Clinical usefulness of magnetic resonance imaging in multiple system atrophy.
OBJECTIVES To determine the sensitivity, specificity, and positive predictive values of a selection of abnormal findings in the putamen and infratentorial structures on routine magnetic resonance imaging for distinguishing between multiple system atrophy, idiopathic Parkinson's disease, and age matched controls. PATIENTS AND METHODS Two neuroradiologists blindly and independently rated axial ...
متن کاملBrain magnetic resonance imaging in multiple-system atrophy and Parkinson disease: a diagnostic algorithm.
BACKGROUND Brain magnetic resonance (MR) imaging offers the potential for objective criteria in the differential diagnosis of multiple system atrophy with predominant parkinsonism (MSA-P) and Parkinson disease (PD), since it frequently shows characteristic abnormalities in patients with MSA-P and is believed to be normal in patients with PD. OBJECTIVE To determine concordance between clinical...
متن کاملClinical and magnetic resonance imaging study of extrapyramidal symptoms in multiple system atrophy.
Slit-hyperintensity in the outer margin of the putamen on T2 weighted MRI was found in 17 out of 28 patients with clinically diagnosed multiple system atrophy. Thirteen of these 17 patients showed extrapyramidal signs. Five patients had only unilateral slit-hyperintensity; four of them had contralateral rigidity; and one had bradykinesia. Despite mild rigidity, one case showed no slit-hyperinte...
متن کاملDysphagia in Multiple System Atrophy of Cerebellar and Parkinsonian Types
Objective: This study aimed to examine the relationship between dysphagia and activities of daily living (ADL) in patients with multiple system atrophy (MSA), and to characterize dysphagia in patients with the cerebellar (MSA-C) and parkinsonian (MSA-P) types. Methods: Sixty-one MSA patients (25 males, 36 females; 40 MSA-C, 21 MSA-P; mean age, 66.3 ± 11.0) were recruited. ADL was assessed on th...
