Deep Learning-based sbORN Diagnostic Model

Recruiting
Conditions
Herpesvirus 4, Human
Nasopharyngeal Carcinoma
Registration Number
NCT06463392
Lead Sponsor
Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University
Brief Summary

Skull-base osteonecrosis (sbORN) is a severe long-term complication of nasopharyngeal carcinoma (NPC) post radiotherapy, which significantly diminish the quality of life, increase the risk of internal carotid artery rupture, and is frequently misdiagnosed as NPC recurrence. Novel diagnostic tools are therefore clinically significant. In this study, the investigators seek to ask if a deep-learning-based model shows a significantly higher sensitivity than radiologists. With a cross-sectional design, the investigators aim to recruit 312 participants in Sun Yat-sen Memorial Hospital, Guangzhou, China that meet the eligibility criteria.
