Dr Gregory Tarr is an interventional radiologist practising in Brisbane and Ipswich. He studied medicine at the University of Otago, where he also completed a PhD in vascular biology. His subspecialty interventional radiology fellowships were at Auckland City Hospital and at Vancouver General Hospital / University of British Columbia.
He is a Fellow of the Royal Australian and New Zealand College of Radiologists (FRANZCR) and holds the European Board of Interventional Radiology (EBIR). His research spans interventional radiology, interventional oncology, stroke intervention and the use of artificial intelligence in radiology. He also trained extensively in venous and arteriovenous malformation work with Dr Gerald Legiehn (FIRVA) in Vancouver.
Before dedicating himself to private practice, he was a staff specialist interventional radiologist at the Royal Brisbane and Women's Hospital. His clinical practice centres on procedures that offer patients an alternative to open surgery, embolisation for fibroids, adenomyosis, enlarged prostate, varicocele, pelvic venous congestion and musculoskeletal pain, as well as tumour ablation and Y-90 selective internal radiation therapy for liver cancer.
Dr Tarr offers advanced interventional radiology across the whole body, essentially everything from the neck down (the brain and spine aside). Most procedures are carried out under sedation with image-guided regional analgesia, so in many cases a general anaesthetic isn't needed, which can mean a gentler experience and a faster recovery.
Dr Tarr believes patients make the best decisions when they genuinely understand all of their options. Consultations are unhurried and jargon-free. They always cover the alternatives, including surgical and conservative ones, so you can choose what's right for you.
You'll understand your condition, the procedure, the evidence behind it and the realistic outcomes. Before anything is booked.
Embolisation isn't right for everyone. If surgery, medication or watchful waiting would serve you better, that's exactly what Dr Tarr will tell you.
Many procedures are done under sedation with image-guided regional analgesia, often avoiding a general anaesthetic. You recover faster and get back to work, family and normal life sooner.
Dr Tarr's PhD investigated vascular biology, inflammation, vessel remodelling, outcome prediction and clinical biomarkers. He has since published peer-reviewed research across interventional radiology, interventional oncology and stroke intervention, the safety and diagnostic yield of percutaneous biopsy, and the implementation of artificial intelligence in radiology, including work in Stroke and the Journal of Vascular and Interventional Radiology.
