Introduction

The use of innovative teaching methodologies, such as collaborative work, constitutes a significant change for both teachers and students. This method requires greater autonomy from students, and significantly more effort from both students and teachers due to the importance of careful planning and the monitoring of learning. Thus, this teaching model promotes the development of various skills which include critical thinking and self-management.

Method

We carried out a cross-sectional observational study of a collaborative activity used in several classes in the subject ‘Diagnostic Imaging and Physical Medicine’ in the third year of an undergraduate medicine degree. The students were divided into 13 groups of 8 people, separated using the order of the class list to avoid grouping friends. Each group was given a different clinical case with a radiological image of a bone tumour, and the students were asked to describe it individually at home applying the theory they had been taught in previous ‘Semiology of bone tumours’ classes. Subsequently and autonomously, they then had to describe it to a classmate from the same group. Later, they described it in groups of two and four during class time before the group of eight students finally had to describe it in front of the whole class and try to provide a diagnosis. During the preparatory classes, the teacher went around the groups answering questions. After the final description, the teacher provided feedback. The activity was evaluated through a questionnaire filled out by the students.

Results

The results of the survey reveal the opinions of the students. Overall, they found the methodology to be appropriate, and 60% of those surveyed said that it facilitated the acquisition of knowledge, is an innovative form of self-learning, increased their level of involvement and improved their relationships with their colleagues. Likewise, more than 50% of the participants believe that collaborative work is an appropriate method for their training, providing them with a greater sense of participation.

Conclusion

Collaborative work is found to be an appropriate methodology to improve the acquisition of knowledge. However, it requires greater effort and involvement from both teachers and students, which means that students are not keen on applying it to other subjects. Students consider as a drawback the potential for imbalances of participation.
使用创新的教学方法,如合作作业,对教师和学生都构成了重大变化。这种方法需要学生更大的自主权,由于仔细计划和学习监控的重要性,学生和教师都需要付出更多的努力。因此,这种教学模式促进了各种技能的发展,包括批判性思维和自我管理。方法我们对医学本科三年级“诊断成像和物理医学”课程中几个班级的协作活动进行了横断面观察研究。学生们被分成13组,每组8人,按照班级名单的顺序分开,以避免朋友分组。每一组都有一个不同的临床病例和骨肿瘤的放射图像,学生们被要求在家里单独描述它,应用他们在以前的“骨肿瘤符号学”课上教过的理论。随后,他们必须自主地向同一组的同学描述它。后来,他们在课堂上分成两组和四组进行描述,最后八组学生不得不在全班面前描述并试图提供诊断。在预科课上,老师在小组间轮流回答问题。在最后的描述之后,老师给出了反馈。该活动通过学生填写的调查问卷进行评估。调查的结果揭示了学生们的看法。总的来说,他们发现这种方法是合适的,60%的受访者表示,这种方法有助于获取知识,是一种创新的自学形式,提高了他们的参与度,改善了他们与同事的关系。同样,超过50%的参与者认为协作工作是他们培训的合适方法,为他们提供了更大的参与感。结论协同工作是提高知识获取的有效方法。然而,它需要教师和学生更大的努力和参与,这意味着学生不热衷于将其应用到其他科目。学生们认为学生参与不平衡的可能性是一个缺点。

Introduction

Various studies have explored the concept of diabetes mellitus (DM) as a coronary risk equivalent. However, current evidence does not wholly support this conclusion. This study aimed to ascertain whether DM can be validated as a coronary risk equivalent through stress perfusion cardiac magnetic resonance (stress CMR) imaging.

Material and methods

Three hundred thirty-three patients with and without DM who were referred for stress CMR between 2009 and 2013 were retrospectively reviewed. Images were visually interpreted and classified based on the presence of myocardial ischemia. Survival data and occurrence of major cardiovascular events were recorded and compared.

Results

Of the 333 patients, 139 had DM (133 DM type I y 6 type II), (101 without ischemia, 38 with ischemia) and 194 had no DM (165 without ischemia and 29 with ischemia). A total of 70 events occurred during a median follow-up of 27 months. Diabetic patients without myocardial ischemia had a lower incidence of major cardiovascular events (death any cause, acute coronary syndrome, or need for revascularization) compared with non-diabetic patients with ischemia (16.8% vs. 41.1% respectively, p < 0.001).

Conclusion

Diabetic patients with high cardiovascular risk without ischemia exhibit a more favourable prognosis compared to non-diabetic subjects with high prevalence of obstructive coronary artery disease and ischemia. According to our results, DM may not be considered as equivalent to coronary risk. Patients should be treated individually, given the heterogeneity found in DM population.
各种研究已经探讨了糖尿病(DM)作为冠状动脉危险等同物的概念。然而,目前的证据并不完全支持这一结论。本研究旨在通过压力灌注心脏磁共振(stress CMR)成像确定糖尿病是否可以作为冠状动脉风险当量。材料和方法回顾性分析2009年至2013年间333例有或无糖尿病的患者进行应激性CMR。根据心肌缺血的存在对图像进行视觉解释和分类。记录生存数据和主要心血管事件的发生并进行比较。结果333例患者中,糖尿病139例(1型糖尿病133例,2型糖尿病6例),无缺血101例,有缺血38例,无糖尿病194例(无缺血165例,有缺血29例)。在27个月的中位随访期间共发生了70例事件。无心肌缺血的糖尿病患者的主要心血管事件(任何原因死亡、急性冠状动脉综合征或需要血运重建术)发生率低于无缺血的糖尿病患者(分别为16.8%和41.1%,p <; 0.001)。结论无缺血的糖尿病高危心血管患者的预后优于有阻塞性冠状动脉疾病和缺血的非糖尿病患者。根据我们的研究结果,糖尿病可能不等同于冠状动脉风险。鉴于糖尿病人群的异质性,患者应单独治疗。

Objective

To compare the following rates between women with high breast density and women with low breast density that have participated in a breast cancer screening programme in Spain: recall rate (RR), false positive rate (FPR) and detection rate (DR).

Materials and Methods

We carried out a retrospective observational study in two tertiary hospitals in Barcelona. We included asymptomatic women aged 50–69 years, who attended the breast cancer screening programme between 1 January and 31 December 2022. Mammograms included two bilateral projections and breast density was assessed visually by expert radiologists, following the 5th edition BI-RADS recommendations. RR, FPR and DR were compared between the group of patients with high breast density (ACR-C, ACR-D) and the group with low breast density (ACR-A, ACR-B).

Results

The study included 18,193 women screened in 2022, of which 37.5% (6830 women) had dense breasts. It was noted that the proportion of women with high breast density decreased as age increased. The group of women with dense breasts had a higher RR (5.5% vs. 2.8%) (P-value < .001) and a higher FPR (49.6/1000 vs. 24.8/1000) (P-value < .001) than those with low breast density. Furthermore, the DR for breast cancer was higher for women with dense breasts (5.85/1000 vs. 3.6/1000) (P-value = .013).

Conclusions

High breast density is associated with increased RRs and FPRs in our screening programme. It is also related to a higher breast cancer DR.
目的比较西班牙参加乳腺癌筛查项目的高乳腺密度妇女和低乳腺密度妇女的召回率(RR)、假阳性率(FPR)和检出率(DR)。材料和方法我们在巴塞罗那的两家三级医院进行了回顾性观察研究。我们纳入了在2022年1月1日至12月31日期间参加乳腺癌筛查计划的50-69岁无症状妇女。乳房x光检查包括两个双侧投影,乳房密度由放射科专家根据第5版BI-RADS建议进行视觉评估。比较高乳腺密度组(ACR-C、ACR-D)与低乳腺密度组(ACR-A、ACR-B)的RR、FPR、DR。结果该研究纳入了2022年筛查的18193名女性,其中37.5%(6830名女性)患有致密性乳房。有人指出,乳房密度高的妇女比例随着年龄的增长而下降。乳腺致密组的RR(5.5%比2.8%)(p值 <; .001)和FPR(49.6/1000比24.8/1000)(p值 <; .001)高于乳腺低密度组。此外,乳腺致密的女性乳腺癌的DR更高(5.85/1000 vs. 3.6/1000) (p值 = .013)。结论在我们的筛查方案中,高乳腺密度与RRs和fpr增加有关。它还与较高的乳腺癌DR有关。

Lipomatosis of nerve (LN) is a rare condition characterised by fibroadipose lesions affecting the peripheral nerves. It presents a complex clinical challenge, often associated with macrodystrophia lipomatosa. Various imaging techniques, specifically magnetic resonance imaging (MRI) and ultrasound (US), are crucial for its diagnosis and precise monitoring. On MRI, LN appears as a lesion displacing surrounding structures, presenting as hypointense cable-like nerve bundles. On US, it has a ‘lotus root-like’ appearance. The wide range of clinical presentations of LN and the extensive array of differential diagnoses underscore the need for individualised diagnostic and treatment strategies. The aim of this article is to provide a thorough review of LN through illustrative images.
神经脂肪瘤病是一种罕见的疾病,其特征是纤维脂肪病变影响周围神经。它提出了一个复杂的临床挑战,通常与巨大营养不良性脂肪瘤有关。各种成像技术,特别是磁共振成像(MRI)和超声(US),对其诊断和精确监测至关重要。在MRI上,LN表现为取代周围结构的病变,表现为低信号的索状神经束。在美国,它有一个“莲藕”的外观。LN广泛的临床表现和广泛的鉴别诊断强调了个性化诊断和治疗策略的必要性。本文的目的是通过说明性图像对LN进行全面的回顾。

The FIGO (International Federation of Gynaecology and Obstetrics) classification for the staging of endometrial cancer was updated in 2023. This new classification, based on clinicopathological data, represents a challenge for the radiologist, who needs to know histological data before assigning a prognostic stage to the tumour. This article provides the histopathological information necessary for a better understanding of this FIGO 2023 classification. It also presents explanatory graphs and a comparative study with the previous FIGO classification, highlighting the new features and possible errors that can be made, all with the aim of facilitating the radiologist's work.
FIGO(国际妇产科联合会)对子宫内膜癌分期的分类于2023年更新。这种基于临床病理数据的新分类对放射科医生来说是一个挑战,因为放射科医生在为肿瘤分配预后阶段之前需要了解组织学数据。本文为更好地理解FIGO 2023分类提供了必要的组织病理学信息。它还提供了解释性图表,并与以前的FIGO分类进行了比较研究,突出了新的特征和可能出现的错误,所有这些都是为了方便放射科医生的工作。

It also presents explanatory graphs and a comparative study with the previous FIGO classification, highlighting the new features and possible errors that can be made, all with the aim of facilitating the radiologist's work.</div></div>","PeriodicalId":94185,"journal":{"name":"Radiologia","volume":"67 6","pages":"Article 101620"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145476146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urgent ophthalmic pathology can be grouped into four categories: infectious, traumatic, vascular, and inflammatory. Imaging techniques play a fundamental role in their diagnosis, positioning the radiologist at the forefront when dealing with these entities. CT is usually the technique of choice within the emergency context, with MRI and ultrasound playing a secondary role. Radiologists must be familiar with the main imaging findings of these pathologies to make a rapid and accurate diagnosis that contributes to a positive outcome for the patient. This article reviews orbital anatomy, imaging techniques and protocols that should be employed, as well as key diagnostic clues that every radiologist should know.
紧急眼科病理可分为四类:感染性、创伤性、血管性和炎症性。成像技术在其诊断中起着重要作用,在处理这些实体时,将放射科医生定位在最前沿。在紧急情况下,CT通常是首选技术,MRI和超声波起次要作用。放射科医生必须熟悉这些病理的主要影像学表现,才能做出快速准确的诊断,从而为患者带来积极的结果。本文回顾了眼眶解剖,成像技术和应采用的方案,以及每个放射科医生应该知道的关键诊断线索。
