Ovarian cancer is one of the three most common gynecological cancers in the world,and is regarded as a priority in terms of women’s cancer.In the past few years,many researchers have attempted to develop and apply artificial intelligence(AI)techniques to multiple clinical scenarios of ovarian cancer,especially in the field of medical imaging.AI-assisted imaging studies have involved computer tomography(CT),ultrasonography(US),and magnetic resonance imaging(MRI).In this review,we perform a literature search on the published studies that using AI techniques in the medical care of ovarian cancer,and bring up the advances in terms of four clinical aspects,including medical diagnosis,pathological classification,targeted biopsy guidance,and prognosis prediction.Meanwhile,current status and existing issues of the researches on AI application in ovarian cancer are discussed. 展开更多

原发性小肠肿瘤是一类发病率较低的肿瘤,尤其大部分小肠肿瘤是实性成分为主,病变在多层螺旋CT(multislice spiral CT,MSCT)平扫上通常很难发现、且表现类似,彼此难以鉴别。本文描述小肠实性或实性成分为主的肿瘤的MSCT增强扫描技术和影... 原发性小肠肿瘤是一类发病率较低的肿瘤,尤其大部分小肠肿瘤是实性成分为主,病变在多层螺旋CT(multislice spiral CT,MSCT)平扫上通常很难发现、且表现类似,彼此难以鉴别。本文描述小肠实性或实性成分为主的肿瘤的MSCT增强扫描技术和影像学特征,包括对比剂的类型和使用方法。在MSCT增强扫描检查方法中,CT小肠造影的优点是可以确定肠壁病变的真实范围、可能的透壁范围、肠系膜受累程度、远处转移、有助于发现和识别小肠肿瘤的供血血管、评估相应并发症;已经成为诊断、评估和分期小肠实性或实性成分为主肿瘤的最佳无创性成像技术。CT纹理分析(CT texture analysis,CTTA)作为新的研究热点,为原发性实性成分为主小肠肿瘤正确诊断提供了可能性。 展开更多

Radiology(imaging) and imaging-guided interventions, which provide multi-parametric morphologic and functional information, are playing an increasingly significant role in precision medicine. Radiologists are trained to understand the imaging phenotypes, transcribe those observations(phenotypes) to correlate with underlying diseases and to characterize the images. However, in order to understand and characterize the molecular phenotype(to obtain genomic information) of solid heterogeneous tumours, the advanced sequencing of those tissues using biopsy is required. Thus, radiologists image the tissues from various views and angles in order to have the complete image phenotypes, thereby acquiring a huge amount of data. Deriving meaningful details from all these radiological data becomes challenging and raises the big data issues. Therefore, interest in the application of radiomics has been growing in recent years as it has the potential to provide significant interpretive and predictive information for decision support. Radiomics is a combination of conventional computer-aided diagnosis, deep learning methods, and human skills, and thus can be used for quantitative characterization of tumour phenotypes. This paper discusses the overview of radiomics workflow, the results of various radiomics-based studies conducted using various radiological images such as computed tomography(CT), magnetic resonance imaging(MRI), and positron-emission tomography(PET), the challenges we are facing, and the potential contribution of radiomics towards precision medicine. 展开更多
