MRI in Cancer Diagnosis at the National Cancer Centre Singapore

Magnetic Resonance Imaging (MRI) is a medical diagnostic technique and an essential tool in cancer diagnosis and treatment. At the National Cancer Centre Singapore (NCCS), MRI scans are performed by experienced radiographers using advanced technology to obtain clear, detailed images that help radiologists diagnose conditions and make informed decisions about patient care.

What Is an MRI Scan

An MRI scan is a non-invasive imaging procedure that uses magnetic fields and radio waves to create detailed pictures of the inside of the body. Unlike X-rays or CT scans, MRI does not involve ionising radiation (e.g. X rays), making it a safe option for visualising soft tissues, organs, and blood vessels.

How MRI Supports Cancer Diagnosis and Treatment

At NCCS, MRI is part of a coordinated, multidisciplinary approach to cancer care. Each scan provides crucial insights that guide diagnosis, treatment planning, and ongoing management.

• Precision in diagnosis and staging cancer: MRI delivers high-resolution images that allow radiologists to see how advanced the cancer is, how far it has spread to other organs, and to see its relation to important adjacent structures such as blood vessels or nerves. 
• Treatment planning: The detailed imaging supports surgeons and oncologists in tailoring treatment strategies to individual needs. 
• Monitoring tumour response: Follow-up MRI scans help evaluate how a tumour responds to treatment, enabling timely adjustments. 
• Monitoring for cancer recurrence: Imaging can be used to see if a previously treated cancer has recurred. 
• Collaborative review: Results are discussed at multidisciplinary tumour board meetings to ensure a complete, patient-centred perspective on care.

Patient Preparation and Safety

MRI is a safe and well-tolerated procedure for most patients. However, certain conditions require special attention to ensure safety.

• Inform your care team if you have metal implants, pacemakers, stents, or other devices. 
• You may be asked to remove metallic objects such as jewellery as they cannot be brought into the MRI scanner. 
• You will need to change into a gown to be comfortable for the scan. 
• Some examinations require an injection of contrast material to improve visibility of tissues or blood vessels. ● The scan is painless, though you will need to remain still to obtain clear images.

NCCS’s radiographers and nurses will guide you through the process and ensure you are comfortable throughout the procedure.

What to Expect

1. Referral and Scheduling

Your doctor at NCCS will arrange the MRI as part of your diagnostic or treatment plan.

2. Before the Scan

You will receive instructions about preparation and safety. Any medical conditions or prior imaging will be reviewed.

3. During the Scan

You will lie on a scanning bed that slides into the MRI scanner. The procedure typically lasts between 20 and 60 minutes, depending on the body area being examined.

4. After the Scan

You may return to your usual activities unless advised otherwise. The radiologist will interpret the images and share the results with your care team.
