A CT scan visualizes bone and joint detail well — fractures, bone alignment, osteoarthritis, loose fragments and complex anatomy. It is less accurate than MRI for soft-tissue injuries such as ligaments, menisci and cartilage. When MRI is contraindicated or for surgical planning, CT (or CT arthrogram) can help, but MRI remains the best test for most soft-tissue knee problems.

Costs vary widely: in India about ₹2,000–₹10,000; in the UK an NHS CT is free but private scans run roughly £150–£500; in the US typical billed amounts range from about $300 to $3,000 depending on facility and contrast; in Canada/Australia private scans commonly cost roughly CAD/AUD 200–1,000. Final price depends on location, facility, contrast use and insurance coverage.

MRI is the most informative scan for knee pain when soft-tissue injury (meniscus, ligaments, cartilage) or unexplained symptoms are suspected. Plain X‑ray is usually the first-line test to assess bones and arthritis or to exclude fracture. Ultrasound helps evaluate superficial tendons, bursae and joint effusions; CT is reserved for complex fractures or detailed bony anatomy before surgery.

Yes. CT scans provide excellent detail of bone structures and can detect joint problems such as fractures, alignment abnormalities, osteoarthritis (joint-space narrowing, osteophytes), bone cysts, calcifications, and loose bodies. CT is less sensitive for soft-tissue issues like ligaments, tendons, and cartilage—MRI is preferable for those. CT arthrography can improve cartilage assessment when needed.

Yes. CT scans produce detailed cross-sectional and 3D images of bone, making them excellent for detecting fractures (including complex or subtle ones), bone loss, tumors, infections, and degenerative changes. They’re more sensitive than plain X-rays for complex anatomy and pre-surgical planning. CT is less effective than MRI for soft-tissue detail and involves ionizing radiation, so benefits are weighed against risks.

Knee scan costs vary by type and country. X‑ray: about $20–$200 (or ₹150–₹600, £40–£100). Ultrasound: roughly $50–$400. MRI (most expensive): about $400–$3,500 (private UK £150–£700; India ₹2,000–₹8,000). CT: about $300–$2,500. Public systems (e.g., NHS) cover scans when referred; private fees and insurance significantly affect final cost. Always check local providers or insurers for exact pricing and discounts.
