Hypoechoic halo is a typical ultrasound finding in giant cell arteritis (GCA), but it may be a false positive due to arteriosclerosis. Therefore, we focused on the segmental distribution of GCA lesions, defined the luminal irregularity in long-axis images as the string of beads sign, and examined its diagnostic ability. As a result, the C-statistic of hypoechoic halo and string of beads sign was better than that of hypoechoic halo alone (1.00 vs. 0.89). Based on the above, the diagnostic ability of GCA can be improved by adding the string of beads sign to the conventional hypoechoic halo.

低回声光晕是巨细胞动脉炎（GCA）的典型超声检查结果，但它可能是动脉硬化引起的假阳性。因此，我们重点研究了 GCA 病变的节段分布，将长轴图像中的管腔不规则性定义为串珠征，并考察了其诊断能力。结果，低回声晕和串珠征的 C 统计量（1.00 对 0.89）优于单纯低回声晕。综上所述，在常规低回声晕的基础上增加串珠征，可提高 GCA 的诊断能力。

Objective

To evaluate the intra- and interobserver reproducibility of parameters used to determine cardiac morphometry and deformation using FetalHQ in Indian population.

Methodology

Two operators blinded to each other performed FetalHQ analysis independently on 35 normal fetuses of gestational age between 18 + 0 and 37 + 0 weeks and days. Intra- and interobserver correlation coefficient and limits of agreement were ascertained for parameters obtained from HQ analysis.

Results

Excellent reproducibility (ICC > 0.9) was observed for global morphometric parameters. Ejection fraction, stroke volume, stroke volume/kg demonstrated excellent reliability (ICC > 0.9), cardiac output, fractional area change showed a lower correlation (ICC < 0.8), and right and left ventricular global strain showed no correlation. Twenty-four segment sphericity index of left ventricle (LV) and right ventricle (RV) showed low to moderate correlation (LV—ICC 0.48–0.79; RV—ICC 0.43–0.82). Fractional shortening (FS) showed poor intraobserver reliability in RV.

Conclusion

FetalHQ provides reliable estimates of the global cardiac morphometry but not for global cardiac strain. Regional transverse contractility represented by FS has poor correlation in right ventricle, especially in the apical region, possibly due to moderator band. Nevertheless, it is a promising tool which requires technical advancements and validation to improve its accuracy and reliability.

目的评估在印度人群中使用 FetalHQ 确定心脏形态和变形的参数在观察者内部和观察者之间的可重复性：方法：由两名互不知情的操作者对 35 名胎龄介于 18+0 至 37+0 周和天数之间的正常胎儿独立进行 FetalHQ 分析。对 HQ 分析获得的参数确定了观察者内部和观察者之间的相关系数和一致性限值：结果：总体形态测量参数的重现性极佳（ICC > 0.9）。射血分数、每搏量、每搏量/千克显示出极佳的可靠性（ICC > 0.9），心输出量、分数面积变化显示出较低的相关性（ICC 结论：胎儿 HQ 可提供可靠的整体心脏形态估计值，但不能提供整体心脏应变估计值。FS所代表的区域横向收缩力与右心室的相关性较差，尤其是在心尖区，这可能是由于调节带造成的。尽管如此，这是一个很有前途的工具，需要技术进步和验证来提高其准确性和可靠性。

Objective

The current study is a comparative cross-sectional analysis study to determine the thickness and internal structure of the masseter muscle (MM) and anterior temporal muscle (ATM) in patients with bruxism by ultrasonography (USG).

Materials and Methods

A total of 100 patients (36 males, 64 females), 50 with bruxism and 50 without bruxism, aged 20–30 years were included in the study. All patients were investigated with MM and ATM USG. The thickness of the muscles was measured at rest and during clenching and the internal structure at rest was classified as Type I, II, and III. Differences in the internal structure between bruxism and non-bruxism groups were determined using the Chi-square test (p < 0.05).

Results

The most common internal structure in bruxism was Type 2 in MM (74%) and Type 1 in ATM (46%), whereas in non-bruxism, Type 1 in MM (58%) and Type 1 in ATM (80%) were found most frequently. While there was a statistically significant difference in the internal echogenic pattern in the right MM and ATM in bruxism (p < 0.05), no significant difference was observed on the left side (p > 0.05). Bruxism patients had higher rest and clench thicknesses than non-bruxism patients on both sides in MM and ATM, however, this did not result in a statistically significant difference (p > 0.05).

Conclusions

The results obtained showed that the evaluation of internal structure and thickness differences via USG is crucial in understanding the nature of the bruxism process affecting the masseter and ATM, facilitating its clinical diagnosis and leading to its treatment.

研究目的本研究是一项横断面对比分析研究，旨在通过超声波检查（USG）确定磨牙症患者的颌间肌（MM）和颞前肌（ATM）的厚度和内部结构：研究共纳入 100 名患者（男 36 人，女 64 人），其中 50 人有磨牙症，50 人无磨牙症，年龄在 20-30 岁之间。所有患者均接受了 MM 和 ATM USG 检查。测量了静止时和咬紧时的肌肉厚度，并将静止时的内部结构分为 I 型、II 型和 III 型。磨牙症组和非磨牙症组之间内部结构的差异采用卡方检验（P 结果）确定：磨牙症患者最常见的内部结构是 MM 中的 2 型（74%）和 ATM 中的 1 型（46%），而非磨牙症患者最常见的内部结构是 MM 中的 1 型（58%）和 ATM 中的 1 型（80%）。在磨牙症患者中，右侧 MM 和 ATM 的内部回声模式差异有统计学意义（P 0.05）。磨牙症患者两侧MM和ATM的静态和咬合厚度均高于非磨牙症患者，但这并没有造成统计学上的显著差异（P > 0.05）：研究结果表明，通过 USG 对内部结构和厚度差异进行评估，对于了解影响颌间肌和 ATM 的磨牙症过程的性质、促进临床诊断和治疗至关重要。

This article reviews all published articles on the application of superb microvascular imaging (SMI) technique in thyroid related diseases before December 31, 2023. SMI, a recently developed ultrasound imaging modality, could display microvascular information by eliminating clutter and preserving low flow signals. Most studies used SMI to help diagnose malignant thyroid nodules and concluded that SMI performed better than color Doppler imaging and power Doppler imaging. At present, there is no consensus when depicting the morphology of vascularity of thyroid nodules (TNs). This problem may be solved by quantitative SMI which makes it possible to quantitatively evaluate the vascularity of TNs. SMI is also applied to evaluate cervical lymph node or thyroid inflammatory diseases. Although, SMI has some limitations, such as no standard for the normal perfusion patterns, and it has a broad application prospect in the diagnosis and management of thyroid related diseases.

本文回顾了2023年12月31日之前所有发表的关于超微血管成像（SMI）技术在甲状腺相关疾病中应用的文章。SMI是最近开发的一种超声成像模式，它可以通过消除杂波和保留低流量信号来显示微血管信息。大多数研究使用 SMI 帮助诊断恶性甲状腺结节，结论是 SMI 比彩色多普勒成像和动力多普勒成像效果更好。目前，对甲状腺结节（TNs）血管形态的描述还没有达成共识。定量 SMI 可以定量评估 TN 的血管情况，从而解决这一问题。SMI 还可用于评估颈淋巴结或甲状腺炎症性疾病。尽管SMI还存在一些局限性，如没有正常灌注模式的标准，但它在甲状腺相关疾病的诊断和治疗中具有广阔的应用前景。

Effectively managing critically ill septic patients requires careful utilization of imaging techniques. While point-of-care ultrasound (POCUS) is invaluable in the ICU, it faces challenges with conventional transcutaneous ultrasound, especially in obese patients. A 22-year-old obese female presented with abdominal pain and renal dysfunction. Abdominal CT confirmed acute biliary pancreatitis, progressing to respiratory failure. Transesophageal and transgastric ultrasound revealed a pulmonary abscess and peripancreatic collection. Expectant management of the lung abscess and percutaneous drainage of the pancreatic collection led to successful recovery. This case highlights POCUS's pivotal role in timely diagnosis, particularly in severe pancreatitis, showcasing its versatility in critical care.

有效管理脓毒症重症患者需要谨慎使用成像技术。虽然床旁超声（POCUS）在重症监护室中非常宝贵，但它面临着传统经皮超声的挑战，尤其是在肥胖患者中。一名 22 岁的肥胖女性出现腹痛和肾功能障碍。腹部 CT 证实其患有急性胆源性胰腺炎，并发展为呼吸衰竭。经食管和经胃超声波检查发现肺脓肿和胰腺周围积液。对肺脓肿的预期治疗和胰腺积液的经皮引流使患者成功康复。本病例强调了 POCUS 在及时诊断，尤其是重症胰腺炎诊断中的关键作用，展示了其在重症监护中的多功能性。

Pseudoaneurysm is a relatively rare venous disease characterized by increased intravascular pressure leading to the rupture of the venous wall. Blood flows through the rupture into the surrounding loose connective tissue, where it is encapsulated by fibrous tissue, forming a localized hematoma with a communication channel to the venous vessel, thus forming a pseudoaneurysm. Currently, there are few reports on its imaging manifestations both domestically and internationally. This article reports a case of imaging manifestations of pseudoaneurysm of the right internal jugular vein and analyzes its characteristics.

假性动脉瘤是一种较为罕见的静脉疾病，其特点是血管内压力增高导致静脉壁破裂。血液通过破裂处流入周围疏松结缔组织，被纤维组织包裹，形成局部血肿，并与静脉血管有沟通通道，从而形成假性动脉瘤。目前，国内外关于其影像学表现的报道较少。本文报告了一例右颈内静脉假性动脉瘤的影像学表现，并分析了其特点。
