Abstract
Printed plain radiographs have traditionally been the method of image transfer between hospitals, but the advent of digital imaging has revolutionised modern day radiology. It is now commonplace for compact discs to be used as the transport media for digital images, the theoretical advantages being ease of transport and storage, integration with PACS systems and the ability to perform image manipulation. However, in our tertiary referral centre for pelvic and acetabular trauma, we noted problems with digital image transfer using this method.
We examined the last 25 compact discs sent to our unit for functionality on 3 separate computers. Only 17/25 discs loaded on all computers, and 2 discs failed to load on any computer. 9 of the remaining 23 discs did not allow image manipulation, and 1 disc would not allow retrieval of all the contained images. 5 of the 23 discs took longer than 5 minutes to retrieve the contained images. In summary, we classed 10 of the 25 discs as acceptable. Patient transfer to our unit was not delayed, but 4 patients underwent repeat CT scans due to incomplete imaging
Digital technology has made great advances into medical imaging. Standardisation using the DICOM format for image creation has attempted to eliminate issues of compatibility, but variation in software used to produce and view images can still vary from these standards. Technical errors in the creation of discs should be eliminated at source, and it is mandatory that referring units check the functionality of discs before they are sent. In this way, the potential for delay to transfer and subsequent repeat exposure to ionising radiation can be avoided.
