Soft tissue sarcomas (STS) are rare tumours presenting as soft tissue lumps. Ultrasound is often the primary modality for the initial assessment, with MRI the mainstay for lesion characterisation. PET/CT along with other emerging MRI sequences are used in certain situations as an adjunct and problem solving tool in STS staging and assessment of disease recurrence. Recent advances include the promise of whole body MRI, hybrid PET/MRI, diffusion weighted imaging, dynamic contrast enhanced MRI and advances in artificial intelligence. This article discusses current concepts in extremity STS imaging and highlights recent advances.
软组织肉瘤（STS）是一种罕见的肿瘤，表现为软组织肿块。超声通常是初始评估的主要方式，而MRI是病变特征描述的主要手段。PET/CT以及其他新兴的MRI序列在某些情况下用作辅助工具和解决问题的工具，用于STS分期和疾病复发评估。最近的进展包括全身MRI、PET/MRI混合成像、扩散加权成像、动态对比增强MRI的前景以及人工智能的进展。本文讨论了肢体STS成像的当前概念，并强调了最近的进展。
