mFFE MRI Versus CT for Cortical Bone Evaluation in Knee Osteoarthritis
Beyond Conventional MRI: Multi-Echo Fast Field Echo (mFFE) MRI for Cortical Bone Evaluation in Knee Osteoarthritis Compared With CT
研究概览
详细说明
Knee osteoarthritis involves microstructural alterations in subchondral and cortical bone. Conventional MRI has limitations in visualizing cortical bone due to short T2 relaxation times. Multi-echo fast field echo (mFFE) sequences can produce CT-like images of cortical bone without ionizing radiation.
This observational study will include patients aged 40 years or older with clinically suspected or confirmed knee osteoarthritis. All participants will undergo both mFFE MRI and CT of the knee. The accuracy of mFFE MRI in detecting cortical bone degenerative changes will be compared with CT as the reference standard.
