Rationale And Objectives: This study evaluates the performance, cost, and processing time of OpenAI's reasoning large language models (LLMs) (o1-preview, o1-mini) and their base models (GPT-4o, GPT-4o-mini) on Japanese radiology board examination questions.
Materials And Methods: A total of 210 questions from the 2022-2023 official board examinations of the Japan Radiological Society were presented to each of the four LLMs. Performance was evaluated by calculating the percentage of correctly answered questions within six predefined radiology subspecialties.
Article Synopsis
- Portopulmonary hypertension (PoPH) is a serious complication linked to portal hypertension, especially in patients with liver cirrhosis, but is often underdiagnosed due to the variety of symptoms like dyspnea.
- A comprehensive case study highlights the use of advanced imaging techniques, including dual energy CT and pulmonary perfusion imaging, to effectively diagnose PoPH.
- This refined imaging protocol provides a noninvasive, efficient way to evaluate PoPH, complementing standard chest evaluations.
