Bone in finest detail
Thin-slice cross-sections show fractures, bone spurs, facet joints and the exact shape of nerve exits better than any other study.
Diagnostics · Standard
CT with and without Contrast
Computed tomography, with or without contrast dye, giving detailed cross-sectional images of bone and surrounding structures.
What it is
When bone detail decides
CT rotates an X-ray source around you to build thin slices that a computer stacks into 3D views. Where MRI owns soft tissue, CT owns bone — fractures, spurs, deformity measurements and post-surgical healing are its territory. Contrast dye extends its reach into vessels and inflamed tissue.
Fusion and hardware
After surgery, CT confirms whether bone is bridging into solid fusion and whether implants sit exactly as planned.
Contrast adds soft tissue
Iodine-based dye highlights blood vessels, inflammation and tumours — structures plain CT renders only faintly.
With versus without
Comparing non-contrast and contrast series separates permanent anatomy from enhancing pathology, sharpening the diagnosis.
Common questions
Things patients ask us
Why both with and without contrast?
The plain series maps bone; the contrast series reveals what lights up with blood flow. Together they distinguish, for example, scar from recurrent disc or infection from degeneration.
What must I disclose beforehand?
Contrast allergy, kidney disease, diabetes medication and thyroid conditions all matter. Bring a full medication list so the team can plan safely.
Is the radiation dose high?
CT uses more radiation than a plain X-ray, so it is ordered only when the bone detail genuinely changes the plan — and the protocol is kept as low as reasonably achievable.
How should I prepare?
Follow the instructions you are given — contrast studies sometimes require fasting and a driver is unnecessary, but confirm both beforehand.
