This article offers an examination of imaging techniques used to diagnose central nervous system (CNS) autoimmune, paraneoplastic, and neuro-rheumatological conditions. An approach to decipher imaging findings in this context is described, encompassing the development of a differential diagnosis from specific imaging patterns and the selection of further imaging for targeted diseases.
Recent breakthroughs in recognizing neuronal and glial autoantibodies have significantly advanced autoimmune neurology, elucidating the imaging hallmarks of certain antibody-associated neurological disorders. Nevertheless, a definitive biomarker remains elusive for many CNS inflammatory diseases. Clinicians ought to identify neuroimaging markers suggestive of inflammatory disorders, and simultaneously appreciate the limitations inherent in neuroimaging. Autoimmune, paraneoplastic, and neuro-rheumatologic disorders often necessitate evaluation with CT, MRI, and positron emission tomography (PET) techniques for accurate diagnosis. Conventional angiography and ultrasonography are potentially valuable additional imaging tools for in-depth evaluation in certain selected scenarios.
Rapid identification of central nervous system (CNS) inflammatory diseases hinges critically on a thorough understanding of both structural and functional imaging modalities, potentially mitigating the need for invasive procedures like brain biopsy in appropriate clinical contexts. internet of medical things 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.
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. Early treatment of central nervous system inflammatory diseases, facilitated by the recognition of suggestive imaging patterns, can minimize morbidity and long-term disability.
In the world, neurodegenerative diseases are a major concern for public health, marked by substantial morbidity and considerable social and economic hardship. This review assesses the effectiveness of neuroimaging as a biomarker for diagnosing and detecting neurodegenerative diseases like Alzheimer's, vascular cognitive impairment, Lewy body dementia/Parkinson's disease dementia, frontotemporal lobar degeneration spectrum disorders, and prion-related diseases, considering their differing rates of progression. Studies employing MRI, metabolic imaging, and molecular imaging techniques (such as PET and SPECT) are briefly reviewed for their insights into these diseases.
Neurodegenerative disorders exhibit distinct brain atrophy and hypometabolism patterns detectable via MRI and PET neuroimaging, facilitating differential diagnosis.

Due to a lack of definitive, direct, and verifiable markers of intracellular misfolded alpha-synuclein, Parkinson's disease continues to be identified through clinical assessment. Given their lack of specificity and inability to reflect nigral pathology, PET- or SPECT-based striatal measures presently have constrained clinical application in moderate to severe Parkinson's Disease. These scans could present superior sensitivity in detecting nigrostriatal deficiency, frequently associated with multiple parkinsonian syndromes, compared to clinical examination. Their potential for identifying prodromal PD in the future might persist, contingent on the development of disease-modifying therapies. To understand the underlying nigral pathology and its functional ramifications, multimodal imaging could hold the key to future advances in the field.
Parkinson's Disease (PD) diagnosis remains reliant on clinical criteria in the absence of precise, direct, and measurable indicators of intracellular misfolded alpha-synuclein. Striatal measures derived from PET or SPECT technology presently show limited clinical efficacy, due to their lack of specificity and the failure to accurately capture the impact of nigral pathology, specifically in patients experiencing moderate to severe Parkinson's disease.
