Diffusion Tensor Imaging and Fractional Anisotropy

Dr Rahul P Kotian is currently working as an Assistant Professor in the medical imaging sciences program of College of Health Sciences, Gulf Medical University, Ajman, the United Arab Emirates from September 2021 and has a teaching and research experience of 13 years in the field of medical imaging. Dr Rahul served at Manipal College of Health Professions, Manipal Academy of Higher Education,Manipal, Karnataka, India for over a decade in different capacities from 2009 to 2019. He was the former Dean and Professor at the College of Allied Health Sciences, NIMS University, Jaipur, Rajasthan.Dr Rahul was also the Associate Dean at the College of Allied Health Sciences, Srinivas University, Mukka, Mangalore, Karnataka, India.He was also the Radiation Safety Officer Level I at Kasturba Medical College and Hospital, Manipal Academy of Higher Education(2011-2014, 2014-2017 and 2017-2019).  Dr Rahul is a doctorate in magnetic resonance imaging and received his PhD fromManipal College of Health Professions, Manipal Academy of Higher Education, Manipal, Karnataka, India.He was the first clinical PhD in magnetic resonance imaging and Parkinson’s disease in medical imaging in India.Dr Rahul was recognized with honorary doctorate for his excellence in the field of medical imaging technologyin 2021 from Bharat Virtual University for Peace and Education (Unit of United Nations Organization, Geneva).  Dr Rahul has published several scientific research papers in the field of radiology and magnetic resonance imaging (MRI), diffusion tensor imaging(DTI), fractional anisotropy(FA), Parkinson’s disease (PD), computed tomography(CT) and radiation protection. He is a reviewer for many Scopus indexed peer-reviewed journals.He is recognized internationally and nationally as a leader in the field of medical imaging in DTI and FA imaging and has presented several research papers. He is also one of the keynote and guest speakers at various international and national conferences. 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.
