Gadolinium-DTPA enhanced dynamic MR imaging is a new method for the quantification of portal bloodflow and liver perfusion. In this study we evaluated the validity of this method comparing it with thermodiffusion and dopplerflowmetry in pigs. We found a significant correlation of tissue perfusion between dMRI and thermodiffusion and of portal bloodflow between dMRI and dopplerflowmetry. Partial occlusion of the portal vene was accurately detected by dMRI. Dynamic MRI could become a valuable diagnostic method for the quantification of liver perfusion.

[Computer-based training exemplified by the carotid artery].

The purpose of computer-based training (CBT) is interactive use of multimedia components, such as text, graphics, animation, sound, digital slide shows, and videos. This CD-ROM illuminates different aspects of carotid surgery: cerebrovascular insufficiency, sonographic and neuroradiological diagnostics, indications and results of carotid surgery in the literature, perioperative complications and new developments such as interventional procedures. Digital imaging (60 minutes of video sequences and 250 graphics) especially focus on operative standard procedures (conventional and eversion technique) and alternative methods. CBT is an evolving supplement to improve education programs in vascular surgery.

[Development of a computer-assisted learning program for liver transplantation].

The German Society for Surgery recently decided to rename the "video library" as a "multimedia library", which will include also interactive, nonlinear computerised teachware in surgery. We report on the complex interaction of authors, editor, and the computer-based training laboratory, and the pitfalls with respect to data collection, structure, implementation, and technical aspects of the CD-ROM liver transplantation.

[Development of a multimedia CD-ROM series for improving surgical education and continuing education].

In the past 4 years, the computer-based training laboratory of the Department of Surgery, University of Heidelberg, has developed a multimedia library, the med.LIVE-series. This CD-ROM series contains 5000 multimedia units with information of a uniform structure that comprises 26 CD-ROMs. These modules contribute significantly to the training and education of medical students and doctors. Furthermore, this multimedia library is intended to aid in the development of a database-supported online information system. Authors interested are encouraged to contribute to the series.
