Abstract
Radiologists have always collected copies of model examples and interesting cases encountered in daily practice to use for teaching purposes. A collection of teaching files is an important resource for medical education and the dissemination of knowledge in radiology. Furthermore, the presence of a radiological teaching file is also a requirement at several universities and tertiary institutions in South Africa and abroad, where radiology postgraduate training is conducted.
 
 The advent of digital radiology and the more widespread use of picture archiving and communication systems (PACS) have led to a unique opportunity to change the way that radiology teaching cases are collected, stored and managed. Traditional teaching file systems are rapidly becoming obsolete and incompatible with the digital environment of modern radiology departments.

Several other innovative ways have been described to create digital teaching files (DTF) systems. One such system uses Advantage Windows workstations (General Electric Medical Systems, Milwaukee, USA) – a tagged image file format (TIFF) file is created from the relevant images and stored on another computer connected to the local network which supports file transfer protocol (FTP), after which such files are manually entered into a database
The advent of digital radiology, RIS/picture archiving and communication systems (PACS) and the resulting transformation of modern radiology departments into a digital environment have led to the traditional teaching file system rapidly becoming obsolete
Summary
Radiologists have always collected copies of model examples and interesting cases encountered in daily practice to use for teaching purposes.[1,2] A collection of teaching files is an important resource for medical education and the dissemination of knowledge in radiology. The advent of digital radiology and the more widespread use of picture archiving and communication systems (PACS) have led to a unique opportunity to change the way that radiology teaching cases are collected, stored and managed. Traditional teaching file systems are rapidly becoming obsolete and incompatible with the digital environment of modern radiology departments.[3,4]. The traditional way in which radiology teaching cases were collected comprised mostly film-based teaching file systems that were compiled and stored in a store room or filing cabinet. With the advent of digital radiology, radiological images are acquired in an inherent digital format, which lends itself to the unique position of digital teaching files (DTF). With a DTF, the selected images and appropriate information are stored electronically and recalled for review on a personal computer
