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.",[58],"Thyroidectomy","2025-11-25",{"date":61,"type":62},"2025-12-03","ACTUAL",{"date":64,"type":62},"2023-06-13",{"date":66,"type":54},"2026-10",{"name":5,"class":6},1]
