Big data is extremely large amount of data which is available in the radiology department. Big data is identified by four Vs - Volume, Velocity, Variety, and Veracity. By applying different algorithmic tools and converting raw data to transformed data in such large datasets, there is a possibility of understanding and using radiology data for gaining new knowledge and insights. Big data analytics consists of 6Cs - Connection, Cloud, Cyber, Content, Community, and Customization. The global technological prowess and per-capita capacity to save digital information has roughly doubled every 40 months since the 1980's. By using big data, the planning and implementation of radiological procedures in radiology departments can be given a great boost. Potential applications of big data in the future are scheduling of scans, creating patient-specific personalized scanning protocols, radiologist decision support, emergency reporting, virtual quality assurance for the radiologist, etc. Targeted use of big data applications can be done for images by supporting the analytic process. Screening software tools designed on big data can be used to highlight a region of interest, such as subtle changes in parenchymal density, solitary pulmonary nodule, or focal hepatic lesions, by plotting its multidimensional anatomy. Following this, we can run more complex applications such as three-dimensional multi planar reconstructions (MPR), volumetric rendering (VR), and curved planar reconstruction, which consume higher system resources on targeted data subsets rather than querying the complete cross-sectional imaging dataset. This pre-emptive selection of dataset can substantially reduce the system requirements such as system memory, server load and provide prompt results. However, a word of caution, "big data should not become "dump data" due to inadequate and poor analysis and non-structured improperly stored data. In the near future, big data can ring in the era of personalized and individualized healthcare.
大数据是放射科可用的海量数据。大数据由四个“V”来定义——容量、速度、多样性和准确性。通过应用不同的算法工具并将原始数据转换为如此大型数据集中的转换后数据,就有可能理解和使用放射学数据以获取新知识和见解。大数据分析包括6个“C”——连接、云、网络、内容、社区和定制。自20世纪80年代以来,全球存储数字信息的技术能力和人均容量大约每40个月就会翻一番。通过使用大数据,放射科放射学程序的规划和实施可以得到极大的推动。大数据在未来的潜在应用包括扫描调度、创建针对患者的个性化扫描方案、放射科医生决策支持、紧急报告、放射科医生的虚拟质量保证等。通过支持分析过程,可以针对图像有针对性地使用大数据应用。基于大数据设计的筛查软件工具可用于通过绘制其多维解剖结构来突出感兴趣区域,如实质密度的细微变化、孤立性肺结节或局灶性肝病变。在此之后,我们可以运行更复杂的应用,如三维多平面重建(MPR)、容积再现(VR)和曲面平面重建,这些应用在目标数据子集上消耗更高的系统资源,而不是查询完整的横断面成像数据集。这种对数据集的预先选择可以大幅降低系统要求,如系统内存、服务器负载,并提供快速结果。然而,需要提醒的是,“如果分析不足、质量差且数据存储不结构化、不当,大数据不应变成‘垃圾数据’”。在不久的将来,大数据可以迎来个性化和个体化医疗的时代。
