The best MRI approach for cartilage uses high‑resolution proton‑density (PD)–weighted images with fat suppression for morphological detail, combined with 3D spoiled gradient‑echo sequences (e.g., DESS/SPGR) for surface and thickness assessment. For early or biochemical changes, quantitative techniques such as T2 mapping and T1ρ are most sensitive to cartilage composition and degeneration.

Yes. MRI can detect knee cartilage damage, showing defects’ location, depth (partial- or full-thickness), and associated findings (bone marrow edema, meniscal or ligament injury). Standard MRI is good for moderate-to-large lesions; dedicated cartilage sequences, 3T scanners, MR arthrography or quantitative techniques (T2 mapping, dGEMRIC) improve sensitivity for early or subtle degeneration. Arthroscopy may be used if imaging is inconclusive.

A knee MRI cost varies by country and facility. In the United States typical billed prices range from about $400 to $3,000 or more; in India common rates are roughly ₹2,000–₹10,000. In countries with public health coverage the scan can be provided free, while private MRI usually costs about £200–£700 in the UK. Final out‑of‑pocket cost depends on contrast use, facility type, and insurance coverage.

Knee cartilage damage can be serious depending on severity and location. Small lesions may heal or be managed conservatively, but larger or untreated defects often cause pain, swelling, reduced mobility and increase risk of osteoarthritis and long-term disability. Early diagnosis and tailored treatment—physiotherapy, weight management, injections or surgery—improves outcomes. Seek medical review for persistent pain, locking, instability or swelling.

Treat knee cartilage damage first with rest, activity modification, ice, NSAIDs for pain, and physiotherapy to strengthen muscles and improve joint mechanics. Weight loss, braces or orthotics reduce load. Injections (steroid, hyaluronic acid, or PRP) may relieve symptoms. For persistent or large defects, surgical options include microfracture, cartilage grafting or knee replacement. See an orthopaedic specialist and get imaging (X‑ray/MRI).

In MRI, a sequence is a programmed set of radiofrequency pulses, gradient changes and timing parameters (TR, TE, flip angle) used to produce a particular image contrast and type. Different sequences (T1, T2, FLAIR, diffusion, STIR, GRE) highlight specific tissue properties, suppress or accentuate signals, and affect spatial resolution, scan time and sensitivity to motion, flow or artifacts.
