Worldwide, Parkinson's disease (PD; primary Parkinsonism) is ahead of other neurological disorders in terms of the growth rate of disability and mortality. Despite significant progress in the study of the etiopathogenesis of PD, early diagnosis is a difficult clinical task. The long latent phase of the disease and the absence of reliable laboratory markers often cause a delay in diagnostic neuroimaging, which, together with the potential unwillingness of the radiologist to see changes characteristic of the neurodegenerative process, leads to untimely diagnosis and, as a consequence, a delay in the appointment of therapy. This article provides a literary review of generally recognized visualization patterns of the disease in accordance with modern concepts, and also discusses the issues of differential diagnosis of PD with the most common Parkinsonism-plus syndromes. A clinical case of the diagnosis of Parkinson's disease in a 93-year-old patient by structural magnetic resonance imaging is presented.
