Due to the severity of their disease, palliative care patients often present complex clinical symptoms and complaints like pain, shortness of breath, nausea, loss of appetite, and fatigue. Solely relying on the information available from the history and physical examination often causes uncertainty among palliative care physicians regarding treatment decisions during home visits, potentially leading to unnecessary hospitalizations or transfer to cross-sectional imaging in radiological practices. A rational approach is essential to avoid diagnostic aggressiveness while still providing the imaging information required for optimal palliative care. Bedside use of handheld ultrasound (HHUS) has the potential to expand the diagnostic and therapeutic spectrum in the case of symptom exacerbation but is still underutilized. In this review, we evaluate the potential uses of HHUS in home care settings to provide a more accurate diagnosis of the most common symptoms in palliative patients and to guide bedside interventions such as bladder catheterization, thoracentesis, paracentesis, venous access, and regional anesthesia. Specific training programs for ultrasound in palliative care are currently not available. Adequate documentation is warranted but fraught with technological and privacy issues. Expert supervision and quality assurance are necessary. Despite its limitation and challenges, we suggest that HHUS leads to improved clinical decision-making, expedited symptom relief, and reduced complications without burdening of the patient and costly transfer to hospital or specialty consultations.

由于病情严重,姑息治疗患者经常出现复杂的临床症状和主诉,如疼痛、呼吸短促、恶心、食欲不振和疲劳。单纯依赖病史和体格检查的信息往往会导致姑息治疗医生在家访时对治疗决策的不确定性,可能导致不必要的住院治疗或在放射实践中转移到横断面成像。一个合理的方法是必不可少的,以避免诊断侵袭性,同时仍然提供最佳姑息治疗所需的影像信息。床边使用手持式超声(HHUS)有可能在症状恶化的情况下扩大诊断和治疗范围,但仍未得到充分利用。在这篇综述中,我们评估了hus在家庭护理环境中的潜在应用,以提供对姑息治疗患者最常见症状的更准确诊断,并指导床边干预措施,如膀胱置管、胸腔穿刺、穿刺外穿刺、静脉通路和区域麻醉。目前还没有专门的超声姑息治疗培训项目。充分的文档是必要的,但充满了技术和隐私问题。专家监督和质量保证是必要的。尽管存在局限性和挑战,但我们认为,HHUS可以改善临床决策,加快症状缓解,减少并发症,而不会给患者带来负担,也不会花费高昂的转院费用或专科会诊。

In this study we propose a model for building a holographic ultrasound microscope. In this model two mobile phones are first connected by waves and techniques like the WhatsApp waves. If the mobile phones are close to each other, their inductors and speakers become entangled, they exchange electromagnetic and sound waves, and they vibrate many times with each other. Objects placed between two mobile phones change the sound waves and electromagnetic waves and appear as holographic images within the inductors and also on the plastic of the speakers. To see these images, a hologram machine is built from a room of plastic, one or two magnets, iron particles, and sound producers. Holographic waves change the magnetic field within the hologram machine and move the plastic and iron particles. These objects take the shape of waves and produce holographic images. To see microbes, one can send a weak current to a container of microbes and then connect it to an amplifier. The weak current takes the shape of the microbes and is amplified by one strong amplifier. Then this current goes to the mobile phone and sound card and, after passing some stages, is sent to the second mobile phone. In the second mobile phone, the sound wave is amplified by speakers and transmitted to the hologram machine. Consequently, particles within this machine move and produce big holographic images of the microbes.

在这项研究中,我们提出了一个全息超声显微镜的模型。在这种模式中,两部手机首先通过wave和WhatsApp wave等技术连接起来。如果手机彼此靠得很近,它们的电感器和扬声器就会纠缠在一起,它们会交换电磁波和声波,并且它们会相互振动很多次。放置在两部手机之间的物体会改变声波和电磁波,并在电感器和扬声器的塑料上以全息图像的形式出现。为了看到这些图像,全息影像机是由一间由塑料、一两个磁铁、铁粒子和声音发生器组成的房间组成的。全息波改变全息机内的磁场,移动塑料和铁颗粒。这些物体呈现波浪的形状,并产生全息图像。为了观察微生物,人们可以向装有微生物的容器输送微弱电流,然后将其连接到放大器上。弱电流呈微生物的形状,并被一个强放大器放大。然后,这个电流进入手机和声卡,经过一些阶段后,被发送到第二部手机。在第二个移动电话中,声波被扬声器放大并传输到全息机。因此,机器内的粒子移动并产生微生物的大全息图像。

Purpose Continuous wave Doppler ultrasound is routinely used to detect cardiac valve stenoses. Vector flow imaging (VFI) is an angle-independent real-time ultrasound method that can quantify flow complexity. We aimed to evaluate if quantification of flow complexity could reliably assess valvular stenosis in pediatric patients. Materials and Methods Nine pediatric patients with echocardiographically confirmed valvular stenosis were included in the study. VFI and Doppler measurements were compared with transvalvular peak-to-peak pressure differences derived from invasive endovascular catheterization. Results Vector concentration correlated with the catheter measurements before intervention after exclusion of one outlier (r=-0.83, p=0.01), whereas the Doppler method did not (r=0.49, p=0.22). The change in vector concentration after intervention correlated strongly with the change in the measured catheter pressure difference (r=-0.86, p=0.003), while Doppler showed a tendency for a moderate correlation (r=0.63, p=0.07). Conclusion Transthoracic flow complexity quantification calculated from VFI data is feasible and may be useful for assessing valvular stenosis severity in pediatric patients.

目的常规应用连续波多普勒超声检查心脏瓣膜狭窄。矢量流成像(VFI)是一种与角度无关的实时超声成像方法,可以量化流动的复杂性。我们的目的是评估流量复杂性的量化是否可以可靠地评估儿科患者的瓣膜狭窄。材料与方法对9例经超声心动图证实的儿童瓣膜狭窄患者进行研究。将VFI和多普勒测量值与有创血管内插管引起的经瓣膜峰对峰压差进行比较。结果排除1个异常值后,载体浓度与干预前导管测量值相关(r=-0.83, p=0.01),而多普勒法无相关性(r=0.49, p=0.22)。干预后载体浓度的变化与测得导管压差的变化呈强相关性(r=-0.86, p=0.003),多普勒呈中等相关性(r=0.63, p=0.07)。结论利用VFI数据定量计算经胸血流复杂性是可行的,可用于评估儿童瓣膜狭窄的严重程度。

Purpose A semantic feature-based reporting proforma for intraoperative ultrasound findings in brain tumors was devised to standardize reporting. It was applied as a pilot study on a cohort of histologically confirmed high-grade supratentorial gliomas (Grade 3 and 4) for internal validation. Materials and Methods This intraoperative semantic ultrasound proforma was used to evaluate 3D ultrasound volumes using Radiant DICOM software by 3 surgeons. The ultrasound semantic features were correlated with histological features like tumor grade, IDH status, and MIB index. Results 68 patients were analyzed using the semantic proforma. Irregular crenated was the most common margin (63.2%) and lesions were heterogeneously hyperechoic (95.6%). Necrosis was commonly seen and noted as single (67.6%) or multiple (13.2%) in over 80% cases. A separate perilesional zone, which was predominantly hyperechoic in 41.8% and both hypo and hyperechoic in 12.7%, could be identified in 54.5% of cases. Grade 4 tumors were more likely to have an irregular crenated margin (71.2%) with a single large area of necrosis, while Grade 3 tumors were likely to have smooth (31.3%) or non-characterizable margins (31.2%) with no or multiple areas of necrosis. IDH-negative tumors were more likely to have a single large focus of necrosis. Among the GBMs (52 cases), MIB labelling index of>15% was associated with poorly delineated, uncharacterizable margins, when compared with MIB labelling index<15% (23.5 vs. 0%), (p=0.046). Conclusion A detailed semantic proforma was developed for brain tumors and was internally validated. A few ultrasound sematic features were identified correlating with histological features in high-grade gliomas. It will require further external validation for refinement and acceptability.

目的设计一种基于语义特征的脑肿瘤术中超声结果报告格式,以规范报告。它被应用于一组组织学证实的高级别幕上胶质瘤(3级和4级)的初步研究,以进行内部验证。材料与方法3位外科医生采用术中语义超声形式,利用Radiant DICOM软件对三维超声体积进行评估。超声语义特征与肿瘤分级、IDH状态、MIB指数等组织学特征相关。结果对68例患者进行语义形式分析。不规则圆齿是最常见的边缘(63.2%),病变呈异质高回声(95.6%)。坏死常见于单发(67.6%)或多发(13.2%),占80%以上。在54.5%的病例中可以发现一个单独的病灶周围区,41.8%的病例以高回声为主,12.7%的病例低回声和高回声并存。4级肿瘤更可能有不规则的圆齿状边缘(71.2%),伴有单个大面积坏死,而3级肿瘤可能有光滑的边缘(31.3%)或非特征性的边缘(31.2%),没有或多个坏死区域。idh阴性肿瘤更可能有单个大病灶坏死。与MIB标记指数相比,在52例GBMs中,>15%的MIB标记指数与描述不佳、无法表征的边缘相关。结论:为脑肿瘤开发了详细的语义形式,并进行了内部验证。在高级别胶质瘤中发现了一些与组织学特征相关的超声语义特征。它将需要进一步的外部验证以进行细化和可接受性。

Purpose Pheochromocytoma (PCC) and adrenocortical carcinoma (ACC) are two rare endocrine diseases. Early diagnosis is crucial to significantly reduce morbidity and mortality. In this study, we used endoscopic ultrasound (EUS) for high-resolution imaging to investigate the endosonographic morphology pattern of PCC and ACC. Materials and Methods This retrospective cohort study included 58 PCC/ACC lesions diagnosed by EUS imaging at two tertiary care centers between 1997 and 2015. The following groups were defined by histology or by the presence of a pheochromocytoma-associated syndrome without histological proof: bPCC (benign PCC), mPCC (malignant PCC), and ACC. Results In our cohort, mPCC tended to be larger at the time of diagnosis (n=5; 39.9±41.9 mm) than bPCC (n=46; 27.3 ±20.8 mm, P=0.548). ACC lesions were significantly larger (n=7; 50.6±14.8 mm) than bPCC and mPCC (n=51; 28.5±23.3 mm, P=0.002). In EUS, bPCC and ACC lesions frequently appeared to have a round shape and nodular structure. bPCC and ACC tended to be more hyperechoic (P=0.112 and P=0.558, respectively) and heterogeneous (P=0.501 and P=0.098, respectively) than mPCC. Compared to PCC, ACC did not show high hyperperfusion (P=0.022). In contrast to adenoma, all tumor entities showed hypo-/anechoic areas within the tumor (P<0.05). Conclusion No significant differences in EUS morphology were found to reliably distinguish benign from malignant PCC and ACC lesions. However, EUS may be a reasonable alternative or complementary method to conventional imaging techniques for the early detection of these tumor entities.

目的嗜铬细胞瘤(PCC)和肾上腺皮质癌(ACC)是两种罕见的内分泌疾病。早期诊断对于显著降低发病率和死亡率至关重要。在这项研究中,我们使用超声内镜(EUS)进行高分辨率成像来研究PCC和ACC的超声形态学特征。材料和方法本回顾性队列研究纳入了1997年至2015年在两个三级保健中心通过EUS成像诊断的58例PCC/ACC病变。根据组织学或有无嗜铬细胞瘤相关综合征而无组织学证据来定义以下组:bPCC(良性PCC)、mPCC(恶性PCC)和ACC。结果在我们的队列中,mPCC在诊断时趋向于较大(n=5;39.9±41.9 mm)比bPCC (n=46;27.3±20.8 mm, P=0.548)。ACC病变明显增大(n=7;50.6±14.8 mm)高于bPCC和mPCC (n=51;28.5±23.3 mm, P=0.002)。在EUS中,bPCC和ACC病变常表现为圆形和结节状结构。与mPCC相比,bPCC和ACC更倾向于高回声(P=0.112和P=0.558)和异质性(P=0.501和P=0.098)。与PCC相比,ACC未出现高灌注(P=0.022)。与腺瘤相比,所有肿瘤实体在肿瘤内均表现为低回声/无回声区(p结论EUS形态学无显著差异,可可靠区分PCC和ACC病变的良恶性。然而,EUS可能是早期发现这些肿瘤实体的一种合理的替代或补充方法,而不是传统的成像技术。

Dear Colleagues, It is a special pleasure to introduce the first issue of Ultrasound International Open in a still difficult year - a year, in which many of us had concerns and clinical tasks reaching far beyond basic or clinical science on ultrasonography (US). Thus, I am delighted to draw your attention to some interesting and important new papers teaching us on various aspects of our every day's US practice.

在一个仍然困难的一年里,我们非常荣幸地介绍第一期《超声国际开放》——在这一年里,我们中的许多人都有远远超出超声基础或临床科学的关注和临床任务(美国)。因此,我很高兴地提请您注意一些有趣而重要的新论文,这些论文教授我们日常美国实践的各个方面。

Duplex ultrasound is a noninvasive and rapid technique that offers information on cerebral vascular hemodynamics in real time, which is very useful in acute stroke. Specifically, the orbital study provides important information on collateralization in severe cases of cervical carotid stenosis, showing an inversion of the ophthalmic artery (OA). Less frequently evaluated, hemodynamic changes in the ophthalmic vein provide information on the presence of arteriovenous malformations or fistulas (Erickson SJ et al. Radiology 1989: 173 (2): 511–516). We report a case of ophthalmic artery and vein inversion simultaneously after mechanical thrombectomy (MT).
双工超声是一种无创、快速的技术,可提供实时的脑血管血流动力学信息,在急性脑卒中中非常有用。具体来说,眼眶研究提供了颈动脉狭窄严重病例侧支的重要信息,显示眼动脉内翻(OA)。眼静脉的血流动力学变化提供了是否存在动静脉畸形或瘘管的信息,但很少被评估(Erickson SJ等)。中华放射学杂志,1997,17(2):511-516。我们报告一例机械取栓术后眼球动静脉同时倒置的病例。

Klebsiella Pneumoniae Liver Abscess Syndrome - A Challenge for Contrast-Enhanced Ultrasound. 肺炎克雷伯菌肝脓肿综合征——造影增强超声的挑战。
IF 3.2 Q3 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING Pub Date : 2021-04-01 Epub Date: 2021-04-20 DOI: 10.1055/a-1471-6907

Invasive liver abscess syndrome (ILAS) is caused by strains of hypervirulent Klebsiella pneumoniae (hvKp) and has emerged as the leading cause of liver abscesses in immuno-competent patients (L.K. Siu et al. Lancet Infect Dis 2012; 12: 881-87). ILAS is frequently associated with metastatic spread including the eyes, lungs, and the central nervous system. The morbidity and mortality of affected patients are increased compared to liver abscesses of other origin, especially in cases with concomitant diabetes mellitus (J. E. Choby et al. J Intern Med 2020; 287(3): 283-300). Immediate diagnosis and early intervention are essential for an optimal outcome. Therefore, ultrasound plays a crucial role if hvKp is suspected. However, experience with the characteristics of such abscesses on contrast-enhanced ultrasound (CEUS) is very limited.

侵袭性肝脓肿综合征(ILAS)是由高毒力肺炎克雷伯菌(hvKp)菌株引起的,并已成为免疫能力患者肝脓肿的主要原因(L.K. Siu等)。《柳叶刀感染病》2012;12: 881 - 87)。ILAS常伴有转移性扩散,包括眼睛、肺和中枢神经系统。与其他来源的肝脓肿相比,受影响患者的发病率和死亡率增加,特别是合并糖尿病的患者(J. E. Choby等)。实习医学杂志2020;287(3): 283 - 300)。立即诊断和早期干预对于获得最佳结果至关重要。因此,如果怀疑hvKp,超声波起着至关重要的作用。然而,在超声造影(CEUS)上对这种脓肿的特征的经验非常有限。
