Teaching Profile


Professor Ann king has been a dedicated teacher in the undergraduate medical curriculum at CUHK for over 20 years, receiving consistently high teaching scores from her students and being a member of many faculty teaching committees. Since 2002 she has been in charge of developing and coordinating the radiology teaching program, an integrated course that spans the curriculum with three core components of (1) Radiology anatomy (Preclinical years); (2) Basic radiology of emergency and common diseases (First clinical year); (3) More advanced system based image interpretation (Final Clinical year). The latter course is a highly regarded one week intensive small group tutorial program for all students that is run eight times a year. Currently the course is being updated to include e-learning on patient preparation and risks, and a short modality rotation which was previously only available to students taking the popular radiology elective program. Her research projects are regularly chosen by students undertaking their research selected study module (SSM) where they receive intensive one on one teaching. She is also in charge of the overseas medical student elective program.

Radiology is an essential and very important part of medical education and students at CUHK have benefitted from structured radiology teaching for over 15 years. The future direction is to continue developing radiology teaching, incorporating new pedagogies to strengthen the teaching, ensure that radiologists retain a strong input in radiology teaching, and the profile of radiology is raised with the next generation of doctors.  


Professor Ann King has been the head of radiology resident training since 2000 and program director of the new territories east cluster training. Over this period radiology training has undergone considerable changes with the implementation of a structured program and log books by the Hong Kong College of Radiologists. Trainees are supervised to levels above those set by the college and trainees successfully pass the examination for the FRCR (joint examination with the Royal College of Radiologists UK) and exit examination of the FHKCR. Professor King was in charge of the successful application for PWH training re-accreditation by the Hong Kong College of Radiologists in 2002, 2007, 2012 and 2017. She also teaches on training courses.

Local, regional and international teaching

She is a regular speaker and teacher at regional and international meetings including the International Congress of Radiology, European Congress of Radiology, International society for magnetic resonance in medicine, International Cancer Imaging Society, European Society of Head and Neck Radiology, British society of head and neck Radiology, Australia & New Zealand Society of Neuroradiology, Singapore Congress of Radiology, College of Radiology Academy of Medicine of Malaysia and interdisciplinary conferences related to nasopharyngeal carcinoma.

Service Profile

Professor Ann King was recruited in 1995 to help set up the new MRI service and subsequently set up the head & neck MRI service. She currently provides regular weekly clinical service sessions for the public and private patients at the Prince of Wales Hospital. Her main expertise remains in MRI where she provides frontline imaging service sessions covering MRI of the head & neck and neuroimaging, but also provides services in ultrasound of the head & neck, CT of the head & neck and CT in general oncology, plus additional input into clinico-radiological conferences, PET/CT and ad hoc consultations. She works closely with her head and neck colleagues in oncology, radiotherapy and surgery, and provides support for the local and international clinical trials in head and neck cancer. She also provides imaging support to the neurosurgeons and neurologists.

Professor King is an Honorary consultant in the Department of imaging and interventional radiology in the Prince of Wales hospital and Honorary Consultant in the New territories east cluster. She is a member of the departmental senior staff committee and over the years has taken up many departmental management roles including MRI service co-ordinator and infection control co-ordinator during the 2003 Hong Kong outbreak of severe acute respiratory syndrome (SARS).

Professor King has given over 14 years of service to the Hong Kong College of Radiologists where she has been a member of the education committee since 2003. Over this period the committee established the guidelines for radiology training in Hong Kong which cover hospital, trainer and trainee requirements. The latter include levels of direct supervision, workload for all imaging investigations, clinic-radiological conferences, audit, quality assurance, teaching and research. These guidelines were set up well before those in the sister College in the UK. Subsequently through this committee, training course subcommittee and accreditation subcommittee she has helped to develop and monitor the training and teaching courses in Hong Kong, and been a senior member on hospital re-accreditation assessments in 2007, 2012 and 2017. Professor King has also been an examiner for joint the Royal College of Radiologists UK and the Hong Kong College of Radiologists Final Examination for the Fellowship, and the Hong Kong College of Radiologists Exit Examination from 2005-2014.

Research Profile

Professor Ann King is an academic radiologist specialising in head and neck radiology with over 20 years of experience in MRI research of head and neck tumours. She has published 170 journal and 164 conference papers.  In 2017 her h index and total number of citations was 36 and 3921 (web of science), 39 and 4440 (Scopus) and 50 and 6926 (Goggle scholar).

Professor Ann King’s interest in academia began in 1988 at the Hammersmith Hospital/Royal postgraduate medical school followed by the Middlesex/ University College Hospital, London UK, before moving to the Chinese University of Hong Kong in 1995 with the opening of the new MRI service.  

MRI of Nasopharyngeal Carcinoma

Professor King’s main research area is MRI of nasopharyngeal carcinoma, a cancer that is endemic in Hong Kong. She has published over 50 papers in the subject and her MD entitled “Magnetic resonance imaging of the head and neck in nasopharyngeal carcinoma” was awarded with commendation in 2008. She has been using MRI to routinely stage nasopharyngeal carcinoma for more than 20 years, and her earliest published works in this field were amongst the first to report the MRI patterns of primary tumour spread and nodal spread in this disease. Subsequent publications were amongst the first to compare MRI and PET/CT staging, and describe a wide range of treatment induced complications on MRI. Her work in staging continues today with the current emphasis on anatomical and functional MRI markers for distant metastases. Her other major direction of current research is the role of MRI in the early detection of nasopharyngeal carcinoma. Her work was the first to prospectively compare MRI and endoscopy for NPC detection and show that 10% of NPCs are endoscopically occult. Subsequent work has shown that MRI can detect NPC up to three years before endoscopy, and confirmed the high diagnostic accuracy of the proposed MRI criteria for detecting NPC and distinguishing early mucosal NPCs from benign mucosal hyperplasia. MRI is now being used as an adjunct tool for NPC detection in EBV DNA population screening programs, including in Hong Kong (NEJM publication) and by invitation from the U.S. National Cancer Institute in a project in China with Sun Yat-Sen University Cancer Centre and Sihui Cancer Institute, Guangzhou, and VU Medical Center in the Netherlands.

Functional/Molecular MRI of Head & Neck tumours

Professor King’s other main area of MRI research is functional/molecular MRI. She has been researching advanced MRI techniques in head and neck tumours, including early intra-treatment response in squamous cell carcinoma, since 2001. Early work focused on proton spectroscopy and diffusion weighted imaging, followed by DCE MRI. The first papers in DWI and MRS were amongst the pioneering group of publications in in-vivo cancer imaging, an area which today is the major field for cancer imaging. Currently she is working on CEST imaging, and in collaboration with Johns Hopkins USA published the first feasibility study using amide proton transfer in the head and neck. She has worked closely with medical physicists and scientists to overcome the challenges of performing MRI in the head and neck. She has published over 30 papers in this topic, including technical papers and those related to tumour characterisation, prediction of treatment response (pre-treatment and early intra-treatment) and identification of residual cancer post-treatment.

MRI of the Post-treatment Neck

Post chemoradiotherapy assessment is one of the most challenging fields in head and neck imaging and forms a large part of the imaging service in head and neck oncology centers. Professor King has published widely on the post-treatment neck including functional imaging and refinement of anatomical criteria for detection of residual disease.

MRI of Head & Neck lymphoma, Lymph nodes and Thyroid Cancer

Professor King has published papers on the appearances of a range of head and neck lymphoma, lymph nodes and several reports on thyroid cancer.

Professor King and her team have received awards for their work, she has received competitive grants related to NPC and functional imaging as the principal investigator, written book chapters, invited reviews and is a regular invited speaker at international conferences and workshops in MRI of the head and neck.
