Expert Radiology Application Softwares Enhance Radiology Diagnosis Contributions And Challenges By A Historical Review of Informetric Analysis From 1991 To 2021

In all areas of medicine, especially in radiology, computers are increasing year by year. Filmless radiology, speech recognition software, electronic application forms, and teleradiology are recent developments that have greatly improved radiologists' performance. This research explores radiology software trends, predictions, and the challenges posed by informatics and historical trend analysis. The rationale behind this research is that information technology (IT) is overgrowing almost every day. We must continuously seek new ways to apply IT to make more use of resources. Consequently, IT becomes increasingly crucial to radiology organizations' innovative thinking, workflow, and business models. This study aimed to analyze all radiology software publications in the Science Citation Index (SCI). From 1991 to July 2021, SCI was used to search for publications systematically. We have also widely used this historical method in radiology software research. The findings and discussions are base on an assessment of trends, predictions, contributions, and challenges in radiology software, and we are exploring radiology software with six evolutionary stages. The gift of this research is that radiology managers realize that the use of new information technologies is closely related to survival in a competitive environment. Radiology companies can review these new technologies to develop more innovative business models and services to improve operational deficiencies.

Software Services Delivered from the Cloud

Picture Archiving and Communication Systems (PACS), alongside Radiological Information Systems (RIS) are nowadays widely disseminated, proven useful, hospital information systems components. The “Région Sans Film” (“Filmless Region”) program was launched in 2009 by the French ministry of health in order to help the generalization to all healthcare structures such as hospitals or general physician practices, of PACS, RIS, and archiving of medical images. It is done by means of a mutualized service platform whom building and running has been entrusted to an industrial consortium. This platform implements the latest technologies of medical image processing and of cloud computing. It is built in order to support service-oriented enterprise architecture composed of one main layer of software services. This natively scalable platform is innovative because it is the first one which contains all the materials for the implementation of all services in the cloud. The corresponding SLA are defined in order to be adaptable to the needs of further health structures which could later join the platform by participating in its mutualized purchasing. The goal is not only to share the costs but also to deliver new images sharing services. New business processes/services around sharing of images such as teleradiology or access to the images produced in hospitals to the general practitioners are defined towards the exercise of real filmless radiology.

Quantification of the subjective labour load of a filmless radiology system by the contingent valuation method: a pilot study

Background: A filmless radiology system, which implements a radiology information system and picture archiving and communication system, brings major changes in the work patterns of radiologists and radiological technologists. The purpose of this study was to prospectively quantify the subjective labour load of a filmless radiology system for radiologists and radiological technologists by the contingent valuation method (CVM) and to evaluate the economic labour value. Methods: The questionnaire survey included 14 radiologists and 46 radiological technologists. There was a 75% effective response rate with a total of 45 respondents. The subjective labour load of a filmless radiology system was quantified by the CVM as willingness to accept (WTA). The double-bound dichotomous choice approach was employed for the questionnaire format for WTA. Logistic regression analysis was used to identify the factors affecting WTA. Results: The median and mean WTA per month for radiologists were estimated to be 82,902 yen ($829) and 46,808 yen ($468), respectively. The median and mean WTA for radiological technologists were estimated to be 15,622 yen ($156) and 16,784 yen ($168), respectively. Logistic regression analysis showed promotional view (i.e., willingness to introduce computerization of medical information) as the only significant factor affecting WTA for radiological technologists (p < 0.05). Conclusions: The change from film-based- to filmless- radiology system would be acceptable providing that medical staff in the department of radiology think their labour changes would yield an increase of satisfaction equivalent to 1,430,000 ($14,300) -1,880,000 yen ($18,800).

Picture Archiving and Communication System for Public Healthcare

For the past 100 years, film has been almost the exclusive medium for capturing, storing, and displaying radiographic images. Film is a fixed medium with usually only one set of images available. Today, the radiologic sciences are on the brink of a new age. In particular, Picture Archiving and Communication System (PACS) technology allows for a near filmless process with all of the flexibility of digital systems. PACS consists of image acquisition devices, storage archiving units, display stations, computer processors, and database management systems. These components are integrated by a communications network system. Filmless radiology is a method of digitizing traditional films into electronic files that can be viewed and saved on a computer. This technology generates clearer and easier-to-read images, allowing the patient the chance of a faster evaluation and diagnosis. The time saved may prove to be a crucial element in facilitating the patient’s treatment process. With filmless radiology, images taken from various medical sources can be manipulated to enhance resolution, increasing the clarity of the image. Images can also be transferred internally within hospital departments and externally to other locations such as the office of the patient’s doctor or medical specialist in other parts of the world. This is made possible through the picture-archiving and communication system (Dreyer, Mehta, & Thrall, 2001), which electronically captures, transmits, displays, and saves images into digital archives for use at any given time. The PACS functions as a state-of-the-art repository for long-term archiving of digital images, and includes the backup and bandwidth to safeguard uninterrupted network availability. The objective of the picture-archiving and communications system is to improve the speed and quality of clinical care by streamlining radiological service and consultation. With instant access to images from virtually anywhere, hospital doctors and clinicians can improve their work processes and speed up the delivery of patient care. Besides making film a thing of the past, the likely benefits would include reduced waiting times for images and reports, and the augmented ability of clinicians since they can get patient information and act upon it much more quickly. It also removes all the costs associated with hard film and releases valuable space currently used for storage. According to Dr. Lillian Leong, Chairman of the Radiology IT Steering Group of the Hong Kong Medical Authroity, a single hospital can typically save up to 2.5 million Hong Kong dollars (approximately US$321,000) a year in film processing cost (Intel, 2007). The growing importance of PACS on the fight against highly infectious disease such as Severe Acute Respiratory Syndrome (SARS) is also identified (Zhang & Xue, 2003). In Hong Kong, there was no PACS-related project until the establishment of Tseung Kwan O Hospital (TKOH) in 1998. The TKOH is a 600-bed acute hospital with a hospital PACS installed for the provision of filmless radiological service. The design and management of the PACS for patient care was discussed in the first edition of this encyclopedia (Tong & Wong, 2005). The TKOH was opened in 1999 with PACS installed. At the beginning, due to immature PACS technologies, the radiology service was operating with film printing. A major upgrade was done in 2003 for the implementation of server clustering, network resilience, liquid crystal display (LCD), smart card, and storage-area-network (SAN) technologies. This upgrade has greatly improved the reliability of the system. Since November 2003, TKOH has started filmless radiology service for the whole hospital. It has become one of the first filmless hospitals in the Greater China region (Seto, Tsang, Yung, Ching, Ng, & Ho, 2003; Tsou, Goh, Kaw, & Chee, 2003).

Picture Archiving and Communication System in Health Care

Radiology is the branch of medicine that deals with the diagnostic and therapeutic applications of radiation. It is often used in X-rays in the diagnosis and treatment of a disease. Filmless radiology is a method of digitizing traditional films into electronic files that can be viewed and saved on a computer. This technology generates clearer and easier-to-read images, allowing the patient the chance of a faster evaluation and diagnosis. The time saved may prove to be a crucial element in the patient’s treatment process. With filmless radiology, images taken from various medical sources can be manipulated to enhance resolution, increasing the clarity of the image. Images can also be transferred internally within departments and externally to other locations such as the office of the patient’s doctor. This is made possible through the picture-archiving and communication system (PACS; Dreyer, Mehta, & Thrall, 2001), which electrsonically captures, transmits, displays, and saves images into digital archives for use at any given time. The PACS functions as a state-of-the-art repository for long-term archiving of digital images, and includes the backup and bandwidth to safeguard uninterrupted network availability. The objective of the picture-archiving and scommunications system is to improve the speed and quality of clinical care by streamlining radiological service and consultation. With instant access to images from virtually anywhere, hospital doctors and clinicians can improve their work processes and speed up the delivery of patient care. Besides making film a thing of the past, the likely benefits would include reduced waiting times for images and reports, and the augmented ability of clinicians since they can get patient information and act upon it much more quickly. The creation of a permanent, nondegradable archive will eliminate the loss of film and so forth. Today, the growing importance of PACS on the fight against highly infectious disease is also identified.

Epilogue

Today’s filmless radiology through PACS provides greater speed and superior image quality. However, when workflow is encumbered by inefficiencies, the benefit to the organization – and ultimately the patients – may not be fully realized. Even with the latest equipment installed, many organizations face delays in report-turnaround time and a backlog of patients waiting for appointments. Diminished security and quality can lead to a variety of problems for filmless radiology facilities or departments, including: • Delay in diagnosis and treatment • Emergency department bottlenecks • Increased length of stay • Patient dissatisfaction • Referring physician dissatisfaction • Potential loss of outpatient business • Loss of revenue • Poor public image
