Interactive web-based radiology teaching file.

This multimedia radiology teaching file was developed for medical students, residents, physicians, and researchers to present teaching components related to clinical studies. Patient studies are used to create teaching cases, user can also create lecture series and custom presentations (catalogs) by linking related text and images. The user is able to make and preserve his/her own notes related to reviewed information. From the computer workstation, the user can perform search our case library by American College of Radiology (ACR) codes, keywords, modalities, or text. Results are presented in custom pages and include text lists, thumbnails lists, rescaled images, and full-size images. Text can be easily printed in custom format or exported to an ASCI file. To preserve the privacy of the student, access to our database is granted to the web browser by log-in panel. Image and text can be imported from Digital Imaging and Communications in Medicine (DICOM)-compatible devices or entered by using web forms. In conclusion, we developed a multifunctional interactive teaching environment accessible for multiplatform internet users.

"Robo-Rad": an inexpensive user-friendly multimedia report system for radiology.

BACKGROUND AND PURPOSE: The complex information obtained by CT, MR, and ultrasound examinations is often difficult to convey with a written report. Today's multimedia computer technology provides a medium within which the audio and the visual components of a radiologic consultation can be made available simultaneously, with the projected capability of remote access from any personal computer. A system was developed to run on low-end computer systems with image quality adequate for reporting purposes and prudent memory management (each report occupies < 4 MB). With this system-"Robo-Rad"-the image and radiologist are recorded simultaneously while he or she describes and points out (with a mouse) areas of interest. This dynamic report, along with patient data, can be retrieved and viewed by the consulting physician at his/her convenience using a low-end PC or Macintosh computer. MATERIALS AND METHODS: To assess the clinical utility of Robo-Rad, survey responses were solicited from clinical physicians at the Penn State University Hospital (41.5% faculty/fellows, 31.7% residents, 11.8% medical students, 2% clinical nursing; n = 101) during a hands-on demonstration using studies of 35 consecutive inpatients whose CT scans had been dictated into the system. RESULTS: In an average week, the surveyed professionals ordered 3.2 +/- 3.0 CT studies, reviewed 3.8 +/- 3.0 CTs, spent 1.5 +/- 2.0 hours locating Ct studies, and discussed 2.3 +/- 1.9 CT cases with a radiologist. The average time spent discussing a single CT case with a radiologist was reported as 9.4 +/- 5.9 minutes. On a five-point rating scale (1 = not at all to 5 = very much so), respondents indicated that the Robo-Rad report was helpful (4.3 +/- 0.7) and provided clinically important information that would be difficult to convey with current dictation systems (4.2 +/- 0.8). Desire to discuss the case with a radiologist in addition to viewing the Robo-Rad report scored 3.2 +/- 1.0. If such a system were readily available, 91.8% of the respondents indicated that they would use it in addition to the currently available written report and audio dictation system, and 96.6% would use it instead of the current system. Local area network and modems were the modalities of highest interest for remote access (69.3% and 44.6%, respectively). CONCLUSIONS: Judging by these data, the Robo-Rad system would be of benefit to clinicians. It provides a user-friendly, low-cost multimedia radiology report utilizing readily available technology to improve radiologist-clinician communication.
