Introduction

Artificial intelligence models can provide textual answers to a wide range of questions, including medical questions. Recently, these models have incorporated the ability to interpret and answer image-based questions, and this includes radiological images. The main objective of this study is to analyse the performance of ChatGPT-4o compared to third-year medical students in a Radiology and Applied Physics in Medicine practical exam. We also intend to assess the capacity of ChatGPT to interpret medical images and answer related questions.

Materials and method

Thirty-three students set an exam of 10 questions on radiological and nuclear medicine images. Exactly the same exam in the same format was given to ChatGPT (version GPT-4o) without prior training. The exam responses were evaluated by professors who were unaware of which exam corresponded to which respondent type. The Mann-Whitney U test was used to compare the results of the 2 groups.

Results

The students outperformed ChatGPT on 8 questions. The students’ average final score was 7.78, while ChatGPT's was 6.05, placing it in the 9th percentile of the students’ grade distribution.

Discussion

ChatGPT demonstrates competent performance in several areas, but students achieve better grades, especially in the interpretation of images and contextualised clinical reasoning, where students’ training and practical experience play an essential role. Improvements in artificial intelligence models are still needed to achieve human-like capabilities in interpreting radiological images and integrating clinical information.

人工智能模型可以为广泛的问题提供文本答案，包括医学问题。最近，这些模型结合了解释和回答基于图像的问题的能力，这包括放射图像。本研究的主要目的是分析chatgpt - 40与三年级医学生在医学放射学和应用物理实践考试中的表现。我们还打算评估ChatGPT解释医学图像和回答相关问题的能力。材料与方法33名学生以放射学和核医学影像为题编了10道试题。ChatGPT（版本gpt - 40）在没有事先培训的情况下，以相同的格式进行了完全相同的考试。这些考试的回答是由不知道哪一种考试对应哪一种答卷类型的教授来评估的。采用Mann-Whitney U检验比较两组结果。结果学生在8个问题上的表现优于聊天测试。学生的平均期末成绩为7.78分，而ChatGPT的平均期末成绩为6.05分，在学生的年级分布中处于第9百分位。讨论：chatgpt在几个领域表现出色，但学生取得了更好的成绩，特别是在图像解释和情境化临床推理方面，学生的训练和实践经验起着至关重要的作用。在解释放射图像和整合临床信息方面，仍然需要改进人工智能模型，以实现类似人类的能力。

Infection remains the most common cause of non-traumatic acute orbital pathology and a relatively common reason for requesting radiological examinations in the emergency department. Infection can affect any part of the orbit but postseptal involvement most frequently justifies imaging requests, due to its potential severity and associated complications. The differential diagnosis of acute orbital pathology is broad and includes not only infectious entities but also inflammatory and neoplastic conditions. It is important to know how to recognise these entities in order to establish early treatment and avoid serious complications. This article reviews, through case images, orbital pathologies of infectious origin, their potential complications and their differential diagnosis.

感染仍然是非创伤性急性眼眶病理的最常见原因，也是急诊科要求放射检查的一个相对常见的原因。感染可影响眼眶的任何部位，但由于其潜在的严重性和相关并发症，中隔后受累最常需要影像学检查。急性眼眶病理的鉴别诊断是广泛的，不仅包括感染性实体，也包括炎症和肿瘤条件。重要的是要知道如何识别这些实体，以便建立早期治疗和避免严重的并发症。本文回顾，通过病例图像，眼眶病变的传染性起源，其潜在的并发症和鉴别诊断。

Introduction

Osteosarcoma and Ewing sarcoma are the most frequent malignant bone tumours in children. The aim of this study is to characterize clinical and radiological features at presentation of a large cohort of children with these diseases, radiological findings useful to differentiate them and the main prognostic factors.

Material and methods

Retrospective analysis of clinical and imaging findings of 83 children diagnosed and treated of Ewing sarcoma and osteosarcoma in a paediatric hospital during a period of 10 years.

Results

Both tumours showed aggressive radiological features such as permeative or moth-eaten margins, cortical disruption, discontinuous periosteal reaction, intense contrast uptake, tumoral necrosis and soft-tissue component. They differed in their location, osseous matrix and gender predilection. Osteosarcoma occurred more frequently in the metaphysis of long bones (62%) with a blastic appearance (53%). Ewing sarcoma showed a predilection for male patients (71%), occurred in flat bones (42%) and in the diaphysis of long bones (58%) with a lytic appearance (82%). 29% of children presented with metastases at diagnosis, most frequently located in the lungs. Survival rates were 78% in osteosarcoma and 76% in Ewing sarcoma. Metastatic disease, aggressive radiological features and low percentage of tumoral necrosis after neoadjuvant chemotherapy were associated with poor prognosis (P < .05).

Conclusions

Imaging can confidently diagnose malignant paediatric bone tumours in children and may differentiate Ewing sarcoma from osteosarcoma, based on gender, location and appearance of the neoplasm. Metastatic disease, presence of aggressive radiological features and low percentage of tumoral necrosis after neoadjuvant chemotherapy were associated with poor prognosis.

骨肉瘤和尤文氏肉瘤是儿童最常见的恶性骨肿瘤。本研究的目的是描述一大批患有这些疾病的儿童的临床和放射学特征，放射学结果有助于区分它们和主要预后因素。材料和方法回顾性分析某儿科医院10年来诊断和治疗的83例尤文氏肉瘤和骨原性肉瘤的临床和影像学表现。结果两种肿瘤均表现为侵袭性影像学特征，如边缘渗透或虫蛀、皮质破裂、骨膜反应不连续、造影剂摄取强烈、肿瘤坏死和软组织成分。它们在位置、骨基质和性别偏好上存在差异。骨肉瘤多见于长骨干骺端（62%），呈母细胞状外观（53%）。尤因肉瘤以男性患者为主（71%），发生于扁平骨（42%）和长骨骨干（58%），呈溶解状（82%）。29%的儿童在诊断时出现转移，最常位于肺部。骨肉瘤和尤文氏肉瘤的存活率分别为78%和76%。新辅助化疗后的转移性疾病、侵袭性影像学特征和低肿瘤坏死率与预后不良相关(P <；. 05)。结论影像学检查可准确诊断儿童恶性骨肿瘤，并可根据肿瘤的性别、部位和外观区分尤文氏肉瘤和骨肉瘤。新辅助化疗后的转移性疾病、侵袭性影像学特征和低肿瘤坏死率与预后不良相关。

Thoracic pain is the most prevalent symptom in patients with cardiovascular diseases. Diagnosis and patient management are guided by the pain attributes, analytical parameters, and several different imaging modalities. Invasive imaging tests and cardiac magnetic resonance are highly relevant in this context, as set out in the 2023 European guidelines for the management of acute coronary syndromes, the 2023 American guidelines for the management of patients with chronic coronary disease, and the 2021 American guidelines for the evaluation and diagnosis of chest pain. This article focuses on the role that these guidelines attribute to non-invasive cardiac imaging (computed tomography and cardiac magnetic resonance) in the management of both acute and chronic coronary syndromes.

胸痛是心血管疾病患者最常见的症状。诊断和患者管理是由疼痛属性，分析参数和几种不同的成像模式指导。正如2023年欧洲急性冠状动脉综合征管理指南、2023年美国慢性冠状动脉疾病患者管理指南和2021年美国胸痛评估和诊断指南所规定的那样，侵入性成像检查和心脏磁共振在这方面具有高度相关性。这篇文章的重点是这些指南归因于非侵入性心脏成像（计算机断层扫描和心脏磁共振）在急性和慢性冠状动脉综合征管理中的作用。

Background and objectives

The purpose of this study was to investigate perspectives held by radiologists on the use of artificial intelligence (AI) in their day-to-day work and to identify factors limiting its routine implementation.

Materials and methods

Spanish board-certified radiologists and trainees completed an online survey of 21 questions on general information and communications technology (ICT) and AI in radiology. Analysis was carried out for the subgroups of gender, age, and professional experience. Associations with a p-value < 0.05 were considered statistically significant.

Results

A total of 102 radiologists and trainees completed the questionnaire. No significant statistical differences between the age groups or gender were observed. A significant difference was detected in ICT and AI knowledge between age groups, with participants under 40 and those between 40–55 years old demonstrating better ICT knowledge (p< 0.01). The survey results revealed that 77.4% of participants believed that AI represents an opportunity for the radiology profession in the future, while 9.8% believed it would have no impact. Three main practical application areas for AI in radiology were proposed: in screening (23.36%), in image interpretation and reporting (21.17%), and in the requesting of imaging and patient scheduling (14.6%). The biggest concern among the surveyed population was the potential increase in workload.

Conclusions

A positive attitude toward AI was observed among Spanish radiologists, with the majority believing that AI could offer opportunities for the radiology profession in the near future. AI training programmes may further improve its acceptance among professionals.

Introduction

Despite the overall high accuracy of the O-RADS MRI scoring system for characterization of indeterminate adnexal lesions, a non-negligible percentage of adnexal lesions remains indeterminate. Given this, the main objective of this study was to evaluate the value of adding quantitative diffusion-weighted imaging (DWI) to Ovarian-Adnexal Reporting and Data System (O-RADS) MRI to improve the diagnostic accuracy of the scoring system in a cohort of indeterminate adnexal lesions according to International Ovarian Tumor Analysis Group Simple Rules (IOTA-SR).

Methods and material

Seventy-nine women with 81 pelvic lesions classified as indeterminate according to IOTA-SR underwent 3-Tesla MRI with a conventional multiparametric protocol. DWI was quantitatively analyzed. Lesions were surgically removed or followed-up, according to a local protocol. Sensitivity, speciﬁcity, positive and negative predictive values and accuracy were determined for conventional multiparametric MRI and quantitative DWI-derived data.

Results

Twenty masses in 72 patients (27.8%) were malignant. An apparent diffusion coefficient (ADC) cut-off value of 1.30 × 10^-3 mm²/s had 89% sensitivity and 80% specificity for malignancy. Overall, adding quantitative DWI to O-RADS MRI increased the specificity (98.08%, P<.001), positive predictive value (94.12%, P<.001), and accuracy (93.06%, P=.05). In the specific O-RADS MRI score 4 subgroup, an ADC cut-off value of 1.22 × 10^-3 mm²/s had 86% sensitivity and 67% specificity for distinguishing benign from malignant lesions.

Conclusion

In IOTA-SR indeterminate adnexal lesions, quantitative DWI significantly improves the diagnostic performance of conventional multiparametric MRI in all O-RADS MRI score groups.

尽管O-RADS MRI评分系统在诊断不确定的附件病变方面具有很高的准确性，但仍有不可忽略的百分比的附件病变仍然是不确定的。鉴于此，本研究的主要目的是根据国际卵巢肿瘤分析组织简单规则（IOTA-SR），评估在卵巢-附件报告和数据系统（O-RADS） MRI上增加定量弥散加权成像（DWI）的价值，以提高评分系统对不确定附件病变队列的诊断准确性。方法和材料79例经IOTA-SR诊断为不确定骨盆病变的女性，采用常规多参数方案进行3-Tesla MRI检查。定量分析DWI。病变手术切除或随访，根据当地协议。对常规多参数MRI和定量dwi衍生数据的敏感性、特异性、阳性和阴性预测值和准确性进行了测定。结果72例患者中有20个肿块为恶性，占27.8%。表观扩散系数（ADC）截止值为1.30 × 10-3 mm2/s，对恶性肿瘤的敏感性为89%，特异性为80%。总体而言，在O-RADS MRI上添加定量DWI可提高特异性（98.08%，P= 0.001）、阳性预测值（94.12%，P= 0.001）和准确性（93.06%，P= 0.05）。在特定的O-RADS MRI评分4亚组中，ADC截止值为1.22 × 10-3 mm2/s，用于区分良恶性病变的敏感性为86%，特异性为67%。结论在IOTA-SR不确定的附件病变中，定量DWI在所有O-RADS MRI评分组中均显著提高了常规多参数MRI的诊断效能。

This article highlights the role of radiologist Eduardo Amorós Martí (1888-1936) in the use of radioactivity for cancer treatment in Spain during the first third of the 20th century. Following the discovery of radium by the Curies in 1898, Amorós became interested in radiology and established his practice in Alicante. He acquired X-ray and radium equipment, contributing to the development of radiation therapy. He directed the Cancer Pavilion at the Provincial Hospital of Alicante, where he promoted the application of radiation in cancer treatment. Like other historical figures associated with radioactivity, his prolonged exposure deteriorated his health, leading to his premature death in 1936.

这篇文章强调了放射学家Eduardo Amorós Martí（1888-1936）在20世纪前三分之一的西班牙使用放射性治疗癌症中的作用。1898年居里夫妇发现镭后，Amorós对放射学产生了兴趣，并在阿利坎特建立了自己的诊所。他获得了x射线和镭设备，为放射治疗的发展做出了贡献。他领导了阿利坎特省医院的癌症馆，在那里他推广了放射治疗在癌症治疗中的应用。与其他与放射性有关的历史人物一样，他长期暴露在核辐射中，导致健康状况恶化，于1936年英年早逝。
