Differential diagnosis of parkinsonism: a metabolic imaging study using pattern analysis

Abstract: Summary Background Idiopathic Parkinson’s disease can present with symptoms similar to those of multiple system atrophy or progressive supranuclear palsy. We aimed to assess whether metabolic brain imaging combined with spatial covariance analysis could accurately discriminate patients with parkinsonism who had different underlying disorders. Methods Between January, 1998, and December, 2006, patients from the New York area who had parkinsonian features but uncertain clinical diagnosis had fluorine-18-label… Show more

“…Derived scores can be used to monitor a patient's status by gauging network progression in longitudinal imaging data, or to evaluate treatment effects. In complex cases of undetermined diagnosis, sets of subject scores can be entered in logistic regression analysis (or in other discriminant function models) to distinguish between different alternatives 12,13 . This approach can be vitally important given the high rate of clinical misdiagnosis in individuals with early disease, and the varying prognosis and treatment outcome associated with the different underlying pathologies.…”

“…Örnek olarak; PH'de beyin FDG PET görüntülemede premotor, suplementer motor ve parietal kortikal bölgelerde metabolizma normale oranla azalmış; pallidotalamik ve pontoserebellar bölgelerde ise artmış olarak izlenir (3,19,33). Buna karşılık, MSA'da bazal gangliada ve serebellumda hipometabolizma izlenir ve bu tutulum farklılığı sayesinde MSA ile PH'nin ayırıcı tanısı yapılabilir (1,21,35,39,41). Beyin FDG PET görüntüleme bulgularına dayanan tanısal sınıflandırma kesin klinik tanı ile %90 oranında örtüşmekte ve nörodejeneratif parkinsonizm nedenleri (PH, MSA, PSP ve LCD) %90 oranında ayırt edilebilmektedir (21,22,35,40).…”

Parkinsonizm sendromlarında beyin FDG PET görüntüleme saptanan anormal bulguların yaygınlığı ve derecesi klinik bulgular ile genellikle korelasyon gösterir (1,3,19,23,24,30,34,35,39,49,50,51,52).…”
