This article details the imaging approaches used in the assessment of central nervous system (CNS) autoimmune, paraneoplastic, and neuro-rheumatologic diseases. This document describes an approach for the interpretation of imaging data in this context, building a differential diagnosis based on specific imaging patterns, and suggesting additional imaging to diagnose particular diseases.
The groundbreaking identification of novel neuronal and glial autoantibodies has dramatically reshaped the landscape of autoimmune neurology, revealing distinctive imaging signatures for specific antibody-mediated diseases. Unfortunately, a definitive biomarker is absent in many cases of CNS inflammatory diseases. Neuroimaging patterns indicative of inflammatory disorders, along with the inherent limitations of imaging, must be recognized by clinicians. Autoimmune, paraneoplastic, and neuro-rheumatologic diseases are diagnosed with a combination of diagnostic imaging techniques, including CT, MRI, and positron emission tomography (PET). In specific circumstances where further evaluation is needed, additional imaging techniques such as conventional angiography and ultrasonography are potentially helpful.
Knowledge of both structural and functional imaging modalities is essential in diagnosing central nervous system (CNS) inflammatory diseases promptly, often minimizing the need for invasive procedures such as brain biopsies in particular clinical settings. this website Recognizing imaging patterns signifying central nervous system inflammatory diseases can also allow for the prompt initiation of the most appropriate treatments, thus reducing the severity of illness and potential future disability.
Accurate and timely diagnosis of central nervous system inflammatory diseases crucially depends on a deep knowledge of both structural and functional imaging modalities, potentially leading to the avoidance of invasive procedures such as brain biopsies in specific cases. Imaging patterns characteristic of central nervous system inflammatory conditions can also facilitate early treatment, minimizing potential long-term complications and future disabilities.

Neurodegenerative diseases are a globally recognized cause of significant health problems, including high morbidity rates and considerable social and economic hardship. Neuroimaging's role as a biomarker for the diagnosis and detection of slowly and rapidly progressive neurodegenerative conditions, including Alzheimer's disease, vascular cognitive impairment, dementia with Lewy bodies or Parkinson's disease dementia, frontotemporal lobar degeneration spectrum disorders, and prion-related diseases, is reviewed here. Briefly, studies leveraging MRI and metabolic/molecular imaging techniques, including PET and SPECT, assess findings related to these diseases.
Neuroimaging studies using MRI and PET have shown varying brain atrophy and hypometabolism patterns across neurodegenerative disorders, contributing substantially to differential diagnostic processes. Advanced MRI methods, including diffusion imaging and functional MRI, yield valuable data about the biological alterations associated with dementia, leading to potential novel clinical assessments. Advancements in molecular imaging, ultimately, permit clinicians and researchers to ascertain the levels of neurotransmitters and dementia-related proteinopathies.
Although symptom evaluation remains a key aspect of diagnosing neurodegenerative diseases, in vivo neuroimaging and the study of liquid biomarkers are revolutionizing clinical diagnosis and intensifying research into these debilitating conditions.

Neuromelanin-sensitive MRI, along with iron-sensitive MRI sequences, can directly assess the viability of nigral dopaminergic neurons, serving as an indicator of Parkinson's disease (PD) pathology and its progression across the full spectrum of disease severity. Biotic surfaces The correlation of striatal presynaptic radiotracer uptake, evaluated via clinical PET or SPECT imaging in terminal axons, with nigral pathology and disease severity is limited to the early manifestation of Parkinson's disease. Radiotracers targeting the presynaptic vesicular acetylcholine transporter are key to cholinergic PET, a substantial advancement, potentially providing invaluable information about the pathophysiology of clinical presentations such as dementia, freezing of gait, and falls.
The absence of clear, direct, and objective biomarkers for intracellular misfolded alpha-synuclein necessitates a clinical diagnosis for Parkinson's disease. Despite their widespread use, PET- or SPECT-based striatal measurements are presently limited clinically, suffering from a lack of specificity and an inability to depict nigral pathology in individuals with moderate to severe 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. Future breakthroughs in the field might arise from using multimodal imaging to investigate the underlying nigral pathology and its functional effects.
The absence of clear, immediate, and quantifiable indicators of intracellular misfolded alpha-synuclein necessitates a clinical diagnosis for Parkinson's Disease. The clinical benefit of using striatal measures from PET or SPECT scans is currently limited by their imprecise nature and inability to fully represent nigral pathology, notably in cases of moderate to severe Parkinson's Disease. The sensitivity of these scans, in detecting nigrostriatal deficiency—a feature of various parkinsonian syndromes—might surpass that of physical examinations.
