Introduction

Scientific journals are a fundamental tool for the dissemination of evidence-based medicine. The scientific quality of a journal is related to the level of evidence of its publications. The aim of our study is to analyse and quantify changes in the levels of evidence assigned to articles published in the RADIOLOGÍA journal over the last six years.

Material and methods

We evaluated articles published in RADIOLOGÍA from 2018 to 2023. A critical reading of the selected articles was carried out and a level of evidence was assigned using two scales that are specific to the field of radiology (Insights into Imaging and the 2011 Oxford Center Evidence Based Medicine). Pearson residuals were used to establish differences in the level of evidence over the years, with a p-value < .05 being considered statistically significant. The level of agreement between the two scales for assessing levels of evidence was also compared using the Kappa coefficient.

Results

Of the total 404 publications in RADIOLOGÍA from 2018 to 2023, 275 articles were included for analysis. There was evidence of a progressive increase in the level of evidence for the publications, with a peak in 2023, consistently on both scales (P = .043). A Kappa coefficient of 0.92 was obtained in the analysis of agreement between scales (almost perfect agreement).

Conclusion

The level of evidence for publications in the RADIOLOGÍA journal has significantly increased in 2023.

科学期刊是传播循证医学的基本工具。期刊的科学质量与其出版物的证据水平有关。我们研究的目的是分析和量化过去六年在RADIOLOGÍA期刊上发表的文章的证据水平的变化。材料与方法我们评估了2018 - 2023年在RADIOLOGÍA上发表的文章。对选定的文章进行批判性阅读，并使用两种特定于放射学领域的量表（透视成像和2011年牛津中心循证医学）来分配证据水平。使用Pearson残差来确定多年来证据水平的差异，p值<； 0.05被认为具有统计学意义。评估证据水平的两个量表之间的一致性水平也使用Kappa系数进行比较。结果2018 - 2023年RADIOLOGÍA收录404篇论文，共纳入275篇。有证据表明，出版物的证据水平逐渐增加，在2023年达到峰值，在两个尺度上都是一致的（P = 0.043）。量表间一致性分析Kappa系数为0.92（几乎完全一致）。结论2023年RADIOLOGÍA期刊发表文章的证据水平显著提高。

Diastematomyelia, a rare congenital anomaly of the spine, is characterised by the separation of the spinal cord and is often associated with other spinal and cutaneous malformations. Diagnosis is made primarily by prenatal ultrasound and fetal Magnetic Resonance Imaging (MRI). Postnatal evaluation is carried out using Computed Tomography (CT) and MRI, and this is essential for a comprehensive assessment and appropriate treatment planning. Prognosis depends on whether or not neurological symptoms are present, and its severity may correlate with specific radiological findings. Treatment ranges from surgery in symptomatic cases to observation in asymptomatic patients. This article reviews diastematomyelia, providing illustrative images from postnatal CT and MRI to emphasize the importance of carrying out a comprehensive assessment to ensure that the diagnosis is accurate and clinical management is thus appropriately guided.

脊髓纵裂是一种罕见的脊柱先天性异常，其特征是脊髓分离，通常与其他脊柱和皮肤畸形有关。诊断主要是通过产前超声和胎儿磁共振成像（MRI）。使用计算机断层扫描（CT）和MRI进行产后评估，这对于全面评估和适当的治疗计划至关重要。预后取决于是否存在神经系统症状，其严重程度可能与特定的放射学表现有关。治疗范围从有症状患者的手术到无症状患者的观察。本文回顾了脊髓纵裂，提供了产后CT和MRI的说明性图像，以强调进行全面评估的重要性，以确保诊断准确，从而正确指导临床管理。

Objective

To evaluate the accuracy of multidetector computed tomography (MDCT) to select patients with peritoneal carcinomatosis (PC) as candidates for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC), through an analysis of the degree of correlation between the radiological (rPCI) and surgical (sPCI) scores in the PC index.

Methods

Observational, retrospective, single-centre study between 1 May 2014 and 31 May 2018. Calculated rPCI assessed by MDCT was compared with the sPCI using the Concordance Correlation Coefficient (CCC). The Bland-Altman method was used to plot the difference between the two observations against their mean with a confidence interval (CI) of 95%. We assessed whether tumour volume affects the CCC by setting a cut-off point of sPCI at 15 and considering a sensitivity and specificity of rPCI > 20 as a predictor of unresectability.

Results

50 patients underwent surgery. Mean sPCI was 11.8 (9.5) and rPCI was 11.0 (10.2), with a CCC of 0.94 (95% CI: 0.91–0.97). The CCC in the 35 patients with sPCI 20 had a sensitivity of 0.82 (95% CI: 0.68–0.92) and a specificity of 0.40 (95% CI: 0.05–0.85). The positive predictive value was 0.92 (95% CI: 0.80–0.98), while the negative predictive value was 0.20 (95% CI: 0.03–0.56).

Conclusion

MDCT, interpreted by an expert radiologist, is reliable for the selection of patients as candidates for CRS + HIPEC; however, the rPCI value cannot be considered in isolation as a contraindication to full treatment. Greater tumour volume usually leads to a worse concordance between rPCI and sPCI.

目的通过分析腹膜癌（PC）指数中放射学（rPCI）评分与外科（sPCI）评分的相关程度，评价多探测器计算机断层扫描（MDCT）选择腹膜癌（PC）患者进行减胞手术和腹腔内热化疗（CRS + HIPEC）的准确性。方法2014年5月1日至2018年5月31日进行观察性、回顾性、单中心研究。采用一致性相关系数（CCC）将MDCT评估的计算rPCI与sPCI进行比较。使用Bland-Altman方法绘制两个观测值与平均值的差值，置信区间（CI）为95%。我们将sPCI的截断点设为15，并考虑rPCI的敏感性和特异性[gt； 20]作为不可切除性的预测因子，以此评估肿瘤体积是否会影响CCC。结果50例患者接受手术治疗。平均sPCI为11.8 (9.5)，rPCI为11.0 (10.2)，CCC为0.94 （95% CI: 0.91-0.97）。35例spci20患者的CCC敏感性为0.82 (95% CI: 0.68-0.92)，特异性为0.40 （95% CI: 0.05-0.85）。阳性预测值为0.92 (95% CI: 0.80 ~ 0.98)，阴性预测值为0.20 （95% CI: 0.03 ~ 0.56）。结论经放射科专家解释的mdct对CRS + HIPEC候选患者的选择是可靠的；然而，rPCI值不能单独视为全面治疗的禁忌症。较大的肿瘤体积通常导致rPCI和sPCI的一致性较差。

Valvular heart disease is a condition with increasing prevalence. Although the current treatment of choice is still valve repair or replacement surgery, percutaneous treatment techniques are valid alternatives for selected patients. Various non-invasive imaging techniques are currently available which can provide the information needed to select appropriate patients, planning procedures and techniques.

This article reviews the usefulness of cardiac CT to assess patients who are candidates for percutaneous treatment of common valvular diseases. It also reviews the image acquisition protocol and its role in the pre-procedural study, as well as in the detection of the most common complications.

瓣膜性心脏病是一种发病率越来越高的疾病。虽然目前的治疗选择仍然是瓣膜修复或置换手术，但经皮治疗技术对某些患者是有效的选择。目前，各种非侵入性成像技术可以为选择合适的患者、计划手术和技术提供所需的信息。本文综述了心脏CT对经皮治疗常见瓣膜疾病患者的评估作用。它还回顾了图像采集方案及其在术前研究中的作用，以及在检测最常见的并发症。

Arterial spin labelling (ASL) is a magnetic resonance imaging perfusion technique used to study cerebral blood flow. It differs from magnetic susceptibility-based perfusion sequences in that it does not require contrast media, but rather uses the signals emitted by pre-labelled protons. It is useful in the exploration of several different kinds of neurological pathologies including ischaemic stroke, brain tumours, dementia and epilepsy. However, it presents numerous artefacts that radiologists must be familiar with to ensure a correct interpretation of findings.

动脉自旋标记（ASL）是一种用于研究脑血流的磁共振成像灌注技术。它与基于磁化率的灌注序列的不同之处在于，它不需要造影剂，而是使用预先标记的质子发出的信号。它有助于探索几种不同类型的神经病理学，包括缺血性中风、脑肿瘤、痴呆和癫痫。然而，它提出了许多人工制品，放射科医生必须熟悉，以确保正确的解释发现。

Background and objectives

The objective was to test whether the Society for Foetal Urology (SFU) and Urinary Tract Dilatation (UTD) ultrasound classifications for postnatal urinary tract dilatation were able to predict the need for surgical treatment or spontaneous resolution of dilatation.

Materials and methods

Retrospective observational study, involving cases whose first ultrasound scans for congenital hydronephrosis were performed between 2008 and 2011.

Clinical variables were recorded and each case was classified according to the SFU and UTD classifications. Univariate analysis and binary logistic regression were performed to establish which clinical and ultrasound variables were related to the need for surgery or medical/non-surgical resolution of dilatation.

Results

Data was collected on 231 kidneys. Spontaneous resolution of dilatation occurred in 41.5% of cases and 40.2% required surgery at some point.

Age (odds ratio (OR) 1.03) and high degrees of dilatation (P2-P3) in the UTD classification (OR 2.33) were associated with an increased risk of needing surgery, while age (OR 0.95) and high degrees of dilatation (P2-P3) in both the UTD and SFU (3-4) classifications were associated with a lower likelihood of spontaneous resolution (OR 0.23 and 0.27 respectively).

Conclusions

Both the UTD and SFU classifications are good predictors of spontaneous resolution of postnatal urinary tract dilatation, while only the UTD classification is predictive of the need for surgery. Older age at the time of the first ultrasound is associated with a higher risk of needing surgery and a lower likelihood of spontaneous resolution of hydronephrosis.

背景和目的目的是检验胎儿泌尿学学会（SFU）和尿路扩张（UTD）超声分类是否能够预测产后尿路扩张是否需要手术治疗或自行消退。材料与方法回顾性观察研究，纳入2008 - 2011年间首次超声检查先天性肾积水的病例。记录临床变量，并根据SFU和UTD分类对每个病例进行分类。采用单因素分析和二元逻辑回归来确定哪些临床和超声变量与手术或药物/非手术解决扩张的需要有关。结果收集了231个肾脏的数据。41.5%的病例自发消退，40.2%的病例需要手术。年龄（比值比（OR） 1.03）和UTD分类中的高度扩张（P2-P3）（OR 2.33）与需要手术的风险增加相关，而UTD和SFU（3-4）分类中的年龄（OR 0.95）和高度扩张（P2-P3）与较低的自发消退可能性相关（OR分别为0.23和0.27）。结论UTD和SFU分类都能很好地预测产后尿路扩张的自发消退，而只有UTD分类能预测是否需要手术。第一次超声检查时年龄越大，需要手术的风险越高，肾积水自然消退的可能性越低。

Objective

To compare the prognostic impact of the extent of lung disease detected on computed tomography (CT) when assessed visually by an expert radiologist compared to automatically by an artificial intelligence (AI) system in patients with COVID-19 pneumonia.

Material and methods

A retrospective study of patients with clinical suspicion of COVID-19 pneumonia which assessed the extent of lung involvement visually and by AI. Patients were divided into poor (death/ICU) and good (discharge) prognosis groups. Univariate and multivariate analyses (logistic regression) were performed on the variables that demonstrated significant differences between both groups.

Results

Patients with a poor prognosis more frequently had greater lung involvement visually (stages 3-4; 37.5% vs 14.3%; P=.001) and by AI (stages 3-4; 35% vs 6.2%; P<.001). The radiologist-AI agreement correlation coefficient was excellent (0.905; P<.001). High blood pressure (OR 4.26; P 0.001), alterations in levels of creatinine (OR 5.63; P<.001), lactate dehydrogenase (OR 11.69; P<.001) and D-dimer (OR 5.68; P<.001), and the extent of affected lung parenchyma assessed visually (stage 1 vs 4 OR 10.36; P=.001) and by AI (stage 1 vs 4 OR 25; P=.001) were the variables wit the greatest prognostic impact in the univariate analysis. The multivariate analysis models considering the extent assessed visually and by AI did not demonstrate any significant differences (AUC 0.876 vs 0.870; P=.278).

Conclusion

The extent of affected lung parenchyma on CT images demonstrates prognostic value both on their own and in conjunction with clinical factors and blood levels in patients with COVID-19 pneumonia. No significant differences were observed between the radiologist's visual estimate and the AI-based automatic detection system used in this study.

目的比较由放射科专家视觉评估计算机断层扫描（CT）检测肺部疾病程度与人工智能（AI）系统自动评估肺部疾病程度对COVID-19肺炎患者预后的影响。材料与方法对临床怀疑为COVID-19肺炎的患者进行回顾性研究，采用视觉和人工智能评估肺部受累程度。患者分为预后差（死亡/ICU）组和预后好（出院）组。单变量和多变量分析（逻辑回归）对两组之间存在显著差异的变量进行分析。结果预后较差的患者在视觉上（3-4期；37.5% vs 14.3%； P=.001）和AI（3-4期；35% vs . 6.2%； P=.001）的肺部受累程度更高。放射科医师与人工智能的一致性相关系数极好（0.905;P<.001）。在单变量分析中，高血压（OR 4.26， P= 0.001）、肌酐水平的改变（OR 5.63， P= 0.001）、乳酸脱氢酶（OR 11.69， P= 0.001）和d -二聚体（OR 5.68， P= 0.001）以及肉眼评估的肺组织受影响程度（1期vs 4期OR 10.36， P= 0.001）和人工智能（1期vs 4期OR 25期，P= 0.001）是影响预后最大的变量。考虑视觉和人工智能评估程度的多变量分析模型没有显示任何显著差异（AUC 0.876 vs 0.870； P= 0.278）。结论CT图像上肺实质病变程度对COVID-19肺炎患者具有预后价值，并可与临床因素及血药水平相结合。在放射科医生的视觉估计和本研究中使用的基于人工智能的自动检测系统之间没有观察到显著差异。

Therapeutic ultrasound diathermy is a widely available noninvasive method, used to softening scar tissue, resolving edema, and accelerating wound healing. However, there is no consensus regarding the efficacy of this method and there is a lack of information on specific complications. We report three cases of focal bone lesions time-related with physiotherapy using ultrasound diathermy. The first patient presented with lesions in the medial and lateral portions of the distal metaphysis of the right femur, as well as in the proximal metaphysis of the tibia. The second patient presented with lesions in the left ankle. The third patient presented with lesions in the knee, bilaterally. The lesions were characterized by subcortical linear or arc lesions with hypointense signal on T1-weighted imaging and hyperintense signal on T2- and proton-density weighted imaging, similar to osteonecrosis. However theses lesions were distributed in superficial areas, in which the ultrasound is directly applied. All patients reported improvement or resolution of pain after discontinuation of ultrasound diathermy. Therefore, therapeutic ultrasound diathermy may be associated with focal bone lesions. This diagnosis should be considered when superficial bone lesions appear time-related to therapy and in areas not usually affected by osteonecrosis.

治疗性超声透热是一种广泛使用的无创方法，用于软化疤痕组织，解决水肿，加速伤口愈合。然而，对于这种方法的疗效并没有达成共识，也缺乏关于具体并发症的信息。我们报告三例局灶性骨病变时间相关的物理治疗使用超声透热。第一位患者表现为右股骨远端干骺端内侧和外侧部分以及胫骨近端干骺端病变。第二例患者表现为左脚踝病变。第三例患者表现为双侧膝关节病变。病变特征为皮质下线状或弧形病变，t1加权像呈低信号，T2及质子密度加权像呈高信号，类似骨坏死。然而，这些病变分布在浅表区域，超声直接应用。所有患者均报告在停止超声透热治疗后疼痛有所改善或缓解。因此，治疗性超声透热可能与局灶性骨病变有关。当浅表骨病变出现与治疗时间相关的情况时，以及在通常不受骨坏死影响的区域，应考虑这种诊断。
