Central nervous system (CNS) autoimmune, paraneoplastic, and neuro-rheumatologic disorders are analyzed through their imaging, as detailed in this overview. A systematic approach is presented for understanding imaging findings within this scenario, leading to a differential diagnosis based on imaging characteristics, and the selection of additional imaging for specific diseases.
Recent advancements in recognizing neuronal and glial autoantibodies have profoundly impacted the field of autoimmune neurology, clarifying the imaging characteristics associated with certain antibody-driven pathologies. A definitive biomarker for many CNS inflammatory diseases, however, is still elusive. To ensure appropriate diagnoses, clinicians must pay close attention to neuroimaging patterns suggestive of inflammatory conditions, while acknowledging its limitations. Positron emission tomography (PET) imaging, along with CT and MRI, is integral to the diagnosis of autoimmune, paraneoplastic, and neuro-rheumatologic disorders. For enhanced evaluation in particular situations, supplemental imaging procedures, including conventional angiography and ultrasonography, can prove beneficial.
A fundamental ability to utilize structural and functional imaging approaches is crucial for prompt identification of CNS inflammatory diseases, potentially leading to less reliance on invasive procedures such as brain biopsies in suitable clinical scenarios. endocrine genetics The recognition of imaging patterns suggestive of central nervous system inflammatory conditions can facilitate the early application of suitable treatments, leading to a decrease in morbidity and a lower likelihood of future impairment.
Mastering structural and functional imaging techniques is essential for the swift diagnosis of CNS inflammatory conditions, minimizing the need for potentially invasive procedures such as brain biopsies in appropriate clinical circumstances. Imaging patterns indicative of central nervous system inflammatory conditions can also support the early implementation of effective treatments, thereby decreasing morbidity and potential future impairment.
Neurodegenerative diseases are a pressing global health concern, characterized by high levels of morbidity and significant social and economic burdens. This review explores the current state of neuroimaging measures as diagnostic and detection tools for neurodegenerative diseases, including Alzheimer's disease, vascular cognitive impairment, Lewy body dementia/Parkinson's disease dementia, frontotemporal lobar degeneration spectrum, and prion-related diseases, across both slow and rapid progression. Findings from MRI and metabolic/molecular imaging studies (e.g., PET and SPECT) of these diseases are concisely examined.
Neurodegenerative disorders present unique patterns of brain atrophy and hypometabolism visible through MRI and PET neuroimaging, thereby facilitating differential diagnoses.

The integrity of nigral dopaminergic neurons can be directly evaluated via iron-sensitive MRI sequences and neuromelanin-sensitive MRI, potentially offering a reflection of Parkinson's disease (PD) pathology and progression across its complete range of severity. Tauroursodeoxycholic mouse Radiotracer uptake in striatal axons, presently assessed using clinically approved PET or SPECT imaging, mirrors nigral pathology and disease severity specifically in the early phases of Parkinson's disease. A significant advancement in diagnostics, cholinergic PET uses radiotracers targeting the presynaptic vesicular acetylcholine transporter, potentially offering critical insights into the pathophysiology of conditions including dementia, freezing, and falls.
A clinical diagnosis of Parkinson's disease is required because dependable, immediate, and unbiased markers for intracellular misfolded alpha-synuclein are presently absent. The clinical effectiveness of PET or SPECT-based striatal measurements is currently hindered by their lack of precision and inability to visualize nigral damage in those with moderate to advanced Parkinson's disease. These scans could potentially demonstrate greater sensitivity to nigrostriatal deficiency, a feature impacting multiple parkinsonian syndromes, compared to standard clinical examinations. Future clinical use for detecting prodromal Parkinson's disease (PD) might be justified if and when disease-modifying therapies become accessible. Evaluating underlying nigral pathology and its functional consequences through multimodal imaging may be crucial for future advancements.
The diagnosis of Parkinson's Disease (PD) currently depends on clinical assessment, given the absence of unambiguous, direct, and measurable markers for intracellular misfolded alpha-synuclein. Striatal measures obtained via PET or SPECT scans presently exhibit limited clinical utility due to their lack of precision in discerning nigral pathology, a critical issue particularly in individuals with moderate to severe Parkinson's Disease. These scans are potentially more sensitive to nigrostriatal deficiency, a condition that appears in various parkinsonian syndromes, compared to clinical examinations, and they might be recommended for identifying prodromal Parkinson's disease, if and when treatments that modify the progression of the disease become available.
