MedicalResearch.com Interview with:| Dr. Wendy L. Frankel, MD. Kurtz Chair and Distinguished Professor and Dr. Anil Parwani, MD, PhD, MBA, Associate Professor Wexner Medical Center The Ohio State University MedicalResearch.com: What is the background for this work? How does digital pathology differ from traditional H/E specimens?  Is there is different processing method?  Difference in prep time or costs? Response: Traditional pathology involves patient tissue coming to the lab and being processed. The end result is a glass slide with a stained tissue that pathologists use under a microscope. The process in digital pathology is the same, up until the point right after when the glass slide is made. In digital pathology, we put the glass slide under a scanner instead of under a microscope. The scanner creates a large file image that can be reviewed remotely by pathologists around the world. The advantage of digital pathology, and the reason we are doing this at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James), is because when the slide is digitized, the image can be rapidly shared with an expert for review, or another institute that the patient may be going to. In addition, I can look at the image and ask the computer to quantitate different types of features that are present in the sample. While this has historically been done manually with a microscope, it’s been a more subjective process that is open to human error. On top of that, we now have computer programs that allow us to ask very specific questions about the sample. For example, we can ask how many nuclei are in the field, how many of the nuclei show signs of cancer, and the size and color of the nucleus. These programs make the whole diagnostic process more objective and standardized. This is something we just can’t do by looking at a glass slide under a microscope. Finally, you can also use these images for presentations at clinical conferences or for teaching residents, fellows or other pathologists. You now have the means to create an archive of patient slides and have it instantaneously available. (more…)
