Disparate computer-based information systems such as hospital information systems (HIS), radiology information systems (RIS), and picture archiving and communication systems (PACS) have been introduced into radiology departments at various times to meet specific operational objectives. Typically, these systems are implemented without an integration strategy. Systems integration, which optimizes integrity of data and labor savings, can be achieved by two general approaches. The first links the HIS to the PACS; the second involves interlinking of the HIS, RIS, and PACS, with the RIS as the central controlling system. Standardization in hardware, operating systems, and data base formats--which will allow true integration--is being addressed nationally and worldwide. Operational issues to resolve include ways to increase network capacity, control of data flow, and strategies for dealing with downtime. In the future, systems integration will enable prefetching, two-way interfaces, interfaces with digital dictation systems, and improved linkages with external digital input devices. 相似文献

Extracorporeal shock wave lithotripsy (ESWL) was performed on 925 patients (1,222 treatments) for 446 calyceal, 345 pelvic, 172 ureteral, and 108 staghorn calculi. ESWL necessitated 6.3 KUB and 1.2 renal ultrasound studies per treatment session. Intravenous urography was required in 6% of patients after ESWL. Percutaneous nephrostomy tube placement was performed by the radiologists in 10% of patients. Procedures related to nephrostomy tube placement included percutaneous nephrolithotripsy, tube changes, nephrostography, and stone fragment irrigations and retrievals. Staghorn calculi treatment with ESWL required the most procedures by radiologists (34% for partial staghorn and 56% for complete staghorn) compared with 3%, 8%, and 11% for calyceal, pelvic, and ureteral stones, respectively. In all, 8,478 radiologic examinations and procedures were performed pertaining to ESWL. This is approximately 35 studies per day. While this number may be high because it represents the early experience of the authors with ESWL, the impact on the radiology department can be substantial. 相似文献

To achieve full implementation of the digital radiology department or of picture archive and communication systems, an efficient digital image archive must be constructed. This paper discusses the use of statistical-caching techniques within an image archive. In addition, the results of computer modeling will be used to demonstrate the advantages of this approach. 相似文献

OBJECTIVE: Patients presume safety in radiologic services, but the potential to do harm exists in every area of imaging. Radiology department personnel need to understand basic regulatory requirements for safety and how to promote and improve safety in the future. CONCLUSION: This article reviews key safety metrics that we think are relevant to radiology and discusses how to define the measures and how we are attempting to translate the metrics into a culture of safety. 相似文献

With an increasing number of storage phosphor computed radiography units being installed worldwide, the evaluation of digital chest radiology is no longer being confined to experimental determinations of adequate imaging variables. There has been a substantial increase in the number of clinically based studies that have compared computed radiography with conventional film radiography. The applications of computed radiography are widening and further developments in dual-energy imaging and scanning equalization radiography have become possible through the use of phosphor storage computed radiography. Computer-assisted diagnosis applied to chest radiography may shortly be revolutionized by artificial intelligence, which is capable of assimilating both radiographic and clinical data. 相似文献

Purpose. To increase the quality of internal and external interactions (patients, clinical colleagues, technicians, radiologists) in a department of radiology. Method. Accompanied by a well-experienced adviser workshops have been performed dealing with different topics like “contact to patients”, “performance of the radiological report and interaction with the referring colleague” or “research and teaching”. A catalogue of different actions was defined to reduce hindrances within the internal and external work-flow. Results. A total number of 53 actions was defined and related to different persons who were responsible for the realisation of the measures within a time interval. Six months after starting the quality management 46 (86%) of the defined actions were realised successfully, and another 4 (8%) measures were still running. There was a moderate increase of satisfaction of the patients and clinical colleagues considering the waiting time. Conclusions. A quality management in a radiological department allows an optimisation of the internal and external interactions. However, the guidance of a well-experienced adviser is as essential as the continuous control of successful finished measures. 相似文献

OBJECTIVE: The objective of this study was to assess the effectiveness of film management in a large urban teaching hospital. SUBJECTS AND METHODS: For 5 days in March 1998, individuals seeking access to imaging studies performed in the radiology department of a large urban hospital were questioned about their activities and were physically followed in an effort to characterize the efficiency and effectiveness of the department in servicing individuals not employed by the department. Activities in the department were recorded, and the times to visit completion and the failure rates were assessed. RESULTS: Of the 381 visitors to the department who were followed, 321 were hospital employees and 186 were physicians. The average total time spent in the department was 4 min, during which 2 min were spent viewing images or obtaining consultation. Physicians were in the department an average of only 7 min with 3 min for consultation and image viewing. During the 381 visits, we monitored 753 separate transactions, 693 of which were completed successfully. We found no instances in which a physician indicated that a patient's treatment would be delayed or altered because of film mismanagement and only one instance in which it was suggested that a study may have to be repeated. CONCLUSION: This study found a high level of efficiency and effectiveness in file room operations. 相似文献

Many administrative technologists find interviewing and management of their departmental personnel and the function of a department of personnel difficult to understand. That can result in the personnel department having total control of radiology personnel. The purpose of this article is to offer supervising technologists insight into personnel management. 相似文献

Networked ICD-9 coding system for a radiology department 总被引:2,自引:0,他引:2
OBJECTIVE. We describe a networked database system to implement a departmental list of International Classification of Diseases, 9th edition (ICD-9) codes for use by reporting radiologists. CONCLUSION. Our system is reliable, easy to use, and has increased coding accuracy and speed. In-house development allowed designing a system to specifically address the needs of the radiology group. The resulting list of codes accurately reflects the current practice environment and grows dynamically to suit changing needs. 相似文献

The authors report the experience achieved at the Stanford University (USA) with a digital radiography system which allows the digitization of the film and of the images collected with photostimulable phosphors. The phosphor is essentially an intensifying screen where a latent image is stored after exposure to X-rays and is extracted by a laser scanning. The images collected with the digitized film and with the phosphor (chest, breast, bone) have been analyzed. The digitized film offers potential diagnostic advantages over the conventional film, because of the contrast manipulation and many other processing options. The possibility to recover the information of overexposed films appears very attractive. The photostimulable phosphors allow to get good quality images, with a consistent reduction of dose and costs. These plates offer the possibility, in the next future, to replace the conventional screen-film systems. 相似文献
