The first pedCAT Weight Bearing CT Scientific User’s Meeting recently convened at the 2016 Foot International (EFAS, DAF, I-FAB) in Berlin. The meeting focused on weight bearing cone beam CT (WBCT) technology and the potential applications and challenges it presents.
Look for several interesting items as you watch:
- Professor Martinus Richter’s work included a time workflow study on the use of X-Ray, conventional medical CT, and the pedCAT; the results will surprise you. His study also showed how weight-bearing CT measurements are more accurate than X-Ray measurements.
- Dr. Arne Burssens’ study on hindfoot alignment answered critical questions: How do we identify varus and valgus, how do we accurately measure them, and how can we be sure that the measurements are clinically useful and reproducible?
- Dr. Francois Lintz gives us a sneak peek at a new weight-bearing measurement CT tool that will be available exclusively in CubeVue, pedCAT’s software. It will enable users to measure alignment in three dimensions, and distinguish between normal and pathological cases.
- Dr. Cesar Netto’s study focused on adult acquired flatfoot deformity, comparing measurements on weight bearing CT vs non-weight bearing CT.
- Dr. Michael Wachowsky’s study focused on the use of weight bearing CT with pediatric patients, and asks: With the new weight bearing CT technology, what will be the exact definitions of the measurements?
The challenge created by this new technology is clear: How do we now define what we are measuring, since the current X-Ray methods have just been rendered obsolete?
“We can’t have non-weight bearing CTs and say anything about alignment – that’s over,” concluded Dr. Charles Saltzman. “What do we want to measure, and how do we know what we’re measuring represents reality?”
