recanalization, parenchymal diffusion or perfusion changes or hemorrhage), other potentially relevant conditions ( deep venous occlusion, isolated cortical venous thrombosis, idiopathic intracranial hypertension), and potential pitfalls in image interpretation.
