Kwong Wah Hospital Hospital Authority
Department of Diagnostic Radiology

The KWH introduced X-ray services in 1952. The first X-ray machine was set up at a small house (now demolished) next to the main building (currently Tung Wah Museum in the KWH). Until 1957, given the growing demand for diagnostic imaging services, the KWH Diagnostic Radiology was formally established in 1963 following the completion of the 4th phase redevelopment. Initially, one head x-ray machine was procured in addition to the one existing general X-ray machine, bringing tremendous help to the diagnostic work.


This is our first radioscope, the latest model at the time. Directors of TWGHs were shown visiting the Department (right).

In July 1997, the Department ushered in a new era after a major renovation of the hospital. Besides the fresh setting, we added a lot of advanced medical equipment and large-scale imaging equipment connected by optical fibre, which is capable of transmitting vast amounts of digital images for clinical diagnosis and friendly for storage, thus enhancing our service quality.

At present, the KWH Diagnostic Radiology provides the public with comprehensive diagnostic imaging and treatment services including: radiological scoring, X-ray test, mammography, vacuum assisted breast biopsy, CT scanning, ultrasound scanning, MRI scanning, nuclear medicine scanning, digitalised xx imaging and interventional radiology. What’s more, diagnostic radiological services are available at TWGHs Computed Tomography Imaging Centre and TWGHs Integrated Diagnostic and Medical Centre with an annual attendance of more than 200,000, making it one of the busiest hospitals under the HA.

The Way Forward
We have been striving toward a fully digitalised imaging system, which is expected to be completed this October. The system can provide a more efficient way of saving and transmitting images to the benefit of doctors and the public, and also reduce the environmental impact caused by traditional X-ray plates. After the finalisation of the planned redevelopment of the KWH, the department will also be expanded with the introduction of more diversified, advanced diagnostic equipment which can deliver services of higher quality and efficiency.


Department of Diagnostic and Interventional Radiology

Major Development Milestones in Recent Years:
1963 The Department was formally established
1967 X-ray room at A&E Department was completed; additional staff was hired by the Department for 24-hour A&E support
1969 Cerebral angiography service was provided with the introduction of Serial Changer
1982 The first CT scanner was installed at the KWH, which only provided scanning of the head and took an imaging time of 105s for each cross-sectional image (imaging time can be shorter than 1s now)
1989 The first digital subtraction angiography unit was formally installed, the most advanced of its type in Hong Kong at the time
1990 To raise public awareness of women’s health, the TWGHs set up a Well Women Clinic at the KWH to provide breast and cervical testing for women
1991 The first full-body CT scanner was set up with donation from Hong Kong Jockey Club
1997 With the completion of a large-scale renovation of the KWH, the Department enjoyed a new setting and introduction of a lot of new medical equipment, including a biplane digital subtraction angiography machine, the most advanced model at the time
Cardiac Catheterisation Room was set up on 1/F, East Wing
1998 TWGHs Lee Siu Chung Memorial MRI Centre was established with donation from the TWGHs, equipped with 1.5T MRI unit, the most advanced model at the time; Cardiac Catheterisation Room came into service in April
1999 The Nuclear Medicine Centre was founded with the procurement of nuclear medicine gamma scanner donated by the TWGHs, now capable of providing various nuclear medicine tests for patients at the KWH, Our Lady of Maryknoll Hospital and TWGHs Wong Tai Sin Hospital, including cardiac/renal function tests, full-body bone scan, thyroid/lung/live scan, etc.
2001 A new vacuum assisted breast biopsy unit was added, capable of extracting small breast lumps and calcifications guided by ultrasound and X-ray
2003 SARS caused the worst pandemic in Hong Kong in recent years with 299 deaths including 6 medical personnel; the Department expanded the manpower and equipment to meet the sudden surge in demand for portable X-ray imaging
2004 The TWGHs set up a Well Men Clinic at the KWH, the first centre specially set up for men in Hong Kong to encourage regular health check-ups for men; the Clinic was later renamed TWGHs Integrated Diagnostic & Medical Centre in 2009 to align with service needs
2008 C-arm X-ray unit was introduced to replace the old X-ray machine
2009 The TWGHs introduced 320-slice dynamic volume CT scanner, the most advanced CT scanner in the world at the time. Cardiac Catheterisation Room on 1/F, East Wing was also enhanced with newer, better biplane cardiac catheterisation testing equipment
Sept 2009 Full digitisation for Mammography service
2010 A digitalised X-ray system was set up at Tsui Tsin Tong Out-patient Building, allowing instant transmission of X-ray images to other medical information systems, which not only reduces waiting time but also saves patients the need to commute between Out-patient Building and Main Building
Nov 2011 Filmless KWH except NM modality
Jan 2014 New SPECT(Single Photon Emission Computerized Tomography) CT machine, Full Filmless in the KWH
Dec 2014 New department name – Department of Diagnostic and Interventional Radiology to truly reflect the service provided by our department.
