Abstract

Purpose: We wanted to evaluate the usefulness of 3D isovoxel MR imaging using 3T MRI in the wrist joint, as compared with 3T MR arthrography. Materials and Methods: A total of 33 patients underwent both MR arthrography and 3D isovoxel imaging of the wrist joints using 3T MR, including 11 patients with arthroscopic confirmation. 3D isovoxel MR imaging was performed using an intermediate-weighted fast spin echo coronal scan with a 0.4-mm slice thickness and the axial images were reconstructed with a 1-mm slice thickness. One radiologist evaluated for the presence of scapholunate or lunotriquetral ligament tear and she determined the grade of the triangular fibrocartilage complex tear and chondromalacia with its location. We compared the two examinations using kappa values. Results: The rates of detecting wrist injury were similar for both exams with substantial to almost perfect inter-examination agreement (kappa value = 0.864 for scapholunate ligament tear, 0.835 for lunotriquetral ligament tear, 0.799 for TFCC tear and 0.940 for chondromalacia). For the eleven cases that underwent arthroscopy, their results of 3D isovoxel MRI were also similar to that of MR arthrography. Conclusion: 3D isovoxel MR imaging is useful for the evaluation of the wrist joint.

목적: 3T MR을 이용한 손목관절의 자기공명 관절조영술과 3차원 등방성 자기공명영상을 비교, 3차원 등방성 영상의 유용성을 평가하고자 하였다. 대상과 방법: 자기공명 관절조영술 및 3차원 등방성 자기공명영상을 모두 시행 받은 33명의 환자를 대상으로 하였고 이 중 11명은 검사 후 관절경 수술을 시행 받았다. 3차원 등방성 자기공명영상은 0.4 mm의 두께로 중등강조 급속 스핀에코 기법을 이용하여 관상면 스캔을 시행하였다. 각 검사에서 주상월상인대, 월상삼각인대, 섬유연골복합체 손상 유무 및 연골연화증을 평가하였고 카파 값을 구해 비교하였다. 결과: 두 검사 간 손목관절 손상 발견에 대해서 높은 일치도를 보였으며(kappa 값은 주상월상인대 파열 0.864, 월상삼각인대 파열 0.835, 삼각섬유인대 파열 0.799, 그리고 연골연화증 0.940), 수술을 시행 받은 11명에서도 두 검사 모두에서 비슷한 결과를 보였다. 결론: 3차원 등방성 자기공명영상은 손목관절 손상 진단에 유용하다.
