A small-scale experimental study of breast FNA consultation on the internet using Panoptiq.

Introduction: To test the potential for cytopathology consultation using Panoptiq (ViewsIQ, Richmond, BC, Canada; this is a new type of whole-slide image that is made manually and incorporates video content), we investigated its application in the cytopathological diagnosis of cases that were difficult to diagnose by breast fine-needle aspiration (FNA).

Materials And Methods: Panoptiq files were created from liquid-based cytology slides prepared by the BD CytoRich Red (BD, Franklin Lakes, NJ) method. The slides were prepared from 23 consecutive samples of breast FNA that had been diagnosed as atypical or suspicious by the Hokkaido Cancer Center, Hokkaido, Japan.

Voided urine cytology and low-grade urothelial neoplasia of the bladder: factors that influence the sensitivity.

Introduction: The aims of this study were to show the 10-year results of voided urine cytology (VUC) performed using liquid-based cytology (LBC) with CytoRich Red and to discuss the factors that influence the sensitivity of low-grade urothelial neoplasia (LGUN) of the urinary bladder.

Materials And Method: We calculated the sensitivity of VUC in 421 histologically confirmed cases included in the pathology database of Hokkaido Cancer Center in Japan and studied various factors influencing sensitivity.

Results: The cumulative sensitivity of VUC was 95.

Z-axis video for cytology database is a useful tool for the case presentation prior to the cytology training workshop.

We have built a database on the Internet managing z-axis video for cytology (Zavic), and report on a new style of case discussion supported by the Zavic database. Z-axis video for cytology is a movie file derived from the video recording of a microscopic field with changes in the focus. We used it for the case presentation of EUS-FNA of pancreatic lesions on the Internet prior to a training workshop.

Comparison between a traditional single still image and a multiframe video image along the z-axis of the same microscopic field of interest in cytology: Which does contribute to telecytology?

The limitation of cytologic still images is one of the reasons why telecytology has not met with widespread acceptance by the cytology community. Cytologic still image only displays a single depth of field, and this is a particularly acute problem in cytology where the specimen is often much thicker than a single microscopic depth of focus. In this article, we examine the validity of a "z-axis" video of a microscopic field of interest.
