Abstract: | The aim of this study was to assess the image display of a web-based teleradiology system that uses a common web browser and
has no need of proprietary applets, plug-ins, or dedicated software for DICOM display. The teleradiology system (TS) is connected
to the Internet by ADSL and to radiological modalities using the DICOM standard with TCP/IP. Images were displayed on a PC
through Internet connection with the remote TS using a common web browser. MS lesion number and volume in T1- and T2-weighted
images (T1w and T2w, respectively) of 30 brain MR studies were quantified using both the TS and a conventional software. Wilcoxon
signed ranks test and intraclass correlation coefficient (ICC) were used to assess the variability and concordance between
intra- and inter-observer and TS and conventional DICOM viewer, setting significance at p < 0.05. No significant differences in T1w and T2w volumes between the TS and the conventional software were found by either
operator. The ICC results showed a high level of inter-operator agreement in volume estimation in T1w and T2w images using
the two systems. Quantitative assessment of MS lesion volumes in T1w and T2w images with a user interface of a teleradiology
system that allows the consultation by means of a common web browser, without the need for proprietary plug-ins, applets,
or dedicated software for DICOM display showed no significant differences from, and almost complete agreement with, conventional
DICOM viewers. |
