RT Journal Article SR Electronic T1 Distinguishing Primary Lateral Sclerosis from Parkinsonian Syndromes with the Help of Advanced Imaging JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 1318 OP 1319 DO 10.2967/jnumed.121.261942 VO 62 IS 9 A1 Pegah Masrori A1 Donatienne Van Weehaeghe A1 Koen Van Laere A1 Philip Van Damme YR 2021 UL http://jnm.snmjournals.org/content/62/9/1318.abstract AB We describe a unique case of a patient presenting with unilateral mild paresis, slowing of the upper limb, and parkinsonism, who underwent a full imaging work-up including MRI, 123I-FP-CIT PET, 18F-FE-PE2I PET, and 18F-FDG PET. This case demonstrates that imaging may aid substantially in the diagnostic work-up of complex neurologic disorders.
