Care at NUH

Department of Diagnostic Imaging Fellowship Programme


National University Hospital (NUH) is a tertiary academic hospital with over 1,200 beds. It is a major referral centre which offers a comprehensive range of medical and surgical specialties in Southeast Asia, at the forefront of cutting-edge medicine. It delivers services such as organ transplantation, paediatric surgery (including highly specialised paediatric cardiac surgery), oncology, various cardiovascular and neurological therapies (surgical, medical and neurointerventional). Subspecialised paediatrics and obstetrics and gynaecology departments are also under the same roof. Moreover, we are one of the three comprehensive stroke centres in Singapore, leading acute ischemic stroke thrombolysis and thrombectomy programmes in this part of the world.

The Department of Diagnostic Imaging (DDI) provides high quality imaging and therapeutic (interventional and nuclear medicine) services to the clinical specialties at NUH, by a team of more than 50 specialist radiologists in pursuit of clinical, research and educational excellence. On average, we perform approximately 150,000 studies each year and this includes more than 6,000 interventional radiological procedures (including approximately 500 therapeutic neurointerventions); 3,200 PET/CT studies; 30,500 MRI and 57,000 CT studies; 30,600 ultrasound examinations and 8,900 mammograms.

We are equipped with a vast array of advanced machinery viz, 3 angiography suites (1 biplane DSA machine, 1 hybrid CT-Angio suite, 1 single plane DSA unit); 10 MRI scanners, 2 PET-CT scanners, 1 SPECT–CT, 2 gamma cameras, 6 CT scanners (2 are dual energy CT scanners, 4 are dual source / dual energy CT scanners) ), 3 mammography units (1 machine is a tomosynthesis machine and 2 are contrast enhanced mammography enabled) and multiple ultrasound machines. We also have a PET-MRI scanner for research purposes within the University campus.

We offer fellowship programmes in following services:

  1. Body Imaging
  2. Breast Imaging
  3. General Radiology
  4. Interventional Radiology
  5. Advanced Interventional Radiology in Neurointervention
  6. Musculoskeletal Imaging
  7. Neuroradiology
  8. Nuclear Medicine
  9. Paediatric Radiology

All Radiology fellowships consist of 6 or 12 months of rigorous training with multimodality exposure to your subspecialty area of interest. Depending on their abilities and interests, fellows may be involved in resident and medical student teaching, multidisciplinary rounds and research projects. Fellowships are designed to prepare individuals for an academic career or practice within a subspecialty.

Fellows are expected to read various imaging studies, protocol and supervise or perform procedures under supervision. There is an expectation that weekend work may occur. In this case, the fellow will be compensated with off in lieu time during the week. On call work may also be required, depending on the subspeciality fellowship programme one chooses.

Our department attracts enthusiastic collegial fellows interested in expanding their subspecialty knowledge through evidence-based medicine. The fellowship training program intake will take place twice a year, in January and July. Please submit your application at least 18 months before your preferred attachment date.


To be eligible, applicants must:

  1. Have a post-graduate medical degree from a recognised institution in their country of study.
  2. Have a full radiology qualification (local equivalent of FRCR, FRANZCR, FRCPC or American Board of Radiology), from the appropriate accreditation body in their country.
  3. Have at least 5 years of experience working in a radiology department.
  4. Be proficient in English. English proficiency exams like TOEFL and IEPLT are a pre-requisite for registration with the Singapore Medical Council if the applicant's medical education was not conducted in English (please refer to the Singapore Medical Council website for further details).

Body Imaging Fellowship

Body Imaging Fellowship offers in-depth training in cardiac, chest, abdominal and pelvic radiology. One of the fortes of our body imaging fellowship programmes is the scope of learning transplant related imaging (for e.g. liver transplantation) as well as advanced CT and MRI cardiac imaging as we service the National University Heart Centre. We also perform several other advanced body imaging studies such as multiphasic MRI for the liver and multiparameteric MRI imaging of the prostate, MRI enterography, CT colonography and enterography and dual energy CT pulmonary angiogram studies.

Breast Imaging Fellowship

Apart from training in the interpretation of imaging studies and interventional procedures, the Breast Imaging Fellowship also places emphasis on the development of multidisciplinary breast practice and a good understanding of the current status of breast diagnosis and management. This includes comprehensive breast imaging, breast cancer genetics, breast cancer surgery, breast pathology and breast cancer oncology. Our fellows can expect to achieve proficiency in advanced breast imaging such as MRI breast, breast tomosynthesis and contrast enhanced mammography at the completion of their fellowship.

General Radiology Fellowship

The General Radiology Fellowship provides and overall exposure to various aspects of radiology. It includes training in the interpretation & reporting of plain films in both routine & emergency settings, fluoroscopy, general ultrasound, CT and MRI. A reasonably good exposure to cross sectional imaging will be available to fellows undergoing this programme.

Interventional Radiology

The comprehensive interventional radiology services at NUH is a perfect training ground for anyone with passion of obtaining proficiency in this exciting field of therapeutic radiology. We have a very strong hepatobiliary interventional service that includes Y90 radio-embolisation therapy for liver tumors, TIPS, Transjugular liver biopsy and liver transplant related interventions. We provide a 24/7 endovascular treatment in acute ischaemic stroke service and over 100 stroke thrombectomies a year. A variety of other complex neurointerventional treatments such as flow diversion, AVM and AVM embolization, intra-arterial chemosurgery for retinoblastomas are performed regularly at our department.

We organise workshops on stroke and aneurysm treatment from time to time and fellows are encouraged to attend. In the field of interventional oncology, besides biopsies of most regions in the body we also perform thermal ablation therapies for different organ systems. We work in close collaboration with our vascular surgeons for aortic interventions. Besides the aforementioned niche areas, we are a high-volume centre for routine IR procedures such as embolization for bleeders and tumours, biliary drainage and stenting, nephrostomy insertion and ureteric stenting, dialysis access related interventions, peripheral vascular interventions and drainages.

Advanced Interventional Radiology in Neurointervention

NUH as a world-renowned academic healthcare centre of excellence also harbours a world-class neurointerventional service. We perform an approximately of 500 therapeutic Neurointerventions each year, excluding several diagnostic neurointerventional procedures. The general scope of services includes treatment of cerebral aneurysms (coiling, flow diversion, intrasaccular flow disruption), cerebral and spinal AVM and AVF embolisations (including reconstructive therapies for DAVF), acute stroke thrombectomy, endovascular management of intra and extracranial atherosclerotic disease, IAC for paediatric retinoblastomas, pre-operative embolisation for head and neck as well as spinal tumours, embolisation for head and neck bleeders and percutaneous treatments for vascular malformations, as well as spinal pain therapies. Neurointervention in NUH is helmed by a highly experienced team of three senior consultants viz A/Prof (Adj) Anil Gopinathan, Dr Yang Cunli and Dr Leonard Yeo. Besides the high volume of clinical work, we are also active in clinical research and international clinical trials. In the last five years, more than 100 research papers have come from our team and we also have a large number of invited lectures and scientific papery presented by our faculty members.
