We are planning to train a deep convolutional neural network based on a larger sample of endoscopic images to develop a model to assist surgeons in detection of PTG during endoscopic thyroidectomy. Furthermore, we would like to train a DCNN to predict blood perfusion based on endoscopic images comparing to indocyanine green fluorescence angiography as reference standard, and assess the performance of DCNN in predicting postoperative hypoparathyroidism.",[56],"Thyroidectomy","2025-11-25",{"date":59,"type":60},"2025-12-03","ACTUAL",{"date":62,"type":60},"2023-06-13",{"date":64,"type":52},"2026-10",{"name":5,"class":6},1]
