Abstract

The utility of a specially dedicated quadrature detection (QD) mode limb coil for the MR evaluation of peripheral joints has been evaluated. High resolution images of the knee, elbow, wrist and ankle provided excellent anatomical delineation of the cortical and medullary bone, cartilage, ligaments and menisci over a homogeneous field of view. Pathological conditions including meniscal injury, fracture and osteonecrosis were accurately detected. The QD limb coil can be advantageously used for the MR evaluation of peripheral joints at an intermediate field strength.

摘要

一种专门用于外周关节磁共振（MR）评估的正交检测（QD）模式肢体线圈的效用已得到评估。膝关节、肘关节、腕关节和踝关节的高分辨率图像在均匀视野范围内对皮质骨和髓质骨、软骨、韧带和半月板提供了出色的解剖学描绘。包括半月板损伤、骨折和骨坏死在内的病理状况被准确检测到。QD肢体线圈可有效地用于中场强下外周关节的MR评估。
