Computed Tomography (CT)

Computed Tomography (CT) scan utilises computerised x-ray imaging to generate cross-sectional slices of the body, resulting in more intricate tomographic images of various body parts. These images can reveal abnormalities in organs, bones, muscles, and blood vessels with greater detail.
 

Before:

  • CT scan without contrast: you may consume food, beverages, and your prescribed medications before the examination.
  • CT scan with contrast: refrain from eating anything for four hours before the appointment. It is advisable to drink clear liquids, and you can continue taking your prescribed medications (except for anti-diabetic medication) before the scan. If you are taking an anti-diabetic medication called Metformin, kindly stop 48 hours prior to the scan and to resume only 48 hours the scan is completed.
  • Remove any jewellery or metal objects.
  • For a CT scan of the abdomen/pelvis, you may need to drink oral contrast media one hour before the scan, and are advised not to empty your bladder at least one hour before the scan.
  • In selected patients, a serum creatinine blood test might be required to be done before the CT scan examination in order to check your kidney function.

Notify us if you:

 
  • Cancel if you have experience a reaction to contrast media
  • Are pregnant or suspect you might be
  • Are breastfeeding
  • Have any other underlying medical conditions including diabetes mellitus and asthma
  • Experience kidney issues such as kidney disease, previous kidney surgery, or dialysis
  • Take any medications, including vitamins, herbal supplements, or other dietary supplements
  • Use diabetic medication
  • Have allergies to medications
 
 

During:

  • For scans involving contrast media, you will need to sign a consent form detailing the risks and potential side effects associated with intravenously injected contrast media.
  • You will lie on a CT table that slides into the scanner, while the staff operates the scanner from a control room. It's important to remain still during the scan to ensure clear images. Inform the staff immediately if you experience any discomfort or unusual sensations.
  • Temporary side effects of IV contrast may include feeling warm, a metallic taste in the mouth, or an urge to urinate, which usually dissipates quickly.
  • The scan may require 15 minutes to 30 minutes. This timeframe doesn not encompass the preparatory phase, which might extend to as long as 90 minutes for a pelvic scan.
 
 

After:

  • If contrast was used, you might be advised to wait for up to an hour to monitor for any adverse reactions. Generally, the intravenous contrast is eliminated by the kidneys within one or two hours.
  • You can resume normal activities, including eating, drinking, working, and driving, after the scan.

Pre-Screening:
 

Fasting may be required 4 to 6 hours before, specifically for blood tests, abdomen, and liver ultrasound.

You may drink water during this fasting period. It is advisable to drink clear liquids, and you can continue taking your prescribed medications (except for anti-diabetic medication) before the scan.

If you are feeling unwell on the day of your screening, we will assist you to reschedule your appointment at your convenience. This is because overall fitness and medication such as antibiotics may affect your screening results.

Day Of Appointment:
 

Please bring along the following:

  • Identification documents for registration
  • Past medical reports and radiology films and/or reports

When registering, you can opt to include add-ons as supplementary components to your health screening programme.

Once you are registered, you will be scheduled for a blood test, diagnostic imaging test, clinical examination, and a consultation with a doctor.

The entire screening process may take 2 to 4 hours, depending on the package selected.

Light refreshment will be provided after the screening.

Urine Collection
 
  • Clean your hands thoroughly and use tissue paper to wipe your genital area.
  • Hold the specimen bottle without touching the inside.
  • Start urinating into the toilet bowl. After a few seconds, while continuing urination, position the specimen bottle in the urine stream to collect urine directly until it is half-full.
  • Securely fasten the cap onto the specimen bottle and place it in the provided Ziploc bag.
Post-Screening:
 
  • Results will usually be ready in 24 hours or more, contingent on which tests you have undergone.
  • We will schedule an appointment for a one-on-one review with our physician, who will go over your results and offer personalised recommendations tailored to your requirements.
