Magnetic resonance T2* mapping sequence for imaging of talar cartilage injury under traction with the small field of view coil

Quantitative T2* mapping sequence for the imaging of talar cartilage injury under axial traction with the small FOV coil increased the joint space width, allowed for better visualization of the surface contour and layers of talar cartilage, reduced noise and motion artifacts, and improved the display discrimination ability of T2* mapping sequence for different injuries to the talar cartilage.
