OsiriX™ is a Digital Imaging and Communications in Medicine (DICOM) viewer with an intuitive user interface that has been widely used by radiologists and other specialists in their daily practice. OBJECTIVE: To describe OsiriX™, a tool for in office manual measurement of hippocampal volume. METHODS: The open-source OsiriX™ viewer was used with three dimensions (3D) T1 weighted spoiled gradient recalled echo (SPGR) sequence images, with 1 mm slice thickness and 0.1mm gap (voxel size 1 mm3 ). Magnetic Resonance Imagings (MRI) were obtained on a 1.5 T system. The entire procedure lasted less than 15 minutes for each hippocampus. CONCLUSION: OsiriX™ viewer is a feasible tool for in office manual hippocampal measurement. There is no standard hippocampal volume for Alzheimer’s disease, thus comparison could be regarded as the rate of hippocampal atrophy over time, correlated with clinical evaluation and cognitive tests. 2016 artículo científico 2447-2115 https://www.redalyc.org/articulo.oa?id=739780694006 en http://www.redalyc.org/revista.oa?id=7397 Geriatrics, Gerontology and Aging application/pdf Sociedade Brasileira de Geriatria e Gerontologia Geriatrics, Gerontology and Aging (Brasil) Num.1 Vol.10 |
