基于MRI的影像组学在软组织肿瘤中的研究进展

Research Development of Radiomics Based on MRI in Soft Tissue Tumors

软组织肿瘤组织学成分种类多样,生物学行为差异巨大。MRI具有多平面成像和较好的软组织分辨率,成为软组织肿瘤首选的影像学检查方法。然而,常规MRI仅局限于解剖学的辨认和病变信号特征的识别,诊断效能存在局限性。影像组学可基于医学图像提取并分析大量非可视化信息,通过对感兴趣区分割、高通量信息提取及模型建立,实现对医学图像所包含信息的更深层次分析和应用。本文针对影像组学在软组织肿瘤中的研究进展进行阐述。

Various characteristics of histological components and great differences ofbiological behavior are performed in soft tissue tumors(STTs).According to the multi-planar imaging protocols and better soft tissue resolution,MRI has become a preferred imaging approach of diagnosis of STTs.However,conventional MRI technologies are exclusively to identify the anatomy and pathological signal features,with the limitation of diagnostic efficiency.Non-visual information could be extracted and analyzed via radiomics based on medical imaging.The medical imaging contained deeper analysis and full use of the information could be further realized by segmenting regions of interest,extracting high-throughput information and building models.This article reviews the latest developments in radiomics based on MRI in STTs.
