640-Slice C.T. Scan


Computed tomography scan, commonly known as CT scan, functions by gathering a series of X-ray images taken of the body from different angles and employs computer processing to generate cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. This non-invasive exam provides anatomical information quickly and accurately, which assists your physician in making accurate diagnosis and treatment recommendations.



Our Imaging Department is home to an advanced 640 Slice Toshiba Aquilion One CT Scanner. One of the most revolutionary and the world’s first dynamic volume CT scanner. Apart from routine examination, the scanner also performs CT angiography (CTA) to help physicians evaluate the arteries and assess their function.

Our 640-Slice CT Scanner is able to observe anatomy and detect the degree of coronary heart disease in as little as ONE heart beat scan. Another benefit to our 640-Slice CT Scanner is the improved accuracy in analysis as a result of the high definition images produced.



Prior to undergoing a CT examination, it is imperative that you consult with your doctor regarding the do’s and don’ts as different examinations require different preparations. Below are some of the common preparation steps:

  • Refrain from eating at least 4 hours before a CT scan. You are allowed to drink plain water.
  • You will be required to remove metal objects, such as belts, jewellery, dentures and eyeglasses, which may interfere with image results.
  • Only for contrasted CT scans, you may be required to perform a blood test to check the kidney function by observing Creatinine and eGFR result before the scan. Bring along a recent (last 1 months) blood result if any.
  • For child bearing women/girl (age: 9-50 years), you may be required to perform a urine test / blood test (Beta hCG) if your period is delayed or if you might be pregnant.
  • You may be required to drink an oral contrast agent approximately 30-60 minutes before the abdomen or abdomen/pelvis scan.
  • For the scan involving the pelvis region, you are required to have the rectal contrast.
  • You may be requested to have an IV-line insertion in your vein (hand or arm) for contrast agent (dye) administration.



During the procedure:

  • CT scanners bear great resemblance to a large doughnut. During the procedure, you will be instructed to lie on a table that slides in and out of the CT scan gantry. Straps and pillows may be used to help you maintain the correct position as well as maximize comfort.
  • While scanning, the detectors and the X-ray tube inside the gantry will rotate around you to capture images from various angles. During the examination, you will be in the room alone; however, the radiographer will be able to see and hear you throughout the entire procedure. You may be asked to hold your breath for a short period during the scan to improve accuracy and prevent image blurring.
  • A routine scan takes approximately 5-15 minutes to complete, depending on the area that is being scanned and the complexity of the protocols involved.
  • Depending on the type and region of scan requested, many CT scans require an iodinated contrast dye to be administered. You may experience a feeling of warmth during the injection or a metallic taste in your mouth which is completely normal. The purpose of the dye will increase the visibility of organs and other structures as well as the presence of disease.

After the procedure:

  • After the examination, you can return to your normal routine, either return to the doctor’s clinic or proceed with payment and go home.
  • In some cases, after the contrast injection, you may be asked to wait for a short time before leaving to ensure your wellbeing after the examination. Also, the IV line will be removed if no hospital admission is required.
  • You are advised to drink plenty of fluids to help your kidneys remove the contrast material from your body unless your doctor tells you otherwise.



  • CT images are stored as electronic data files (PACS) and are usually reviewed on a computer screen. Your doctor will view the report through PACS once it is interpreted and approved by the radiologist.
  • Your scan results will be reported within one (1) working day. However, urgent scans are reported within 4 hours.
  • Reports and DVD copies of the CT images will be provided upon request only. Please inform the Imaging receptionist (front desk) to prepare it in advance should you wish to collect it after consultation. Preparation of the DVD will take approximately 15 minutes.



All outpatients going for CT examination are required to make an appointment prior to the examination. Your appointment can be made through your referring doctor.

Our operating hours are from 8:30am to 4:30pm on weekdays and 8:30am to 1:00pm on Saturdays.
