The current practice of telecytology for rapid on-site evaluation (ROSE): Practical considerations and limitations

Research output: Contribution to journalReview articlepeer-review


Advances in digital imaging technology and development of high-speed internet has brought a change in ROSE practice from the traditional in-person to remote evaluation. The rapid expansion of image-guided procedures to obtain tissues for diagnosis and ancillary testing has put a huge demand on cytopathologists’ time to perform on-site adequacy assessment. The technology of transmitting digital slide images in real-time via the internet from procedure site that can be viewed remotely and provide preliminary diagnosis, has had a huge impact on the practice of ROSE. Telecytology (TC) has increased the efficiency of cytopathologists, by cutting down on travel time to procedure sites and eliminate the long wait time between procedures/needle passes. It also provides the cytopathologist with the flexibility of covering ROSE procedures occurring at several locations simultaneously. The options and design of TC systems are driven by clinical needs, availability of resources and case volume. A buy-in from stakeholders early in the process, infrastructure planning and information technology (IT) support are critical for the successful implementation of TC. Training of staff, validation study and compliance training should be performed according to established guidelines. There are different TC platforms commercially available in the market today, these include static image sharing, real-time video streaming, robotic microscopy and whole slide imaging (WSI). Additionally, low-cost TC system can be built and designed using equipment that are available off-the-shelf. The intent of this review is to highlight the current practices of TC, the pros and cons of each system are discussed.
