影像学检查在肺癌的诊断和分期中起到了至关重要的作用,目前电子计算机体层成像(CT)和正电子发射断层成像技术以及磁共振成像(MRI)已经被广泛的应用于肺癌的分期和疗效评估。其中MRI不仅能提供形态学信息,近年来发展起来的磁共振功能成像能提供更多的功能信息。磁共振扩散加权成像(Diffusion-weighted imaging,DWI)是最常应用于临床的磁共振功能成像序列。最初主要应用在神经系统,随着磁共振成像序列的不断发展以及软硬件的开发应用,其在腹部和盆腔的应用也日趋广泛,然而胸部DWI成像仍待普及和更多认识。本文就肺部DWI成像在良恶性病变鉴别、恶性肿瘤的筛查、分期、以及治疗疗效评估方面进行综述。
Radiography has played a crucial role in the diagnosis and staging of lung cancer. At present, computed tomography (CT) and positron emission tomography (MRI) and magnetic resonance imaging (MRI) have been widely used in the staging of lung cancer Efficacy evaluation. Among them, MRI can not only provide morphological information, but functional magnetic resonance imaging developed in recent years can provide more functional information. Diffusion-weighted imaging (DWI) is the most commonly used magnetic resonance imaging sequence in clinical practice. Initially mainly used in the nervous system, with the continuous development of magnetic resonance imaging sequences and hardware and software development and application of its abdominal and pelvic applications are also increasingly widespread, but the chest DWI imaging remains to be universal and more understanding. In this paper, lung DWI imaging in the identification of benign and malignant lesions, screening of malignant tumors, staging, and evaluation of therapeutic efficacy are reviewed.
