ABSTRACT
RATIONALE AND OBJECTIVES:
We measured the effect of image data loss on diagnostic accuracy to test the possibility of using a retransmission-free network communication protocol for transferring radiologic images.METHODS:
Mammograms transferred over a simulated network with 0%, 15%, and 25% transmission packet loss were presented randomly to 10 observers who typically read mammograms. Observers reported on the presence or absence of microcalcification clusters and the number of calcifications per cluster.RESULTS:
Performance with 15% loss did not differ from performance with 0% loss. The 25% loss condition resulted in a significant decrease in performance. Accuracy of counting individual microcalcifications was high in all three loss conditions.CONCLUSION:
Up to 15% packet loss can be tolerated without affecting diagnostic performance. These data suggest that in some radiologic applications retransmission-free communication protocols may be useful.
