• Since it’s approval in 2012, 123I Ioflupane is widely used in the United States to aid the evaluation of patients with suspected Parkinson’s disease.   • Nuclear medicine practitioners interpreting these studies most commonly use visual qualitative analysis to determine if a study is normal of abnormal.   • Difficult to interpret cases are not uncommon, in certain cases, quantitative evaluation with the putamen/caudate/background ratios are useful. • A collection of cases from our Database will be presented with a literature supported approach. After viewing this exhibit the learner will become familiar with the different aspects fo DatScan imaging and will be exposed to a number of cases to enrich his/her experience for interpretation in clinical practice.  

• Principles of DatScan imaging • Imaging protocol of DatScan • Importance of DatScan and its role in the diagnostic process of Parkinson’s Disease and other Parkinsonian Syndromes. • Interpretative approach, other examples: - Normal - Abnormal - Borderline cases - Common artifacts -Non diagnostic cases - Effect of medication in the interpretation of DatScan  examples - Quantitative evaluation tools and their limitations.  examples
