Video Summary

In this video, Dr. Steve Cho discusses the use of intraoperative imaging in pituitary surgery. He explains that the goal of tumor resection is to maximize removal while minimizing neurological damage. Traditional methods, such as visual and tactile sensations, can be inaccurate in distinguishing between tumor and healthy tissue. Dr. Cho presents an alternative technique called intraoperative fluorescence-guided surgery, specifically using near-infrared dyes. By injecting a higher dose of a dye called ICG and imaging the tumor 24 hours later, the technique can distinguish tumor retention from non-tumor tissue. Dr. Cho summarizes the results of their research, showing improved sensitivity and specificity in detecting pituitary adenomas. They plan to further study this technique and develop new targets for targeted dyes. This summary is based on the transcript of a video presentation by Dr. Steve Cho.
