Sangeet Ghai, MD, FRCR
Dr. Sangeet Ghai is the Director of Research (JDMI) and Associate Professor in the Joint Department of Medical Imaging (JDMI) University of Toronto, Canada. He is a Clinician Scientist at Princess Margaret Cancer Centre and also the Director of Prostate Center (Princess Margaret Cancer Centre) and Biopsy Center (TGH). He completed his postgraduate training in India, with a dual fellowship in abdominal imaging and interventional radiology at UofT.
Dr. Ghai works with MRI for diagnostic and intervention purposes, with an active involvement in clinical trials testing new devices and treatments for cancer, with a focus on genito-urinary and prostate disease sites. He is working on MR guided high-intensity focused ultrasound (HIFU), MR guided focal laser ablation and photo-dynamic therapy (PDT) for prostate cancer treatment. As the lead in the development of procedural elements of both MR guided interstitial laser thermal therapy (MRgFLA) and MR guided focused ultrasound ablation (MRgFUS) studies of localized prostate cancer, he has been instrumental in optimizing protocols and treatment delivery techniques for focal therapy under MRI guidance. In addition, he is working to use novel methods to track temperature changes in ablation therapies, including novel MR sequences and diffuse optical thermal mapping, which will help with the accurate and guided delivery of therapy to tumours.
The use of ultrasound for guided interventions and screening is also an interest of Dr. Ghai’s, including performance of high-resolution ultrasound for prostate cancer screening and detection. He is also the imaging lead for a prospective observational study on active surveillance for papillary thyroid cancers.
