The increasing distribution of high-field (3 T) magnetic resonance (MR) systems for clinical use has been accompanied by the need to fully understand the advantages and disadvantages that the increase in signal quality confers. Continuous development of the coils is required to fully express the potential of these systems, especially given the synergy between parallel imaging and the recent multichannel phased-array coils, which are able to improve image quality, spatial resolution and diagnostic accuracy in musculoskeletal imaging. The increase in signal offered by the high field makes possible improved visualisation of bone, cartilage, tendons and ligaments. This advantage, together with increased spatial resolution, is particularly useful when studying joints or some of their components, the evaluation of which has produced suboptimal results in non arthrographic examinations such as the glenoid labrum of the shoulder and the articular cartilage of the knee. Thanks to the greater signal-to-noise ratio and improved spatial resolution, MR imaging at 3 T is able to notably increase diagnostic performance in the musculoskeletal setting, with a consequent improvement in patient treatment and management.
高场（3T）磁共振（MR）系统在临床应用中的分布越来越广泛，随之而来的是需要充分了解信号质量提高所带来的优势和劣势。为了充分发挥这些系统的潜力，需要不断开发线圈，特别是考虑到并行成像和最近的多通道相控阵线圈之间的协同作用，这些线圈能够提高肌肉骨骼成像的图像质量、空间分辨率和诊断准确性。高场提供的信号增加使得骨骼、软骨、肌腱和韧带的可视化成为可能。这一优势，再加上更高的空间分辨率，在研究关节或其某些成分时特别有用，在非关节造影检查中，如肩部的肩盂唇和膝关节的关节软骨，这些成分的评估结果并不理想。由于信噪比和空间分辨率的提高，3T 磁共振成像能够显著提高肌肉骨骼成像的诊断性能，从而改善患者的治疗和管理。
