In image-guided health care, radiologists contribute to the entire health care process, well before and after the actual examination, and out to the point at which they guide clinical decisions and affect patient outcome. Because imaging is so pervasive, radiologists who adopt Imaging 3. By doing this, radiologists become more valuable in the new health care setting. The authors describe how informatics is critical to embracing Imaging 3.
Key Words: Imaging 3. Radiologists already are relatively comfortable with IT and can strengthen their position and value to their health system partners by applying, and sharing, their informatics knowledge. Being IT savvy requires both sophisticated informatics tools and the ability to use them. Corresponding author and reprints: J. How to apply these tools in clinical practice is the topic of a separate report.
This model is used to segment the Informatics Scorecard. Diffusion of innovation. Adapted from Rogers . Tools that fail to meet these criteria may be implemented by innovators and early adopters but fail to diffuse to the community at large.
RIS provide work lists of procedures to be performed, track patient scheduling and images, and interface directly with imaging devices. Most store, track, and distribute radiology reports and either interface with or are directly incorporated into electronic health records EHRs. PACS allow distribution of imaging examinations and annotated key images throughout an enterprise and to other authorized providers. They provide the graphical user interface to view and manipulate imaging examinations.
Reports should be compatible with and electronically deliverable to EHRs and billing and coding software.
Most radiologists use at least fundamental advanced image processing and visualization software for multiplanar reconstructions and 3-D reconstructions. Even this level of advanced visualization software provides basic measurements and labeling. Any advanced visualization should include the ability to save key images into PACS, along with annotations and image markups.
Basic teleradiology services are widely used to receive imaging examinations for remote reading and to send imaging examinations to an outside source for interpretation. Minimum requirements for teleradiology tools should include the ability to deliver and receive relevant prior images and all relevant clinical data with appropriate Internet security measures, as described in the ACR white paper on teleradiology .
Occasionally they use relational databases such as SQL. They may write SQL reports or rely on others to write reports that may take weeks or months to obtain. They contain demographic information on patients and contact information on clinicians.
In the future, EHRs will form the cornerstone of health information exchanges. Finally, they allow electronic examination order entry. OECDS helps providers order the most appropriate, cost-effective imaging examinations.
MU mandates patient access to medical information, including radiology reports. These are commonly provided through a patient portal in an EHR. These enterprise VNAs may archive not only radiology images but also every enterprise image, from cardiology to photographs, point-of-care ultrasound, and video from every specialty. These other images have very different use cases.
IT tools allow real-time point-of-care consultation from other radiologists and bidirectional messaging with technologists. Cloud services are starting to be used for image sharing, teleradiology, and advanced image processing and advanced visualization. Cloud services can be used for point-to-point image transfer, which essentially is a replacement for CD-ROM transfer of an imaging examination. These programs improve coding, help monitor rejection rates and patterns, and improve collection rates and schedules.
Many practices also use IT tools to batch-monitor basic elements of their practices, such as which providers refer what types of examinations to the practices, report turnaround time, radiologist productivity, and location of service. These groups are starting to use more sophisticated dimensional databases, such as online analytical processing cubes, which have more powerful analytic capabilities, particularly in terms of how fast new questions can be asked about the data, and may be more secure.
Most have chosen to opt out through Although this approach has advantages for radiologists who work across multiple disparate systems, providers have only a lifetime 5-year period during which they may opt out, and most radiologists are using up this grace period. Even radiologists who have opted out are affected by MU through enterprise EHR implementation and meeting MU requirements for other specialties.
Data may be structured or unstructured. Structured data are discrete, usually relatively simple, and easy to organize. Patient ID numbers are an example, or even turnaround time, which is easily calculated by comparing discrete time stamps.
Unstructured text data contains patterns and information, however, and mature tools used in other industries can be adapted to radiology.
These tools include natural language processing, text analytics, and tagging. Although many radiology practices and enterprises archive data, most analyze no more than small portions of their structured data.
Rarely do they perform analytics on the unstructured data, which is often the most interesting. This is changing, however. IT products and services to provide BI and analytics to radiologists are now commercially available, and innovators and early adopters are starting to install and use these products. It accepts and aggregates data from radiology groups to establish benchmarks for quality improvement, currently about operations, time stamps, and incident reporting.
Sophisticated document management tools, common in other industries, give early adopters the ability to protocol electronically. They allow document import from Microsoft Word or Excel, or they can create documents from stored templates. The most current versions of documents such as procedures and protocols are distributed for approval or viewing using automated routing rules with different levels of user permission to view or alter documents.
Some have multiple-language support and can be used to generate and mail patient reminders. Other practices use it to exchange images and data for accreditation and registries.
They look for novel patterns in health care and imaging data to discover new ways to drive productivity, quality and value. Some of these radiology practices have their own extensive IT departments capable of in-house software development. They make extensive use of application programming interfaces, which allow disparate software components to interact with one another. Innovators are designing in-house software programs such as real-time actionable clinical decision support for clinicians and radiologists.
Some sites are working to provide links in their reports to clinical education and suggested actions or links to clinical specialists within their enterprise. In the near future, this approach will be used for predictive analytics for radiology.
Sophisticated advanced visualization products include multimodality image fusion, quantitative imaging, automated comparison of current and prior examinations for changes, stereoscopic 3-D surgical planning, automated deformable registration of disparate images, 3-D motion analysis, and novel segmentation algorithms. Advanced visualization may be performed by technologists, radiologists or by clinicians at the point of care.
Started with 5 academic centers, this tool is now open to all radiology practices. REST-based tools will allow improved integration among disparate applications, much as Amazon, eBay, and Google allow personalization and seamless interaction among many programs.
It includes assessment of the imaging enterprise structure and outcomes. Data are maintained in a data warehouse. This warehouse has numerous subfunctions. It performs data cleaning, normalization, consolidation, and aggregation. It includes data dictionaries and metadata-handling software and programs for data loading, transformation, and extraction. Data warehouses aggregate data from multiple sources and, if done correctly, improve data quality.
They can restructure data in ways that make sense to users. They allow complex data queries, and advanced systems can perform simulations on the basis of future operational changes.
Thus, implementing these processes now often requires a site to have software development capability and the respect and trust of enterprise IT. It is intended to allow radiologists and radiology departments to understand where they now stand in relation to their peers in terms of IT tools and to provide a roadmap and goals as they work to become radiology IT savvy. Technology adoption follows a bell-shaped curve. Technology diffusion occurs when the innovation is thought to be worthwhile, details about it are communicated among community members over time, and the culture is receptive to change.

In addition to working in real-time on McKesson PACS software, now students will gain hands-on experience working with the latest medical imaging distribution software from Nautilus MatrixRay. In addition, they will gain insights to the cutting edge telehealth platform integrated into the system. PACS management is a growing challenge for Radiology department personnel and vendors. The emergence of the Imaging informatics profession and the PACS Administrator role is an answer to the complexity of the digital imaging environment. PACS management and healthcare informatics require specific knowledge and skills unique to this technology.
Imaging informatics is part of the larger field of clinical informatics which is in turn part of biomedical informatics. Radiology informatics has some overlap with specific parts of the fields of medical physics, computer science, data science, and cognitive science.

Imaging Informatics Professionals IIPs have come to play an indispensable role in modern medicine, and the scope of this profession has grown far beyond the boundaries of the PACS. A successful IIP must not only understand the PACS itself, but also have knowledge of clinical workflow, a base in several medical specialties, and a solid IT capability regarding software interactions and networking. With the introduction of a certification test for the IIP position, a single source was needed to explain the fundamentals of imaging informatics and to demonstrate how those fundamentals are applied in everyday practice.

PACS and Imaging Informatics: Basic Principles and Applications
Быть может, уже поздно. Я сожалею о Дэвиде Беккере. Она изучала записку. Хейл ее даже не подписал, просто напечатал свое имя внизу: Грег Хейл. Он все рассказал, нажал клавишу PRINT и застрелился.
Сьюзан была согласна с этим, но в то же время прекрасно понимала: Фонд электронных границ никогда не узнает, насколько важен и нужен ТРАНСТЕКСТ. Эта машина помогла предотвратить десятки преступлений, но связанная с ней информация строго засекречена и никогда не будет раскрыта. Причина такой секретности проста: правительство не может допустить массовой истерии. Никто не знает, как поведет себя общество, узнав, что группы фундаменталистов дважды за прошлый год угрожали ядерным объектам, расположенным на территории США. Ядерное нападение было, однако, не единственной угрозой. Только в прошлом месяце благодаря ТРАНСТЕКСТУ удалось предотвратить одну из самых изощренных террористических акций, с которыми приходилось сталкиваться агентству.
Профессионализм Хейла достиг высокого уровня, и у него появились знакомые среди интернет-пользователей по всему миру. Он был представителем новой породы киберпсихов и общался с такими же ненормальными в других странах, посещая непристойные сайты и просиживая в европейских чатах. Его дважды увольняли за использование счета фирмы для рассылки порнографических снимков своим дружкам. - Что ты здесь делаешь? - спросил Хейл, остановившись в дверях и с недоумением глядя на Сьюзан. Скорее всего он надеялся, что никого не застанет в Третьем узле. Сьюзан постаралась сохранить спокойствие.
Сидя в одиночестве и собираясь с мыслями, Беккер посмотрел на кольцо на своем пальце. Зрение его несколько прояснилось, и ему удалось разобрать буквы. Как он и подозревал, надпись была сделана не по-английски. Беккер долго вглядывался в текст и хмурил брови. И ради этого стоило убивать. Когда Беккер наконец вышел из Гиральды в Апельсиновый сад, утреннее солнце уже нещадно пекло. Боль в боку немного утихла, да и глаза как будто обрели прежнюю зоркость.
Что ты здесь делаешь? - спросил Хейл, остановившись в дверях и с недоумением глядя на Сьюзан.
Халохот повернулся к алтарю. В тридцати метрах впереди продолжалось святое причастие. Падре Херрера, главный носитель чаши, с любопытством посмотрел на одну из скамей в центре, где начался непонятный переполох, но вообще-то это его мало занимало. Иногда кому-то из стариков, которых посетил Святой Дух, становилось плохо. Только и делов - вывести человека на свежий воздух.
Мне кажется, что тут содержится некий намек на то, что это за цифра. В тексте названы Хиросима и Нагасаки, города, разрушенные атомными бомбами. Может быть, ключ связан с количеством человеческих жертв, оценочной суммой нанесенного ущерба в долларах… - Она замолчала, снова вчитываясь в текст. - Слово разница особенно важно.
В руке Хейл сжимал беретту. Вскрикнув, она оторвала взгляд от неестественно выгнутой руки и посмотрела ему в лицо.
