Background:

Mobile teleradiology systems offer potential for remote diagnostic interpretation.
Assessing the diagnostic accuracy of novel systems is crucial for clinical adoption.

Purpose of the Study:

To evaluate the diagnostic performance of a web-based mobile teleradiology system using an ultramobile PC (UMPC) for abdominal CT interpretation.
To compare the UMPC system's performance against a standard emergency department clinical monitor.

Main Methods:

A total of 100 abdominal CT examinations (56 appendicitis, 44 normal) were reviewed by four observers.
Observers used both a UMPC display and a DICOM viewer on an LCD monitor.
Diagnostic performance was assessed using receiver operating characteristics (ROC) analysis.

Main Results:

The average area under the ROC curve for the UMPC system was 0.959, and for the LCD monitor was 0.976.
Sensitivity and specificity were similarly high for both display systems.
No significant differences were found between the UMPC and LCD monitor for interpreting abdominal CTs.

Conclusions:

The developed mobile teleradiology system using a UMPC is feasible for abdominal CT interpretation.
The system demonstrates comparable diagnostic performance to standard clinical monitors.
This technology may be valuable for emergency teleconsultation, particularly in diagnosing appendicitis.
