Introduction and objectives

Transabdominal ultrasonography (US) is the technique of choice for pelvis evaluation in pediatric population. The results of studies regarding US findings show a wide variation. The objectives of our study were: to estimate and correlate uterine and ovarian ultrasound measures (longitudinal diameter and volume) with chronological age (CA), breast Tanner stage (TS) and gynecological age (GA); to evaluate presence and size of follicles in patients according to their pubertal stage; and to determine the endometrial length in prepubertal and pubertal girls.

Material and methods

Unicentric, observational, retrospective, analytical study, conducted between 2010 and 2019. Healthy girls between 8.0 and 16.0 years, attended in the department of radiology were evaluated. Breast TS was evaluated and gynecological age was determined. Ultrasounds were performed by a pediatric diagnostic radiospecialist. Uterus length (UL) and ovarian length (OL) were measured; uterus and ovarian volume were calculated (UV and OV). Diameter of the largest follicle and endometrial thickness were measured.

Results

292 patients were analyzed, mean age was 12.5 years (SD: 2.1). A significant correlation was observed between uterine and ovarian measurements with CA, TS and GA (P < .0001). A significant increase in UL and UV is described as the CA intervals increase, also in ovarian measurements. No significant differences in measurements were observed between TS I and II. An increase was evidenced at menarche. In 30.9% of pubertal patients and 11.8% of prepubertal patients showed ovarian follicles. The endometrium was not measurable in 88.24% of the pre-pubertal population and was always measurable in patients with TS IV and V.

Conclusions

Uterine and ovarian measurements increased with CA and ET (except ET I and II). The greatest increase occurred with menarche. Ovarian follicles and endometrium thickness less than or equal to 1 mm were presented in prepubertal patients.

经腹部超声是研究儿童和青少年骨盆的首选方法。对这一人群发表的研究各不相同。我们工作的目的是:测量子宫和卵巢超声变量(纵向直径和体积)与实际年龄(ce)、乳腺鞣革期(ET)和妇科年龄(EG)的相关性;根据患者的青春期阶段评估卵泡的存在和大小，并确定青春期前和青春期女孩的子宫内膜厚度。单中心、观察性、回顾性、分析性研究。我们评估了2010年至2019年在诊断成像办公室就诊的8.0至16.0岁的健康女孩。我们评估了乳房ET，确定了ge。超声检查由一名专门从事儿科诊断放射学和影像诊断的专业人员进行。我们测量了子宫纵向直径(DLU)和卵巢纵向直径(DLO)，并计算了两个体积(VU和VO)。我们测量了最大直径的卵泡和子宫内膜厚度。292例患者进行了分析;平均年龄为12.5岁(平均:2.1岁)。子宫和卵巢测量与EC、ET和EG有显著相关性(p < 0.0001)。在卵巢测量中，随着EC间隔的增加，DLU和VU显著增加。在ET I和ET II之间没有观察到显著差异。一项研究发现，在怀孕期间，女性的月经周期增加了50%，而男性的月经周期增加了50%。30.9%的青春期患者和11.8%的青春期前患者有卵巢卵泡。88.24%的青春期前人群的子宫内膜无法测量，而ET IV和v患者的子宫和卵巢测量均随EC和ET增加而增加(ET I和ET II除外)，增幅最大的是初潮。青春期前患者卵巢卵泡和子宫内膜厚度小于或等于1mm。经腹超声(美国)是儿科人群盆腔评估的首选技术。结果研究有关调查结果显示a wide variation)。我们研究的目的是:估计子宫和卵巢超声测量(纵向直径和体积)与年龄(CA)、乳房鞣革期(TS)和妇科年龄(GA)的关系;根据患者的青春期阶段，评估其卵泡的存在情况和大小;= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(1.5%)水。2010年至2019年进行的单中心观察性回顾性分析研究。对在放射科就诊的8.0至16.0岁健康女孩进行了评估。对乳房进行了评估，并确定了妇科年龄。超声是由儿科诊断放射学家进行的。测量子宫长度(UL)和卵巢长度(OL);= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(1.1%)水。= =地理= =根据美国人口普查局的数据，该县总面积为，其中土地和(1.5%)水。292例患者分析，平均年龄12.5岁(SD: 2.1)。子宫和卵巢测量与CA、TS和GA有显著相关性(P < .0001)。促请增加紫外线UL and is公民as the CA intervals增加,还in ovarian measurements。= =地理= =根据美国人口普查局的数据，这个县的总面积，其中土地和(1.1%)水。这是一个明显的增加。= =地理= =根据美国人口普查，cdp的土地面积为。88.24%的青春期前人群的子宫内膜无法测量，而TS IV和v患者的子宫和卵巢测量均在CA和ET患者中增加(ET I和II除外)。在青春期前患者中，卵巢卵泡和子宫内膜厚度小于或等于1毫米。

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.

Neuroimmunological diseases are a broad heterogeneous group of inflammatory disorders in which damage to the central nervous system occurs as a result of immune system abnormalities that can be caused by various pathogenic mechanisms. This may be produced by the presence of autoantibodies, mediated by cells, triggered by infections and paraneoplastic processes, or have a genetic cause.

Radiologists should be familiar with these diseases and be able to perform a differential diagnosis, as early diagnosis and appropriate treatment with immunotherapy can modify the course of the disease in some cases.

This update has 2 objectives:

Review the most common entities within each group, including demyelinating diseases, autoimmune encephalitis, lupus erythematosus, Rasmussen's encephalitis, and haemophagocytic lymphohistiocytosis.

Describe key imaging features that aid in the differential diagnosis between different entities.

Retinoblastoma (RB) is the most common pediatric ocular malignancy and causes high mortality if left untreated. An accurate diagnosis and prompt treatment are of utmost importance, leading to optimal clinical outcomes. RB treatment has evolved over the years with a paradigm shift from life-saving enucleation to globe- and vision-sparing strategies. Intra-arterial chemotherapy (IAC) has become an essential and effective pillar in the management of RB. It has gained popularity as it is a targeted chemotherapeutic agent infusion technique achieved via superselective ophthalmic artery (OA) catheterisation. This improves tumour treatment and reduces recurrence and systemic side effects. In addition, it is often performed as an outpatient procedure, reducing the need for prolonged hospital stays and improving the overall patient experience. In this review, we discuss the history of IAC as well as its technical evolution, outcomes, potential complications and limitations.

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< 0,001 and @RevistaRADIOLO2: median 43, IQR 13.75–133 vs median 65,50, IQR 20,50–277,50; p < 0,001), with no significant differences between the two accounts. Posts from @RevistaRADIOLO2 generated more interactions (views, ‘likes’, reposts; p< 0,05). Clinical care articles were downloaded more from @SERAM_RX (@SERAM_RX: median 83, IQR 24–198 vs @RevistaRADIOLO2: median 38, IQR 16–79; p< 0.045).

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.

Artificial intelligence is rapidly evolving and its possibilities are endless. Its primary applications in cardiac magnetic resonance imaging have focused on: image acquisition (in terms of acceleration and quality improvement); segmentation (in terms of saving time and reproducibility); tissue characterisation (including radiomic techniques and the non-contrast assessment of myocardial fibrosis); automatic diagnosis; and prognostic stratification. The aim of this article is to attempt to provide an overview of the current situation as preparation for the significant changes currently underway or imminent in the very near future.

The appearance of new-onset liver lesions is frequent during imaging follow-up of oncological patients. Most of these lesions will be metastases. But in the presence of atypical radiological findings, there are other diagnoses to consider. Hepatic abscesses, focal nodular hyperplasia-like in patients treated with platinum salts, or hepatocarcinoma in cirrhotic patients are examples of lesions that may appear in the imaging follow-up and should not be confused with metastases. It is essential to establish the nature of the lesion as this will determine the therapeutic management and might avoid unnecessary invasive procedures. The evaluation of previous radiological studies and the global vision of the patient will be primordial. While liver MRI is mainly the indicated imaging technique for these cases, sometimes a biopsy will be unavoidable. In this article, we will discuss through clinical cases some new-onset liver lesions in oncological patients that generated diagnostic doubts and will explain how to orient the diagnosis.

在肿瘤患者的放射检查中，经常出现肝损伤。虽然大多数是转移性的，但在非典型的放射学表现之前，还有其他诊断需要考虑。肝脓肿、铂盐治疗患者的灶性结节性增生或肝硬化患者的肝癌是这些患者随访中可能出现的病变的例子，不应与转移混淆。确定病变的性质是至关重要的，因为治疗管理将依赖于此，并避免不必要的侵入性手术。之前的放射学研究，以及对患者的整体看法，将是至关重要的，虽然肝脏mri通常是适当的检查，但有时活检是不可避免的。在这篇文章中，我们将通过临床病例处理一些新出现的肝损伤在肿瘤患者，可能产生诊断疑问和如何指导诊断。在肿瘤患者的后续成像中经常出现新的肝损伤。大多数病变都是转移性的。然而，在非典型放射学发现的情况下，还需要考虑其他诊断。肝脓肿、用铂盐治疗的患者的局灶性结节性增生或肝硬化患者的肝癌是在随访成像中可能出现的病变的例子，不应与转移混淆。确定病变的性质是至关重要的，因为这将决定治疗管理，并可能避免不必要的侵入性手术。评估以前的放射学研究和病人的整体视力将是最重要的。虽然肝脏MRI主要是用于这些病例的成像技术，但有时活检是不可避免的。在本文中，我们将通过临床病例讨论肿瘤患者中一些产生诊断怀疑的新发肝损伤，并解释如何引导诊断。
