| Research Abstract |
We have carried out a training for the pathological technologists on the methods of frozen-sections on telepathology. Consequently, the quality of freezing, cutting and staining of obtained specimens for intraoperative histological exmaminations was improved. As for cytological examinations, the over-staining of nuclei causing a wrong diagnosis of malignancy was mostly decreased. However, the methods of extraction and fixation of the cytological specimens by clinicians still leave much room for improvement.
We have started telepathology practices using real-time and still images with Shobara Red Cross Hospital since the 2nd, October, 2003. The pathological technologists of Shobara Red Cross Hospita prepared frozen sections and sent their real-time images to our laboratory for intra-operative diagnosis. Then, we sent still-images to the operating room and report the diagnosis directly to the operating surgeons. Telepathology using real-time and still images was more useful than that using only still images in the following : (1)diagnosis of surgical margins was extremely easy and accurate due to serial observation on all area of frozen sections, (2)time of diagnosing was more shortened, (3)screening of cytological specimens was possible, (4)details on nuclear and cytoplasmic structures and inside of aggregated cell clusters were able to observed due to adjustment of the depth of a focal point, (5)mental pressure of pathologists to telepathological diagnosis was diminished.
