Training & Education

The Department of Vascular and Interventional Radiology (DVIR) at Singapore General Hospital (SGH) provides a comprehensive range of vascular and non-vascular interventional service. SGH is a 1600 bed acute tertiary hospital, providing cutting edge medical treatment in all spheres.

The Department has access to 8 interventional radiology suites housed under the Division of Radiological Sciences, which are equipped with state of the art machines including the Siemens Artiz Zeego, Siemens and Toshiba DSA with cone beam CT systems, Toshiba hybrid angio-CT systems and Toshiba biplane systems. All IR suites are equipped with Ultrasound scanners for US guided/assisted interventions. DVIR is staffed by 16 Interventional Radiologists and performs about 10,000 vascular and non-vascular procedures a year.

The spectrum of VIR procedures performed include:

  • Venous access (PICC, tunneled and non tunneled central catheters, ports)
  • Image guided biopsies (including transjugular liver biopsy) and drainages 
  • Dialysis access / central venous angioplasty, stenting, thrombolysis
  • Lower limb angioplasty/stenting (including subintimal and infrapopliteal angioplasty, SAFARI technique), thrombolysis and debulking procedures
  • Aortic stent grafts for aneurysmal disease and dissection
  • DVT thrombolysis and venous stenting
  • IVC filter insertion and removal
  • Embolisation for trauma, tumour, bleeding GIT, PPH, hemoptysis
  • Testicular vein embolization
  • Prostatic artery embolization
  • Fallopian tube recanalization
  • Uterine fibroid embolisation
  • Transarterial Chemo-embolisation (conventional TACE, balloon TACE, drug eluting bead TACE) and radio-embolisation (Y90 spheres)
  • Thermal ablation (RFA; MWA) of liver and lung tumours, as well as benign thyroid nodules
  • Cryoablation of renal and bone tumors
  • Vertebroplasty / cementoplasty for augmentation of musculoskeletal tumours
  • Biliary drainages, dilatations and stenting
  • Nephrostomies and ureteric stenting
  • Radiological guided gastrostomy insertion, NJ tube insertion and GI stenting
  • Fusion and contrast enhanced US guided procedures

DVIR Medical Students Electives

DVIR welcomes elective medical students throughout the year. This is an opportunity to experience the many ways interventional radiology impacts upon patient care across many specialties.

Aims of DVIR medical student electives: 

  • Learn how and when various imaging modalities (ultrasound, fluoroscopy, CT) are used to guide procedures 
  • Be familiar with the indications, techniques and potential complications of the following common IR procedures:
  • Vascular: central venous access, percutaneous angioplasty and stenting
  • Non vascular: biopsies, drainages, percutaneous nephrostomy and biliary drainage
  • Oncological:  tumour ablation, radio-embolisation, chemoembolization
  • Learn how patients are prepared for IR procedures and if they are indicated, safe and feasible
  • Learn radiation protection methods used during fluoroscopic and CT interventions
  • Opportunity to assist in patient workup, rounds, consent taking and procedures

Types of medical student electives at DVIR

  • Clinical elective 
  • Clinical plus research elective
  • Research elective 

Electives can either be standalone (i.e. DVIR alone) or in combination with concurrent electives in the Department of Diagnostic Radiology (DDR) and/or Department of Nuclear Medicine and Molecular imaging (DNMMI).

How to apply

Local medical school students (e.g. Yong Loo Lin School of Medicine, Duke-NUS medical school and Lee Kong Chian School of Medicine) should apply via their respective internal medical school application process for electives. 
Overseas medical students can find more information on how to apply at the SGH Associate Dean’s Office website.
