Clinical monitoring of the parameters of high-resolution ultrasound and magnetic resonance imaging (MRI) in the diagnosis of edema after injection contour plastic. When fillers were detected, hypoechoic avascular structures were found in the soft tissues of the face with blurred contours against the background of infiltrative changes. On MRI the filler was more clearly visualized in the fat suppression mode as a signal section with clear, even contours of certain shapes subcutaneously and supraperiostal. Infiltration changes were characterized by signal amplification and contour blurring.

For the timely detection of pathology, as well as in order to avoid overdiagnosis, it is important to create criteria for diagnosing the pathology of the craniovertebral zone in adults and children, taking into account their anatomical and physiological features. To date, the questions of the optimal method of radiodiagnosis of patients with pathology of the craniovertebral region are insufficiently voluminous and clearly defined. Despite the advantages, cone beam computed tomography is still not widely used in everyday clinical diagnostic practice for the study of the craniovertebral region in the population. The use of the technique of cone beam computed tomography could greatly facilitate radiological diagnosis for the detection of anomalies and pathological conditions of the craniovertebral region.

为了及时发现病理，避免过度诊断，结合成人和儿童的解剖和生理特点，建立颅脑区病理诊断标准是非常重要的。迄今为止，关于颅椎区病变患者放射诊断的最佳方法的问题还不够多，也没有明确的定义。尽管有这些优点，锥束计算机断层扫描仍然没有广泛应用于日常临床诊断实践中，用于研究人群的颅椎区域。锥束计算机断层扫描技术的应用可以极大地促进对颅椎区异常和病理状况的放射诊断。

The results of surgical treatment of 56 patients were analyzed. All patients were undergone on breast-conserving surgery with intraoperative X-ray control on a mammographic digital device.The mean time to complete the study was 10 minutes, which did not significantly affect the duration of the operation.Of the 56 studied preparations after breast-conserving surgery, a positive resection margin (R1) was found in 1 case during a planned histological examination, which is associated with a high X-ray density of the patient’s breast tissue. In 2 cases, positive resection margins (DCIS) were detected, additional excision made it possible to avoid repeated surgical intervention. In 1 case, a false positive result was obtained, which did not negatively affect the results of surgical treatment. There were no false negative results.

对56例患者的手术治疗结果进行分析。所有患者均行保乳手术，术中x线控制在数字设备上。完成研究的平均时间为10分钟，这对手术的持续时间没有显著影响。在研究的56例保乳手术后的准备中，1例在计划的组织学检查中发现阳性切除缘(R1)，这与患者乳腺组织的高x线密度有关。在2例中，检测到阳性切除边缘(DCIS)，进一步切除可以避免重复手术干预。1例出现假阳性，但未对手术治疗结果产生负面影响。无假阴性结果。

Objective: Dental implant artifacts can compromise the quality of cone-beam computed tomography (CBCT) scans and challenge radiographic detection in surrounding regions. This literature review was conducted to examine the impact of implant angle modification on reducing metal artifacts in CBCT scans.

Materials and methods: A scoping review of literature was carried out in PubMed, Embase, Scopus, and Cochrane databases.

Results: Different spatial planes, including alpha, beta, gamma, and phi, along with 0°, 5.2°, 9.8°, 14.5°, 15°, 30°, 45°, 60°, 75°, and 90° angles were studied. Changes in the angular position of implants may reduce metal artifacts and improve the quality of CBCT scans.

Conclusions: Rotating implants within the alpha plane and angling them at 90° in the alpha plane enables reducing dental implant artifacts.

目的：种植体假影会影响锥形束计算机断层扫描（CBCT）的扫描质量，并对周围区域的放射检测构成挑战。本文献综述旨在探讨种植体角度改变对减少CBCT扫描中的金属伪影的影响。材料和方法：在PubMed， Embase， Scopus和Cochrane数据库中对文献进行了范围审查。结果：研究了0°、5.2°、9.8°、14.5°、15°、30°、45°、60°、75°和90°角度的α、β、γ和φ等不同空间平面。改变植入物的角度位置可以减少金属伪影，提高CBCT扫描质量。结论：在α平面内旋转种植体并在α平面内倾斜90°可减少种植体假影。

The article deals with the ultrasound diagnostics of the post radiation lung damage in 44 patients aged 32–73 years who received radiation therapy in the form of distance radiation therapy (DRT) for breast cancer. In all patients total focal dose (TFD) of radiation was 50 Gy with classical fractionation. The main types of subpleural post radiation injury, their intensity and prevalence were determined. The ultrasound findings were compared with CT images of patients six months after the start of DRT.

Maxillofacial dysostoses are congenital malformations of organs of head and neck, developing from the I and II gill arches. It is important to carry out differential diagnostics based on a comprehensive basic and additional examination aimed at determining all intracranial and extracranial symptoms specific for concrete syndrome, which is possible with modern methods of radiological diagnostic — CBCT and MSCT. The purpose of the study is to determine key aspects of choosing the computed tomography technique for diagnostics of maxillofacial dysostoses. From 2009 to 2023 215 MSCT and 86 CBCT were performed in 211 patients aged from 2 to 18 years old with maxillofacial dysostoses for the purpose of differential diagnostics of pathology, indications for choosing the volume of radiological examination were determined.

Objectives: Acute pulmonary embolism is a protentional fatal complication of COVID-19. The aim of this study is to investigate whether pulmonary embolism is due to thrombus migration from the venous circulation to the pulmonary arteries or due to local thrombus formation secondary to local inflammation. This was determined by looking at the distribution of pulmonary embolism in relation to lung parenchymal changes in patients with COVID-19 pneumonia.

Methods: Retrospectively, we identified pulmonary computed tomography angiography (CTPA) of patients admitted to the Royal Hospital between November 1st, 2020, and October 31, 2021, with a confirmed diagnosis of COVID-19. The CTPAs were examined for the presence of pulmonary embolism and the distribution of the pulmonary embolism in relation with lung parenchymal changes.

Results: A total of 215 patients admitted with COVID-19 pneumonia had CTPA. Out of them, 64 patients had pulmonary embolisms (45 men and 19 women; mean age: 58.4 years with a range of 36-98 years). The prevalence of pulmonary embolism (PE) was 29.8% (64/215). Pulmonary embolism was more frequently seen in the lower lobes. 51 patients had PE within the diseased lung parenchyma and 13 patients had PE within normal lung parenchyma.

Conclusion: The strong association between pulmonary artery embolism and lung parenchymal changes in patients admitted with COVID-19 pneumonia suggests local thrombus formation.

目的：急性肺栓塞是 COVID-19 的一种潜在致命并发症。本研究旨在探讨肺栓塞是由于血栓从静脉循环移至肺动脉，还是由于局部炎症继发的局部血栓形成。我们通过观察 COVID-19 肺炎患者肺栓塞的分布与肺实质变化的关系来确定这一点：我们回顾性地确定了皇家医院在 2020 年 11 月 1 日至 2021 年 10 月 31 日期间收治的确诊为 COVID-19 的患者的肺部计算机断层扫描血管造影（CTPA）。CTPA检查是否存在肺栓塞以及肺栓塞的分布与肺实质变化的关系：共有 215 名 COVID-19 肺炎患者接受了 CTPA 检查。其中，64 名患者患有肺栓塞（男性 45 人，女性 19 人；平均年龄 58.4 岁，介于 36-98 岁之间）。肺栓塞（PE）的发病率为 29.8%（64/215）。肺栓塞多发于肺下叶。51名患者的肺栓塞发生在病变的肺实质内，13名患者的肺栓塞发生在正常的肺实质内：结论：COVID-19 肺炎患者的肺动脉栓塞与肺实质变化密切相关，这表明局部血栓形成。

The study is devoted to determining the effect of the level of glycemic status, on the X-ray picture in patients with type 2 diabetes mellitus. The X-ray archive of 82 patients with pulmonary tuberculosis and type 2 diabetes mellitus was analyzed. The evaluation of the radiological picture was carried out with the correlation of the level of glucose in the blood. In patients with fasting glucose values of 10 mmol/l and above, the X-ray picture of tuberculosis was characterized by extensive areas of lung tissue consolidation, with a 50 % frequency of localization in the lower sections, with the rapid formation of decay cavities. The course of tuberculosis with severe tuberculous intoxication was observed in patients with sharp jumps in the daily blood glucose index of more than 5 mmol/l, even in patients with an average glucose index of no more than 8 mmol/l. The X-ray picture was characterized by the presence of areas of consolidation in the lungs on both sides with many air cavities and dropout foci; the appearance of new areas of consolidation against the background of anti-tuberculosis therapy.

The difficulties of timely diagnosis of primary multiple synchronous breast cancer with histological heterogeneity of tumors are demonstrated by a clinical example. Taking into account the fact that breast cancer continues to lead among all oncological pathology and accounts for 11.8% of all malignant neoplasms, diagnostic algorithms of the stage should be personalized. The presented clinical case demonstrates multidisciplinary errors committed at different stages of the patient’s examination.
