Susceptibility weighted imaging (SWI) has been broadly incorporated to MR protocols as it provides unique additional diagnostic information in a wide variety of neurological conditions. SWI exploits local field inhomogeneities created by various paramagnetics (deoxyhaemoglobin, blood breakdown products), diamagnetics (calcium) or oxygenated blood, hereby provides contrast based on magnetic susceptibility. In this review we present various examples from everyday clinical practice including, among others, acute stroke, neurodegenerative disorders, haemorrhagic lesions, vascular malformations, mycotic intracranial aneurysm, primary central nervous system vasculitis, neoplasms in which SWI was essential for diagnosis. The strongest indications for SWI applications are the neurodegenerative and neuro-vascular diseases, therefore this review is aimed at a wide range of clinicians, mainly neurologists, neurosurgeons and radiologists.
磁敏感加权成像（SWI）已广泛纳入磁共振成像（MRI）协议，因为它在多种神经疾病中提供了独特的额外诊断信息。SWI 利用由各种顺磁性物质（脱氧血红蛋白、血液分解产物）、抗磁性物质（钙）或含氧血液产生的局部磁场不均匀性，从而提供基于磁化率的对比。在本综述中，我们展示了日常临床实践中的各种例子，包括急性卒中等神经退行性疾病、出血性病变、血管畸形、霉菌性颅内动脉瘤、原发性中枢神经系统血管炎、肿瘤等，其中 SWI 对诊断至关重要。SWI 应用的最强适应症是神经退行性和神经血管疾病，因此本综述面向广泛的临床医生，主要是神经科医生、神经外科医生和放射科医生。
