CT Scan


The invention of computed tomography is considered to be the greatest innovation in the field of radiology since the discovery of X-rays. This cross-sectional imaging technique provided diagnostic radiology with better insight into the pathogenesis of the body, thereby increasing the chances of recovery. In1979, G.N. Hounsfield and A.M. Cormack were awarded the Nobel Prize in medicine for the invention of CT. Today, CT is one of the most important methods of radiological diagnosis. 

The scan produces a series of images and can detect many conditions that do not show up on conventional x-rays. Your doctor has ordered this examination to help make an accurate diagnosis of your condition. The results help determine the best course of treatment for you.

During the scan, a thin beam of x-rays is focused on a specific part of your body, such as the head, chest, liver, spleen, pancreas, adrenal glands, kidneys, or spine. The x-ray tube moves rapidly around this site, enabling multiple images to be made from different angles to create cross-sectional picture. The x-ray beam is picked up by an electronic detector which records the information and feeds it into a computer.

The computer then analyzes the information and constructs an image on a monitor screen including a volume display of your organ. During some CT scans, a contrast medium (commonly called "dye") is used to outline blood vessels or highlight organs of the body (eg, liver, kidneys) so that they can be seen more easily.

The department have installed two CT  :

  1. 1.GE LightSpeed Plus 4 Slice CT in Disember 2000
  2. 2.Siemens Somatom Definition AS+ 128-Slice in May 2009


We have performed more than 5000 CT examinations every year.

                2008       =             5316

                2009       =             5717

                2010       =             6161

All CT examinations are stored and can be accessed by doctor from Picture Archiving and Communication System (PACS).



Computed tomography is offered for diagnostic.  In Department of Radiology, HUSM CT examinations are scheduled by appointment.  We also accept urgent for trauma and emergency  cases from this hospital and other hospitals.

We offer standard CT Studies as well as high resolution and 3D CT Angiography for diagnostic studies of all parts of the body. The following are some examples of the CT examinations :

  • CT of the head, neck, chest, abdomen, pelvis, extremities and spine examinations
  • High Resolution CT (HRCT) of Lung and Internal Auditory Meatus
  • Calcium Scoring CT
  • Coronary CT Angiography
  • CT Angiography of selected regions (e.g. CTA Mesenteric & CTA Pulmonary)
  • Virtual Colonoscopy / CT Colonography
  • CT Urography
  • CT guided biopsy
  • CT Planning for radiotherapy
  • CT for Image Guided Surgery (IGS)

Besides that, the department is actively conducting many clinical research projects in the areas of computed tomography (CT).


The department has a dedicated CT Team which is responsible for prescribing CT protocols, provide training regarding techniques, procedures and image processing to the staff besides responsible to maintainmodalities and make sure CT suite in good condition. The team member consists of :

  • En. Nik Fauriza b. Nik Lah
  • Pn. Norfataha bt. Mohd Daud
  • Pn. Aslinda bt. Ibrahim
  • En. Mohd Shazreel Rizal b. Shukri
  • En. Ooi Kiean Lim
