The book covers all aspects of one of the most advanced magnetic resonance imaging techniques, namely Diffusion Tensor Imaging (DTI) and Fractional Anisotropy (FA) values in early Parkinson's disease (PD) patients. It provides step-by-step descriptions of DTI and its use in the early diagnosis of Parkinson's disease by using FA values at several grey and white matter regions of the brain with helpful MRI DTI images. It includes clear flow charts with MRI DTI imaging protocol for Parkinson's disease to aid in early diagnosis and treatment. The book covers essential information on anatomy and pathology in Parkinson's disease and includes dedicated chapters on diffusion tensor imaging and FA in Parkinson's disease. Additionally, it covers the role of magnetic resonance imaging in Parkinson's disease with routine findings for Parkinson's disease in MRI, followed by advanced imaging biomarkers and predictors in Parkinson's disease. The book will assist the practitioners in the early detection of Parkinson's disease using specific imaging biomarkers with the help of FA values, which will help in the early treatment of PD patients and thus extend and improve their quality of life. It will also be relevant for MD radiology, M.Sc. medical imaging technology students/trainees and Ph.D. medical imaging graduates as well as B.Sc MIT students.

Dr Prakashini Koteshwar is a Professor and Head of the department of radiology, Kasturba Medical College (KMC), Manipal Academy of Higher Education, Manipal, Karnataka, India and serving at KMC since 2006. She perused her MD degree in radiodiagnosis and imaging from KMC, Manipal Academy of Higher Education.During her tenure, she initiated different academic programmes and recently commenced the 'interventional division' which is going to provide all high-endsemi-invasive non-surgical options of treatment, for various emergency and non-emergency conditions.

Dr Koteshwar's area of interest is neuroimaging, cardiovascular imaging and interventional radiology. She has completed Level I accreditation in CT and MRI reporting of cardiac imaging. She has been working with AI-based algorithm applications in brain tumours and computational flow dynamics in carotid, and renal arteries and presently on 'the effect of peristalsis on ureteric flow'.She has several publications to her credit both in national and international reputed journals on clinical, radiological and AI aspects. She has been guiding several research and PhD projects for MD radiology, MSc medical imaging students and also engineering graduates.

Dr Koteshwar is an auditor of NABH, ISO accreditation and is in charge of the documents related to MCI recognition for MBBS and MD radiology. She is also currently working with grant projects of DST/SERB and industry collaborations too.
