Selecting the appropriate imaging modality is critical. At Halifax Infirmary—part of the QEII Health Sciences Centre—clinicians rely on both MRI and CT scans to deliver precise diagnoses. But the choice isn’t arbitrary. Each modality excels in specific medical scenarios halifax infirmary diagnostic imaging, guided by factors like urgency, tissue type, patient safety, and technology availability.
Understanding the Technologies
CT (Computed Tomography)
Utilizes X-rays and computer synthesis to create cross-sectional images. It’s fast and excellent for visualizing bone, chest, abdomen, and detecting bleeding or clots.
MRI (Magnetic Resonance Imaging)
Employs magnetic fields and radio waves for detailed soft-tissue contrast—ideal for brain, spinal cord, joints, and ligament assessments
Why Halifax Infirmary Chooses CT
In an emergency, speed
CT scans provide incredibly quick results (minutes) when trauma or stroke is suspected, which is crucial for prompt treatment.
Lung and Bone Visualisation
CT is excellent at identifying complicated fractures of the skull, spine, or limbs as well as lung diseases such embolisms or pneumonia.
Cost and Accessibility
CT is more reasonably priced and accessible. Additionally, it presents fewer difficulties for those who are claustrophobic.
Why Halifax Infirmary Chooses MRI
When evaluating neurological, muscle, and ligament conditions (such as brain tumours, disc herniation, and rotator cuff injuries), superior soft-tissue imaging (MRI) offers remarkable detail.
Absence of Radiation Exposure
MRI is safer for repeated usage without ionising radiation, even in pregnant or paediatric patients when needed.
Accuracy in Particular Diagnoses
The clarity of MRI is unparalleled for in-depth brain examinations or suspected spinal cord problems.
Comparing MRI & CT: Key Differences
| Feature | CT Scan | MRI Scan |
| Radiation | Yes (X-ray based) | No |
| Best For | Bones, chest, trauma, quick scans | Soft tissues, brain, joints, ligaments |
| Speed | Minutes | 20–60+ minutes |
| Cost | Lower | Higher |
| Comfort | Less claustrophobic | More enclosed and noisy |
| Safety | Radiation exposure | MRI-safe implant restrictions |
Halifax Infirmary’s Referral Approach
Acute presentation or trauma → CT scan right away (e.g., suspected internal bleeding, head injury).
Neurological issues → MRI for a more thorough evaluation after the initial CT scan (rapid screening).
MRI is the main test for suspected spinal or joint problems unless a quick CT scan is necessary to rule out osseous damage.
Oncology protocols: MRI for conclusive tumour assessment (e.g., prostate, CNS); CT for general staging
Safety & Cost Considerations
CT: Effective but involves radiation—use limited in young, pregnant, or high-risk patients .
MRI: No radiation; however, longer and more expensive. Metal implants and claustrophobia can restrict use
Cost Comparison: CT typically ranges around $500–1,500, while MRI can cost $1,000–3,000 or more
Making the Right Choice: Patient Takeaways
Clinical indication: Adhere to the CT or MRI advice of your healthcare expert.
Choose CT if you need a quick, life-saving evaluation.
Safety profile: When avoiding radiation is important, choose MRI.
Limitations in practice: CT can be preferable if claustrophobic or implanted.
Impact on costs: Examine facility or insurance rates where available.
