Implementation and day-to-day usage of a client-server-based radiology information system.

Implementation of a second-generation radiology information system (RIS) requires attention to many issues, including work flow, system design, training, consideration for emerging technologies, and support. This presentation covers the issues, and solutions, involved in implementation and subsequent day-to-day usage of a client-server-based RIS tightly integrated with a hospital information system (HIS) using "thin client" software to limit hardware requirements for the client computers. The software and hardware implementation had to be designed for potential enterprise-wide scalability of the RIS for a system involving 11 hospitals. Issues arose regarding initial increased turnaround times, errors in importation of historical data, and problems with implementation of interfaces between the RIS and the billing system and between the RIS and the digital dictation system. Network errors and difficulties in using a thin client implementation had to be overcome. Hierarchical training was implemented, as support was switched from an "on-site" support group to a central Information System Division with responsibility to the entire enterprise.

A picture archiving and communications system featuring multiple monitors using Windows98.

We present an effective approach to manage, review, and distribute Digital Imaging and Communications in Medicine (DICOM) images with multiple monitors using Windows98 (Microsoft Corp, Redmond, WA) that can be implemented in an office-based setting. Computed tomography (CT), magnetic resonance imaging (MRI), and angiographic DICOM images were collected, compressed, and stored using Medweb (Medweb, Inc, San Francisco, CA) software. The Medweb server used the Linux/UNIX operating system on a Pentium 333-MHz processor with 128 MB of RAM. Short-term storage capacity was about 2 weeks with routine usage of an 11-GB hard drive. Images were presented for reading on a dual-monitor Windows98 Pentium display station with 160 MB of RAM using a Medweb/Netscape (Netscape Communications Corp, Mountain View, CA) viewer. There was no significant discrepancy in diagnosis between electronic and conventional film images. Mean reading time for 32 cases was 118 seconds. The Medweb JAVA plug-in viewer loaded the first image within 30 seconds of selecting the case for review. Full uncompressed 16-bit images allowed different window settings to better assess for pathology. Multiple monitors allowed viewing various hanging protocols. Cine viewing was also possible. Key diagnostic images were electronically transmitted to referring physicians. On-call radiologists were able to access images through the Internet. By combining Medweb, DICOM, and web-browser software using desktop personal computers (PCs), an easily accessible picture archiving and communications system (PACS) is available to radiologists and referring physicians. Multiple monitors are easily configured and managed using Windows98. This system can sustain changes and can be extended to provide variable functions using inexpensive PCs.

Dynamic high-resolution sonography of the carpal tunnel.

CTS is an increasingly common condition with symptoms resulting from compression of the median nerve. Although most cases are clinically straightforward, those with confusing clinical pictures or equivocal or contradictory diagnostic studies may benefit from imaging. Although MR imaging has been established as a useful imaging technique for the evaluation of CTS, sonography may be a low-cost alternative. Imaging criteria for the diagnosis of CTS apply to both sonography and MR imaging. Sonographic evaluation of a large series of patients is still necessary to determine the definitive role of sonography in CTS.

Neurobehavioral functioning and magnetic resonance imaging findings in young boxers.

In a prospective investigation of neurobehavioral functioning in young boxers, 13 pugilists and 13 matched control subjects underwent tests of attention, information-processing rate, memory, and visuomotor coordination and speed. The results disclosed more proficient verbal learning in the control subjects, whereas delayed recall and other measurements of memory did not differ between the two groups. Reaction time was faster in the boxers than in the control subjects, but no other differences were significant. Ten subjects in each group were retested 6 months later and exhibited improvement in their neuropsychological performance as compared to baseline measurements. However, there were no differences in scores between the boxers and the control subjects at the follow-up examination or in the magnitude of improvement from baseline values. Magnetic resonance imaging, which was performed in nine of the boxers, disclosed normal findings.
