Imaging plays an essential role in diagnosing and managing musculoskeletal soft tissue masses. It provides anatomic details and aids in the characterization and prognostication of tumors. Advanced imaging is also essential for assessing treatment response and post-treatment surveillance. Several novel imaging techniques are now available that provide additional functional and metabolic information about these tumors. This additional information may be used to predict the biological behavior of the tumors and effectively assess the treatment response for optimizing their management. This article focuses on multiparametric imaging evaluation of soft tissue masses with a discussion of advancements in the domains of ultrasound, MRI, and CT imaging and how these may be helpful in pre- and post-treatment assessment of soft tissue tumors. Current perspectives on the role of diffusion imaging, perfusion imaging, and MR spectroscopy have been highlighted, and future directions of metabolic imaging are briefly outlined. As these advances hold a promising role in the multidisciplinary management of soft tissue sarcomas, it is important for the radiologist to be familiar with the latest advances and developments in imaging soft tissue tumors.
影像学在诊断和治疗肌肉骨骼软组织肿块中起着至关重要的作用。它提供了解剖学细节，并有助于肿瘤的特征描述和预后判断。高级影像学对于评估治疗反应和治疗后监测也至关重要。现在有几种新的成像技术可提供有关这些肿瘤的额外功能和代谢信息。这些附加信息可用于预测肿瘤的生物学行为，并有效地评估治疗反应，以优化其管理。本文重点讨论了软组织肿块的多参数成像评估，并讨论了超声、MRI 和 CT 成像领域的进展，以及这些进展如何有助于软组织肿瘤的治疗前和治疗后评估。突出强调了扩散成像、灌注成像和磁共振波谱学的当前观点，并简要概述了代谢成像的未来方向。由于这些进展在软组织肉瘤的多学科管理中具有广阔的应用前景，因此放射科医生熟悉软组织肿瘤成像的最新进展和发展非常重要。
