Guide To CT Scans In Singapore 2025

CT scans, or Computed Tomography scans, are diagnostic imaging tools that provide highly detailed cross-sectional images of the body’s internal structures. CT scans are one of the most widely used medical imaging techniques for diagnosing a variety of health conditions. Whether detecting internal injuries, identifying tumours, or assessing organ health, CT scans provide detailed cross-sectional images of the body, enabling doctors to make accurate diagnoses and treatment plans.

CT scanning services in Singapore provide patients and their doctors with the information they need to make accurate diagnoses, make informed decisions, and devise treatment plans accordingly. If you are considering a CT scan in Singapore in 2025, you may have questions about the procedure, preparation, and where to get one. This guide will cover everything you need to know about CT scans—from how they work to the latest advancements—helping you make an informed decision for your health.

What is a CT Scan?

A CT scan uses a combination of X-rays and computer technology to capture detailed images of internal organs, bones, soft tissues, and blood vessels. It creates multiple cross-sectional images, or “slices,” of the internal organs, providing doctors with highly detailed pictures of a patient’s anatomy. Although a CT scan uses X-rays, the X-rays are aimed at the patient and rotated around the body at different angles. Through this technique, a CT scan is able to reveal much more detail than traditional X-rays, helping to identify medical issues that may not be visible with other imaging methods.

When is a CT Scan Needed?

Following are some of the common applications of CT scans.

• Tumor and cancer detection and monitoring their growth.
• Detecting bone fractures and injuries
• Internal organ evaluation for signs of inflammation, infection, or disease.
• Blood clots and stroke detection for timely stroke intervention.
• Guiding biopsy procedures to ensure accurate sampling.

How to Prepare for a CT Scan?

A CT scan is a non-invasive imaging technique that requires a bit of preparation.

Pre-Scan Guidelines for Patients:

• Dress comfortably and avoid wearing jewellery or metal items, as these may interfere with the scan.
• If you are asthmatic, you will be advised to bring your inhaler with you.

Contrast Dye Information:

• In some cases, a contrast agent is administered to highlight specific areas within the body, enhancing the clarity of the images.
• A plastic cannula is inserted into one of the veins in the arm, and the dye is injected.
• Patients who receive a contrast dye CT scan may experience a mild, warm sensation and a metallic taste in the mouth when the contrast is administered. It is essential to inform about any known allergies to contrast dyes with the radiographer or nurse beforehand.

What to Expect During a CT Scan

When you go for a CT scan, you can expect the following:

• The CT scan will generate images of your body’s organs from multiple angles. To ensure images are captured accurately, it is essential for you to remain still throughout the scan.
• You may be required to hold your breath for a few seconds during the scan. Our radiographer will provide you with the breathing instructions, which are important for you to follow.
• The scan usually lasts for 10-15 minutes.

CT Scan Safety and Risks

• Radiation Exposure: CT scans use low levels of radiation, which are carefully managed to minimise exposure while still capturing clear images.
• Precautions for Certain Patients: Special precautions are taken for patients with metal implants or for those who may be sensitive to contrast agents.
• Allergies to Contrast Dye: If you have a history of allergies, especially to iodine-based contrast dyes, inform the nurse or radiographer so appropriate measures can be taken.

Note: RadLink adheres to stringent safety protocols for all patients

After the CT Scan: Getting Your Results

Post-Scan Process:

• Patients who received contrast dye may be advised to drink plenty of water to flush the dye from their system.
• If you are diabetic and take medication for it, you may be advised to withhold the medication for 48 hours after receiving the contrast dye.
• After the scan, patients are generally free to go about their day unless otherwise advised.
• Let your doctor know if you experience any itching and red spots on the body, swollen mouth or eyes, or difficulty breathing after the scan.

Report and Results Timeline:

A radiologist reviews the images and prepares a detailed report that is shared with your referring doctor.

Consultation and Next Steps:

• Following your scan, you may have to arrange a follow-up with your doctor to discuss the findings and future treatment direction.

Frequently Asked Questions (FAQs) About CT Scans

How long does a CT scan take?

Most CT scans are typically completed within 15 minutes, though preparation time may vary based on the need for contrast dye and region.

Is a CT scan safe?

Yes, CT scans are safe, with low radiation exposure managed according to strict safety protocols.

What should I wear for a CT scan?

Wear comfortable clothing and avoid any metal items, including jewellery, that could interfere with the scan.

Will I feel anything during the CT scan?

The CT scan procedure itself is painless. However, if you had a contrast dye, you might feel a mild warm sensation in your body when it is administered.

What should I do if I’m allergic to the contrast dye?

If you are allergic to contrast dye, inform your doctor beforehand so that alternative imaging options or pre-scan precautions may be considered.

When will I get my CT scan results?

Results are generally available within a few days and sent to your referring doctor for review.

What is the difference between CT and other imaging modalities?

X-rays provide a flat, two-dimensional image, whereas CT scans create 3D images by combining multiple X-rays taken from different angles. This feature gives CT scans an edge for diagnosing complex conditions or assessing detailed anatomical structures. CT scans and MRIs are comparable, but CT scans are faster than MRI scans, which makes them ideal for emergency cases or situations requiring quick diagnosis.

What are the benefits of CT imaging?

CT scans provide clear, detailed images, making it easier to identify abnormalities quickly. Their fast-imaging capabilities make them ideal for emergency situations. They offer more in-depth information than standard X-rays, contributing to better diagnostic accuracy.

Is MRI or a CT scan better?

MRI is an imaging technique that does not involve exposure radiation. It offers excellent soft tissue resolution and allows the physician to evaluate soft tissue structures and injuries that cannot be picked up or are not well assessed on X-rays and CT, for example, ligament, muscle, tendon, cartilage, and meniscus injuries, arthritis, and bony stress injury.

A CT Scan uses radiation to reconstruct 3D scan images of bone and soft tissue with very fine bone details. It is used to characterise bone lesions, better visualisation of fractures for surgical planning and in some cases, to assess for bone healing when X-rays are inadequate.

Your physician will determine the best approach tailored to your diagnosis.
