Capability of GPT-4V(ision) in the Japanese National Medical Licensing Examination: Evaluation Study

Autor: Takahiro Nakao, Soichiro Miki, Yuta Nakamura, Tomohiro Kikuchi, Yukihiro Nomura, Shouhei Hanaoka, Takeharu Yoshikawa, Osamu Abe

Publikováno v: JMIR Medical Education, Vol 10, p e54393 (2024)

BackgroundPrevious research applying large language models (LLMs) to medicine was focused on text-based information. Recently, multimodal variants of LLMs acquired the capability of recognizing images. ObjectiveWe aim to evaluate the image recogniti

Relationship between Thyroid CT Density, Volume, and Future TSH Elevation: A 5-Year Follow-Up Study

Autor: Tomohiro Kikuchi, Shouhei Hanaoka, Takahiro Nakao, Yukihiro Nomura, Takeharu Yoshikawa, Md Ashraful Alam, Harushi Mori, Naoto Hayashi

Publikováno v: Life, Vol 13, Iss 12, p 2303 (2023)

This study aimed to explore the relationship between thyroid-stimulating hormone (TSH) elevation and the baseline computed tomography (CT) density and volume of the thyroid. We examined 86 cases with new-onset hypothyroidism (TSH > 4.5 IU/mL) and 107

On the Simulation of Ultra-Sparse-View and Ultra-Low-Dose Computed Tomography with Maximum a Posteriori Reconstruction Using a Progressive Flow-Based Deep Generative Model

Autor: Hisaichi Shibata, Shouhei Hanaoka, Yukihiro Nomura, Takahiro Nakao, Tomomi Takenaga, Naoto Hayashi, Osamu Abe

Publikováno v: Tomography, Vol 8, Iss 5, Pp 2129-2152 (2022)

Ultra-sparse-view computed tomography (CT) algorithms can reduce radiation exposure for patients, but these algorithms lack an explicit cycle consistency loss minimization and an explicit log-likelihood maximization in testing. Here, we propose X2CT-

Aggressive Cushing’s Disease: Molecular Pathology and Its Therapeutic Approach

Autor: Masaaki Yamamoto, Takahiro Nakao, Wataru Ogawa, Hidenori Fukuoka

Publikováno v: Frontiers in Endocrinology, Vol 12 (2021)

Cushing’s disease is a syndromic pathological condition caused by adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas (ACTHomas) mediated by hypercortisolemia. It may have a severe clinical course, including infection, psychiatric disor
