Objective To compare the accuracy rate of talar osteochondral lesions between the small field of view (FOV) surface coil MR imaging and 2D FSE proton density weighted imaging (2D-FSE-PD)， 3D-SPACE sequences MR imaging with boot-shaped coil. Methods Totally 43 patients (45 ankles) underwent 3D-SPACE sequence after 2D-FSE-PD sequence scanning using the boot-shaped coil， then the PDWI sequence was scanning after the boot-shaped coil was replaced by the small FOV surface coil at 1.5T MRI. The results of the arthroscopic examinations was regarded as the standard for assessing the accuracy rate of the three methods. Results The accuracy rate of 2D-FSE-PD sequence with small FOV surface coil was 86.67% (39/45)， the accuracy rate of 2D-FSE-PD sequence with boot coil was 60.00% (27/45)， the accuracy rate of 3D-SPACE sequence with boot coil was 68.89% (31/45). The accuracy rate of small FOV surface coil was higher than those of boot coil used 3D-SPACE sequence (χ2=4.114，P=0.002) and boot coil used 2D-FSE-PD sequence (χ2=8.182，P<0.001). There was not significant difference between 3D-SPACE sequence using boot coil and 2D-FSE-PD sequence using boot coil (χ2=0.776，P=0.125). Conclusion Compared with the 2D-FSE-PD and 3D-SPACE sequences with boot-shaped coil， the small surface coil scanning with routine sequence can show talar osteochondral lesions better.
