Summary
Telepathology (TP) is feasible for routine diagnoses, including frozen sections. Despite slightly lower accuracy and longer reading times, this dynamic real-time system shows potential for anatomic pathology.
Area of Science:
- Pathology
- Medical Imaging
- Telemedicine
Background:
- Telepathology (TP) enables remote diagnosis by transmitting microscopic images electronically.
- Assessing the feasibility of real-time TP for routine anatomic pathology diagnoses is crucial for modern healthcare.
Purpose of the Study:
- To evaluate the feasibility of a dynamic real-time telepathology system for light microscopic diagnosis.
- To compare the diagnostic accuracy and reading times of TP versus traditional light microscopy (LM), including frozen sections.
Main Methods:
- Six pathologists reviewed 160 slides (80 frozen sections) using both TP and LM in separate periods.
- Diagnoses were compared against a reference standard, and accuracy was graded.
- Intraobserver agreement and reading times were recorded for both methods.
Main Results:
- Light microscopy (LM) showed higher accuracy (1.68) than telepathology (TP) (1.54).
- No significant accuracy difference was observed between frozen sections and paraffin-embedded tissues.
- Average reading time was longer for TP (6.0 minutes) compared to LM (1.4 minutes), though TP reading time decreased over the study.
Conclusions:
- Telepathology is a feasible method for routine light microscopic diagnosis, even for frozen sections.
- While TP had marginally lower accuracy and longer reading times, its efficiency improved during the study.
- The findings support the integration of TP systems in routine anatomic pathology workflows.
