The Use of Scanning Virtual Microscopy for Pathologist Education Peter M. Banks, M.D. Director of Hematopathology Carolinas Medical Center Charlotte, North Carolina Adjunct Professor of Pathology UNC-Chapel Hill
First CME Course Based onVirtual Microscopy for Cases:Lessons Learned • Historical outline • Course organization • First presentation • Conclusions, recommendations
Historical Timeline • ASCP – over 40 years education courses • 2002 – 2 of 4 mainstay courses in hemepath retired • Fall 2002 – proposal for new course from Banks/Dunphy – comprehensive, based on virtual microscopy for cases • November 2003 case scans due • January 2004 – faculty weekend: scan cropping, rehearsal • February 2004 – debut presentation
Course Concept:Comprehensive Review of Hematopathology by WHO ClassificationHemic and Lymphoid
Logistical Challenges with HemicProcesses for CME Courses: Small Cellular Smear/imprint Preparations - Nonreproducible
Case Scan Gathering • Faculty given 6 month deadline to submit slides for scanning, review for QC. • 70 total cases • Cellular smear preparations (marrow, blood) required 60x oil scans • Tissue sections required 40x scans • Trade-off: large enough scans to be representative, small enough for packages
Case Scan Gathering • File format for registrants’ take-home sets: CD’s (700 MB). How many too many? • Faculty meeting 2nd weekend January - 4 weeks prior to course debut(!) - cropping scans and rehearsing presentations. • Last-minute rescans required for 3 cases: critical areas out of focus • Annotations/coordinates for hard-to-find foci in scans • Master scans submitted for duplication and packaging

Course Debut • Course oversold (85 for 80 capacity) • Introductory explanation of system (20 min) • Demo laptop set-up at back of room • Simultaneous (2-screen) presentations - PowerPoints by lecturer Virtual by assisting colleague • Only 10 of 80 brought laptops • Evaluations: 75% favored virtual over glass slides for cases • Many complained that 2-screen presentation too much, hard to follow
Conclusions - Recommendations • Great advantage realized: any cases can be used no matter how small the sampling • Savings in time, cost for producing glass slide sets; scans more durable • Requires one-time extra effort in selecting field for scan, proofing master scans in detail prior to duplication • Needs faculty rehearsal for facile presentation
Postlude • Subsequent courses based on scanning virtual microscopy cases: PMB AAOMP (San Antonio 2006 - through 2009) ASCP Pulmonary Pathology (A. Churg) (first offering 2006) USCAP Specialty conferences and some short courses beginning 2006
