Introduction

Social Media (SM) has transformed how content is shared, especially in the case of medicine. These platforms allow scientific literature to be shared and discussed. SM extends the reach of these scientific articles independent of their quality. The aim of this study was to discover whether sharing an article from Radiología on X (formerly known as Twitter) impacted its reach by analysing the number of downloads, taking into account the different article sections and types.

Material and methods

We selected articles published in Radiología between 2020 and 2022. The articles were promoted by two X accounts: @SERAM_RX and @RevistaRADIOLO2, and downloads were analysed prior to and following dissemination on X.

Results

A total of 100 articles were examined. There was a significant increase in downloads after dissemination on both X accounts (@SERAM_RX: median 49.50, IQR 18.50–73.50 vs median 76.50, IQR 23.75–19; P < ,001 and @RevistaRADIOLO2: median 43, IQR 13.75–133 vs median 65,50, IQR 20,50–277,50; P < ,001), with no significant differences between the two accounts. Posts from @RevistaRADIOLO2 generated more interactions (views, ‘likes’, reposts; P < ,05). Clinical care articles were downloaded more from @SERAM_RX (@SERAM_RX: median 83, IQR 24–198 vs @RevistaRADIOLO2: median 38, IQR 16–79; P < .045).

Conclusion

Sharing articles on SM increases downloads. SM significantly increases the reach of scientific articles and the number of downloads, highlighting the importance of a solid editorial strategy for these platforms.

社交媒体（SM）已经改变了内容的共享方式，尤其是在医学领域。这些平台允许科学文献被共享和讨论。SM扩展了这些科学文章的影响范围，而不依赖于它们的质量。本研究的目的是通过分析下载数量，考虑到不同的文章部分和类型，发现在X（以前称为Twitter）上分享Radiología的文章是否会影响其影响力。材料和方法我们选择了2020年至2022年期间在Radiología上发表的文章。文章由两个X账号：@SERAM_RX和@RevistaRADIOLO2进行推广，并在X上传播之前和之后分析下载情况。在这两个X账户(@SERAM_RX：中位数49.50,IQR 18.50-73.50 vs中位数76.50,IQR 23.75-19；P & lt;，001和@RevistaRADIOLO2：中位数43，IQR 13.75-133 vs中位数65,50,IQR 20,50 - 277,50；P & lt;，001)，两个账户之间没有显著差异。@RevistaRADIOLO2的帖子产生了更多的互动(浏览量、“赞”、转发；P & lt;05)。临床护理文章从@SERAM_RX下载更多(@SERAM_RX：中位数83，IQR 24-198 vs @RevistaRADIOLO2：中位数38，IQR 16-79；P & lt;.045)。在SM上分享文章可以增加下载量。SM显著地增加了科学文章的传播范围和下载量，突出了这些平台可靠的编辑策略的重要性。

Background and objectives

In scientific studies with medical imaging, it is important that the process involved in selecting the explanatory variables is closely monitored, as this can lead to significant confounding biases in its methodology. The aim of this paper is to explore whether it is feasible to use criteria for causation (such as those outlined by Bradford Hill) when selecting variables in articles published in the journal RADIOLOGÍA.

Material and methods

We selected the July-August issue of Radiología, issue 4 of 2023. Four original articles with sample sizes of at least 100 patients were chosen and their follow-up of causation was analysed.

Results

The criteria of temporality, consistency, coherence, plausibility and analogy were observed. The criteria of specificity, experiment, strength and biological gradient were not consistently applied. The methodological robustness and quality of these studies was also noted.

Conclusion

Bradford Hill's criteria for causation are useful for the selection of variables in medical imaging studies. The most relevant criteria in medical imaging are temporality, consistency, coherence, plausibility and analogy.

背景和目的在医学影像学的科学研究中，密切监测选择解释变量的过程是很重要的，因为这可能导致其方法中的显著混淆偏差。本文的目的是探讨在RADIOLOGÍA期刊上发表的文章中选择变量时，使用因果关系标准（如Bradford Hill所概述的标准）是否可行。材料和方法我们选择了2023年第4期Radiología 7 - 8月刊。选取四篇样本量至少为100例患者的原创文章，并对其因果关系进行随访分析。结果观察到时间性、一致性、连贯性、可信性和相似性标准。特异性、实验性、强度和生物梯度标准应用不一致。这些研究的方法学稳健性和质量也得到了注意。结论bradford Hill的因果标准对医学影像学研究中变量的选择是有用的。医学影像中最相关的标准是时间性、一致性、连贯性、合理性和类比性。

Objective

To demonstrate the feasibility of cardiac magnetic resonance (CMR) cine sequences with compressed-sensing (CS) acceleration in the assessment of ventricular anatomy, volume, and function; and to present a fast CRM protocol that improves scan efficiency.

Methods

Prospective study of consecutive patients with indication for CMR who underwent CS short-axis (SA) cine imaging compared with conventional SA cine imaging. We analysed ejection fraction (EF), end-diastolic volume (EDV), stroke volume (SV), and myocardial thickness. Two blinded independent observers performed the reading. Inter- and intraobserver agreement was calculated for all the measurements. Image quality of conventional and CS cine sequences was also assessed.

Results

A total of 50 patients were included, 22 women (44%) with a mean age of 57.3 ± 13.2 years. Mean left ventricular EF was 59.1% ± 10.4% with the reference steady-state free precession sequences, versus 58.7% ± 10.6% with CS; and right ventricular EF with conventional imaging was 59.3% ± 5.7%, versus 59.5% ± 6.1% with CS. Mean left ventricular EDV for conventional sequences and CS were 166.8 and 165.1 ml respectively; left ventricular SV was 94.5 versus 92.6 ml; right ventricular EDV was 159.3 versus 156.4 ml; and right ventricular SV was 93.6 versus 91.2 ml, respectively. Excellent intra and interobserver correlations were obtained for all parameters (Intraclass correlation coefficient between 0.932 and 0.99; CI: 95%). There were also no significant differences in ventricular thickness (12.9 ± 2.9 mm vs 12.7 ± 3.1 mm) (p < .001). The mean time of CS SA was <40 sec versus 6–8 min for the conventional SA. The mean duration of the complete study was 15 ± 3 min.

Conclusions

Cine CS sequences are feasible for assessing biventricular function, volume, and anatomy, enabling fast CMR protocols.

目的探讨压缩感应（CS）加速心脏磁共振（CMR）序列在心室解剖、体积和功能评估中的可行性；并提出了一个快速的CRM协议，提高了扫描效率。方法前瞻性研究连续有CMR指征的患者行CS短轴（SA）影像与常规SA影像比较。我们分析了射血分数（EF）、舒张末期容积（EDV）、卒中容积（SV）和心肌厚度。两位盲法独立观察者进行了阅读。计算了所有测量结果的观察者之间和观察者内部的一致性。并对常规和CS序列的图像质量进行了评价。结果共纳入50例患者，女性22例（44%），平均年龄57.3 ± 13.2岁。参考稳态自由进动序列左室EF均值为59.1%±10.4%，CS组为58.7%±10.6%；常规影像右室EF为59.3%±5.7%，CS为59.5%±6.1%。常规序列和CS的平均左室EDV分别为166.8和165.1 ml；左室SV为94.5 vs 92.6 ml；右心室EDV分别为159.3 vs 156.4 ml；右心室SV分别为93.6 vs 91.2 ml。所有参数在观察者内和观察者间均具有良好的相关性(类内相关系数为0.932 ~ 0.99；置信区间:95%)。两组心室厚度也无显著差异（12.9 ± 2.9 mm vs 12.7 ± 3.1 mm）（p <； .001）。CS SA的平均时间为40 秒，而常规SA的平均时间为6-8 分钟。完成研究的平均持续时间为15 ± 3 min。结论sciine CS序列可用于评估双心室功能、容积和解剖结构，实现快速CMR方案。

Imaging of pseudoaneurysms: Key diagnostic findings, causes and complications 假性动脉瘤的影像学：主要诊断表现、病因和并发症

Radiologia

Pub Date : 2025-03-01 DOI: 10.1016/j.rxeng.2024.07.002

Pseudoaneurysms are common vascular lesions that result as a complication of endovascular interventions, trauma, surgery, inflammatory and tumour processes. They can originate in thoracoabdominal or peripheral visceral arteries. Computed tomography angiography (CT angiography) is the imaging technique of choice for diagnostic confirmation, assessment of complications and therapeutic planning. Doppler ultrasound is initially used in accessible peripheral arteries. The complications of pseudoaneurysms can be potentially serious, mainly their rupture, so their early diagnosis and differentiation from other pathologies is essential to guide treatment. The objective of this manuscript is to represent the image of the pseudoaneurysm in different locations according to its etiology, as well as to review the imaging techniques, study protocols and diagnostic keys. Its complications will be discussed, paying special attention to those that require an emergent therapeutic attitude.

假性动脉瘤是一种常见的血管病变，是血管内干预、创伤、手术、炎症和肿瘤过程的并发症。它们可起源于胸腹动脉或外周内脏动脉。计算机断层血管造影（CT血管造影）是诊断确认、并发症评估和治疗计划的首选成像技术。多普勒超声最初用于可达的外周动脉。假性动脉瘤的并发症可能很严重，主要是其破裂，因此其早期诊断和与其他病理的区分对指导治疗至关重要。本文的目的是根据假性动脉瘤的病因，介绍假性动脉瘤在不同部位的影像学表现，并对其影像学技术、研究方案和诊断关键进行综述。其并发症将被讨论，特别注意那些需要紧急治疗的态度。

Cryoablation in breast tumours 乳腺肿瘤的冷冻消融

Radiologia

Pub Date : 2025-03-01 DOI: 10.1016/j.rxeng.2023.09.010

L. Graña-López, L. Abelairas-López, A. Villares

Cryoablation is a percutaneous thermal ablation technique developed to destroy focal groups of cells using extreme cold. It is an outpatient and image-guided procedure, performed under local anaesthesia, with typically short recovery times and good outcomes. Percutaneous cryoablation has good success rates for treating breast fibroadenomas. It is used in cases of malignant tumours mainly when a patient refuses surgery or is not considered to be a suitable candidate. Some studies indicate that cryoablation could be as effective and safe as lumpectomy in cases of low-risk early-stage breast cancer. Moreover, some studies have reported a regression of metastatic foci after ablation of a primary tumour thanks to an anti-tumour immune response stimulated by cryoablation. This article describes the technique and its indications with regards to breast tumours according to the existing literature.

冷冻消融是一种经皮热消融技术，利用极冷破坏病灶细胞群。这是一种门诊和图像引导的手术，在局部麻醉下进行，通常恢复时间短，效果好。经皮冷冻消融治疗乳腺纤维腺瘤有良好的成功率。它主要用于恶性肿瘤病例，当患者拒绝手术或被认为不是合适的候选人时。一些研究表明，在低风险的早期乳腺癌病例中，冷冻消融可能与乳房肿瘤切除术一样有效和安全。此外，一些研究报道了由于冷冻消融刺激的抗肿瘤免疫反应，原发肿瘤消融后转移灶的消退。本文根据现有文献介绍了该技术及其在乳腺肿瘤方面的适应症。

Aim

This study aims to evaluate the utility of shear wave elastography (SWE) in identifying synovitis in patients with a history of arthritis within the diagnosis of a defined rheumatological disease.

Materials and methods

We performed B-mode and SWE (ultrasound) on 58 participants divided into two groups: group 1 included 29 patients with confirmed active wrist and/or hand synovitis; group 2 included 29 healthy volunteers without suspicion of synovitis. In a subset of patients (n = 8), joint counts and disease evaluations were performed during the elastography to study the correlation between clinical and radiological findings.

Results

The mean maximum kPa value and the average joint kPa value were significantly different between cases and controls: maximum kPa value for cases was 38.14 ± 35.08 kPa, while for controls it was 4.72 ± 5.93 kPa; average joint value for cases was 29.77 ± 26.07 kPa, while for controls it was 4.17 ± 5.22. The most frequent location for joint effusion in both, cases and controls, was the dorsal radiocarpal joint: 41.4% of controls had a mean kPa value of 7.66 ± 5.39 kPa, while 58.6% of cases had a mean kPa value of 40.61 ± 40.76 kPa (p-value 0.004). kPa values correlated with disease activity measurements in the 8 patients clinically evaluated at the moment of the SWE.

Conclusions

SWE is a promising technique that may have a role in the diagnosis and assessment of synovial inflammatory activity in arthritis.

目的本研究旨在评估剪切波弹性成像（SWE）在确定风湿病诊断中识别有关节炎病史的滑膜炎患者中的应用价值。材料和方法我们对58名参与者进行b超和SWE（超声）检查，分为两组：1组包括29名确诊为活动性腕和/或手滑膜炎的患者；第二组29名无滑膜炎嫌疑的健康志愿者。在一部分患者（n = 8）中，在弹性成像期间进行关节计数和疾病评估，以研究临床和放射学表现之间的相关性。结果患者与对照组的平均最大kPa值和关节平均kPa值差异有统计学意义：患者的最大kPa值为38.14±35.08 kPa，对照组的最大kPa值为4.72±5.93 kPa；患者关节值平均为29.77±26.07 kPa，对照组为4.17±5.22 kPa。关节积液最常见于桡腕关节背，41.4%的对照组平均kPa值为7.66±5.39 kPa， 58.6%的病例平均kPa值为40.61±40.76 kPa （p值为0.004）。在临床评估的8例SWE患者中，kPa值与疾病活动性测量值相关。结论sswe在关节炎滑膜炎症活动性的诊断和评估中具有重要的应用价值。
