磁共振是原发性颅内淋巴瘤的重要检查方法,在早期发现、准确分期、疗效监测方面具有重要作用。目前弥散加权成像、灌注成像以及磁共振波谱等新的磁共振技术逐渐应用于诊断原发性颅内淋巴瘤。本文介绍对颅内原发性淋巴瘤的临床特点、影像学诊断和鉴别诊断的研究进展以及MR在诊断中的应用。 Magnetic resonance imaging is an important method for the examination of primary intracranial lymphomas and plays an important role in early detection, accurate staging, and efficacy monitoring. New magnetic resonance techniques such as diffusion-weighted imaging, perfusion imaging, and magnetic resonance spectroscopy are increasingly being used to diagnose primary intracranial lymphomas. This article describes the clinical features, imaging diagnosis and differential diagnosis of primary intracranial lymphoma and the application of MR in the diagnosis.
