Although artificial intelligence algorithms show promise for ovarian cancer diagnosis, their reliance on specialized engineering knowledge hinders their accessibility. The recent emergence of visual large language models such as GPT-4o has further expanded the potential of AI in this domain.  \nMethods GPT-4o was trained to automatically recognize ovarian lesions, report key computed tomography (CT) features of ovarian lesions, and make a benign or malignant diagnosis based on these features. Radiologists and gynecologic oncologists independently reviewed the GPT-4o reports and evaluated GPT-4o's performance.  \nResults GPT-4o achieved diagnostic accuracies of 80.80%, 79.14%, and 93.33% in the three datasets. Its performance surpassed that of gynecologic oncologist with 10 years of experience but was inferior to that of gynecologic oncologist with 16 years of experience and radiologists with ≥ 7 years of experience. The clinician-rated reliability in detecting the four key CT features was 4.22/5.00 for cyst wall and septum status; 4.24/5.00 for nodular or papillary protrusions; 4.30/5.00 for density and enhancement distribution; and 4.25/5.00 for cystic-solid characteristics. The use of GPT-4o increased the accuracy of radiologist and gynecologic oncologist diagnoses by 1.96% and 10.50%, respectively.  \nConclusions GPT-4o identifies the key CT features of ovarian cancer and achieves promising diagnostic accuracy with high-quality diagnostic evidence.  \nKeywords Ovarian cancer · Artificial intelligence · Large language models · Diagnosis · Medical imaging  \nOvarian cancer is the eighth most common cancer in women and is a significant global health concern, accounting for  \n3.4% of new cancer cases and 4. 8% of cancer-related deaths in 2022.1 Ovarian cancer has the highest mortality rate among all gynecological cancers because patients often present at an advanced stage, as early symptoms are non-specific and reliable early detection biomarkers are  \nShimin Zhang, Qiuyang Hou, Mufei Ding, and Yuming Zhu have contributed equally to this work.  \n* Kexue Deng, MD [dengkexue-anhui@163.com](dengkexue-anhui@163.com)  \n* Jiangdian Song, PhD [song.jd0910@gmail.com](song.jd0910@gmail.com)  \n* Xin Zhou, MD [xzhou@cmu.edu.cn](xzhou@cmu.edu.cn)  \n1 Department of Obstetrics and Gynecology, Shengjing Hospital of China Medical University, Shenyang, Liaoning, China  \n2 Department of Radiology, The First Affiliated Hospital of University of Science and Technology of China (USTC); Division of Life Sciences and Medicine, USTC, Hefei, Anhui, China  \n3 School of Health Management, China Medical University, Shenyang, Liaoning, China  \n4 Department of Radiology, Shengjing Hospital of China Medical University, Shenyang, Liaoning, China  \n5 The First Hospital of China Medical University, Shenyang, Liaoning, China  \n6 School of Intelligent Medicine, China Medical University, Shenyang, Liaoning, China  \nA  \nRadiologists  \nB  \nM B  \nKey features detection and malignancy estimation  \nGUIDE  \nGPT-4o  \nC  \nRadiologists  \nGynecologic oncologists  \n\n|  | R1 | R2 | R3 | G1 | ... |\n| --- | --- | --- | --- | --- | --- |\n| Feature 1 | 4 | 3 | ... | ... | .","cbCaivlTS8cyKhpd","https://ap.wps.com/l/cbCaivlTS8cyKhpd","pdf",1540608,11,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusions\n# Study Context and Clinical Need\n## Importance of Early Detection\n## Diagnostic Gold Standard and Role of CT","[{\"question\":\"What problem does GPT-4o aim to address in ovarian cancer diagnosis?\",\"answer\":\"Early-stage ovarian cancer diagnosis is difficult due to limited biomarkers, and many AI methods are hard to access because they depend on specialized engineering knowledge.
