A radiomics model from joint FDG-PET and MRI texture features for the prediction of lung metastases in soft-tissue sarcomas of the extremities

In this study, a cohort of 51 patients with histologically proven soft-tissue sarcomas (STSs) of the extremities was retrospectively evaluated. During the follow-up period, 19 patients developed lung metastases. Patients with metastatic and/or recurrent STSs at presentation were excluded from the study. All patients had pre-treatment FDG-PET/CT and MRI scans.

本研究对51例经组织学确诊的肢体软组织肉瘤（soft-tissue sarcomas, STSs）患者队列进行了回顾性评估。随访期间，共有19例患者发生肺转移。初诊时即存在转移性和/或复发性软组织肉瘤的患者被排除本研究。所有患者均接受了治疗前FDG-PET/CT及磁共振成像（MRI）检查。

背景与挑战

背景概述

该数据集基于51名四肢软组织肉瘤患者的回顾性研究，旨在通过联合FDG-PET和MRI纹理特征构建放射组学模型，以预测肺转移的发生。研究排除了初诊时已有转移或复发的患者，所有患者在治疗前均接受了FDG-PET/CT和MRI扫描，其中19名患者在随访期间出现肺转移，为模型开发提供了关键临床数据。
