Dr. Santhosh Raj is a Consultant Radiologist with subspecialty in Neuroradiology & Neurointervention at Farrer Park Hospital. He obtained his Fellowship of the Royal College of Radiologists (U.K.) in 2008 and completed the Advanced Specialist Training (AST) in Radiology administered by the Singapore Specialist Accreditation Board. In 2015, Dr. Santhosh was awarded the SingHealth Health Manpower Development Program fellowship and underwent training in neurointervention at the National Institute of Clinical Neurosciences in Budapest, Hungary.

Before private practice, Dr. Santhosh was the Deputy Director of Vascular and Interventional Radiology at Singapore General Hospital (SGH). He was part of the Scientific Advisory Board for the 14th Congress of The World Federation of Interventional and Therapeutic Neuroradiology (WFITN) 2017. He was also the Chair of the 2nd Interventional Neuroradiology Workshop organized by the National Neuroscience Institute, Singapore in 2016. Dr. Santhosh was also co-appointed Adjunct Assistant Professor with DUKE-NUS and Clinical Lecturer with the National University Hospital’s Yong Loo Lin School of Medicine. He is currently Visiting Consultant at Singapore General Hospital (SGH) and KK Women’s and Children’s Hospital (KKH).

In recent years, he has actively devoted his time to the clinical adoption of artificial intelligence, primarily in the field of neuroradiology. He has been an advocate in using Quantitative MRI (qMRI) on the brain using Automated Segmentation to detect early imaging features of neurodegenerative diseases such as dementia, Alzheimer’s disease, epilepsy, and traumatic brain injury. He was previously Vice-Chair, Enterprise Imaging Committee of the Singapore eHealth Innovations Summit 2016.
