Primary bone tumours of the jaw are rare tumoral entities and do substantially differ from other bone tumours of the human body with respect of their frequently encountered unusual radiological appearances. The reason for that may be confined to the co-existence of two closely neighbored but different anatomical structures (i.e., tooth-forming apparatus and jaw bones with adjacent gingiva) and some tumour pathologies which are nearly excusively encountered in the jaw bones only (e.g., ameloblastoma, ossifying fibroma, ghost cell carcinoma).This paper would like to highlight some basic principles of the diagnostic approach and possibilities of radiological differentiation of such tumour-suspicious changes within the gnathic system are elucidated and discussed.The paper presented here is substantially based on the most recent classification of odontogenic and maxillofacial tumours (5th edition, 2022) which serves as a scaffold for the selection of typical tumour entities. Due to the educational character of this paper, only important jaw tumours worth mentioning and their characteristics are subject to be extracted from the literature and further discussed.The main focus was put onto both the description of radiological tumoral appearance and the rational selection of a radiological diagnostic work-up. In order to better visualize this difficult field of tumour entities, much attention has been paid on a comprehensive pictorial essay.For radiologists, it is their foremast task to detect, describe, and to classify bone tumours of the jaw when they are found intentionally or accidentally, resp. A close co-operation with their clinical partners is of upmost importance to gain information about patient´s history and clinical presentation. It is readily reasonable that radiologists are mostly able to provide only a suggestion of the presented tumour entity but this expert opinion would be very helpful to further narrow down the list of potential differential diagnoses (e.g., differentiation of a cyst vs. solid tumour osteolysis, identification of jaw osteomyelitis vs. tumoral infiltration, recognizing of secondary tumour involvement of the jaw). · primary bone tumours of the jaw are very rare, moreover difficult to differentiate radiologically, and do need therefore histological proof;. · profound knowledge about tumour characteristics (location within the jaw, relationship to the tooth, bony destructive pattern) may allow a rough orientation and classification;. · matrix-forming tumours and dysplasias of the jaw facilitates their radiological differentiation and classification;. · in contrary, osteolyses should be thoroughly scrutinized for the more frequent gnathic cysts in differentiation of rather rare solid primary tumours;. · an interdisciplinary round-table discussion amongst well-experienced maxillofacial surgeons and specialized radiologists may be appropriate to avoid severe misinterpretations.. · Grieser T, Hirsch E, Tödtmann

颌骨原发性骨肿瘤是一种罕见的肿瘤实体，与人体其他骨肿瘤在放射学表现上有很大不同。究其原因，可能仅限于两种紧密相邻但又不同的解剖结构（即牙齿形成装置和颌骨以及相邻的牙龈）同时存在，以及一些几乎只在颌骨中才会出现的肿瘤病理（如：釉母细胞瘤、骨化性纤维瘤、鬼臼瘤）、本文希望强调诊断方法的一些基本原则，并阐明和讨论在颌骨系统内对此类肿瘤可疑病变进行放射学鉴别的可能性。本文主要基于最新的牙源性和颌面部肿瘤分类（第 5 版，2022 年），该分类可作为选择典型肿瘤实体的支架。由于本文的教育性质，只有值得一提的重要颌骨肿瘤及其特征才会从文献中摘录并进一步讨论。本文的重点是肿瘤放射学外观的描述和放射学诊断工作的合理选择。放射科医生的首要任务是在有意或无意发现颌骨肿瘤时对其进行检测、描述和分类，而与临床伙伴的密切合作对于获取患者病史和临床表现的信息至关重要。放射科医生大多只能提供肿瘤实体的建议，这一点很容易理解，但专家的意见将非常有助于进一步缩小潜在鉴别诊断的范围（例如，区分囊肿与实体瘤溶骨，鉴别颌骨骨髓炎与肿瘤浸润，识别颌骨的继发性肿瘤受累）。- 颌骨的原发性骨肿瘤非常罕见，而且很难通过放射学方法进行鉴别，因此需要组织学证明；...- 对肿瘤特征（在颌骨内的位置、与牙齿的关系、骨质破坏模式）的深入了解可以帮助进行粗略的定位和分类；以及- 颌骨基质形成性肿瘤和发育不良有助于它们的放射学区分和分类；。- 相反，在对罕见的实性原发肿瘤进行鉴别时，应仔细检查骨溶解物中更常见的龈囊肿；以及- 由经验丰富的颌面外科医生和专业放射科医生进行跨学科圆桌讨论，可避免严重的误读。- Grieser T, Hirsch E, Tödtmann N.

Since the approval of the first dual-source photon-counting detector CT (PCD-CT) in the fall of 2021, significant insights have been gained in its application for cardiovascular imaging. This review aims to provide a comprehensive overview of the current state of knowledge and the growing body of research literature, illustrating innovative applications and perspectives through case examples.We conducted a structured literature review, identifying relevant studies via Google Scholar and PubMed, using the keywords "photon-counting detector", "cardiovascular CT", "cardiac CT", and "ultra-high-resolution CT". We analyzed studies published since January 2015. Additionally, we integrated our own clinical experiences and case examples.In addition to the well-known benefit of increased temporal resolution offered by dual-source scanners, dual-source PCD-CT provides three key advantages: 1) Optimized geometric dose efficiency with an improved contrast-to-noise ratio, 2) intrinsic spectral sensitivity, and 3) the ability for ultrahigh-resolution CT. This technology enables improved image quality or radiation dose reduction in established cardiovascular protocols. Its use in non-invasive cardiac diagnostics for obese patients, those with a high plaque burden, or after stent implantation appears technically feasible, potentially expanding the scope of CT. The spectral sensitivity also allows tailored image acquisition, reducing metallic artifacts and contrast agent doses in patients with renal impairment. Early studies and clinical experience support these potential applications of PCD-CT in cardiovascular diagnostics, suggesting workflow optimization and improved patient management.However, challenges remain, including high costs, large data volumes, somewhat longer reconstruction times, and technical difficulties in combining spectral sensitivity with ultra-high resolution. Prospective randomized studies with clinical endpoints are lacking to confirm the clear advantage over conventional scanners. Future research should focus on endpoint-based studies and robust cost-benefit analyses to evaluate the potential of this technology and facilitate its evidence-based integration in clinical practice. · Photon-counting detector CT represents a technological advancement in computed tomography.. · Spectral sensitivity enhances iodine signal and minimizes artifacts.. · Ultra-high-resolution CT allows precise imaging, even in stents and advanced sclerosis.. · This technology must be validated through endpoint-based, randomized studies.. · Hagar MT, Schlett CL, Oechsner T et al.

自 2021 年秋季首台双源光子计数探测器 CT（PCD-CT）获得批准以来，人们对其在心血管成像中的应用有了更深入的了解。本综述旨在全面概述当前的知识状况和不断增长的研究文献，并通过案例说明创新应用和观点。我们进行了结构化文献综述，通过谷歌学术和 PubMed，以 "光子计数探测器"、"心血管 CT"、"心脏 CT "和 "超高分辨率 CT "为关键词，确定了相关研究。我们分析了自 2015 年 1 月以来发表的研究。此外，我们还结合了自己的临床经验和病例。除了众所周知的双源扫描仪可提高时间分辨率这一优点外，双源 PCD-CT 还具有三大优势：1) 优化几何剂量效率，提高对比-噪声比；2) 固有光谱灵敏度；3) 能够进行超高分辨率 CT。该技术可在既定的心血管方案中提高图像质量或减少辐射剂量。将其用于肥胖患者、高斑块负荷患者或支架植入术后的无创心脏诊断在技术上似乎是可行的，有可能扩大 CT 的应用范围。它的光谱灵敏度还能进行定制图像采集，减少金属伪影，降低肾功能受损患者的造影剂剂量。早期研究和临床经验支持 PCD-CT 在心血管诊断中的这些潜在应用，表明工作流程得到优化，患者管理得到改善。然而，挑战依然存在，包括成本高、数据量大、重建时间稍长，以及将光谱灵敏度与超高分辨率相结合的技术难题。目前还缺乏临床终点的前瞻性随机研究来证实与传统扫描仪相比的明显优势。未来的研究应侧重于基于终点的研究和可靠的成本效益分析，以评估该技术的潜力并促进其在临床实践中的循证整合。- 光子计数探测器 CT 代表了计算机断层扫描的技术进步。- 光谱灵敏度增强了碘信号并最大限度地减少了伪影。- 超高分辨率 CT 可实现精确成像，即使是在支架和晚期硬化的情况下。- 这项技术必须通过基于终点的随机研究来验证。- Hagar MT、Schlett CL、Oechsner T 等人，《光子计数探测器 CT：心血管成像的进展与临床应用》。Fortschr Röntgenstr 2024; DOI 10.1055/a-2452-0288.

Chronic pelvic pain may cause a significant reduction in the quality of life for affected women, and the extent of the limitation is often underestimated. Chronic pain can lead to lifelong problems. Currently, PCS is probably significantly underdiagnosed as a cause of chronic pelvic pain in women. To diagnose PCS, other common causes of chronic pelvic pain must be excluded and typical changes in pelvic vein syndrome must be detected, ideally using MR phlebography. If the indication is correct and the procedure is carried out appropriately - ideally by experienced interventionalists certified according to DeGIR/EBIR - the symptoms can be eliminated in the long term with a high success rate and few complications. Simultaneous psychotherapeutic treatment should always be discussed with the patients. · PCS is a common cause of chronic pelvic pain in women.. · Imaging requires Doppler sonography and contrast-enhanced magnetic resonance angiography.. · Typical symptoms and dilated pelvic veins (>8 mm) indicate interventional therapy.. · Pathological pelvic veins are embolized using coils and alcohol foam.. · Published success rates and long-term results suggest propagating interventional therapy.. · Paulus T, Minko P, Petersen T et al.

慢性盆腔疼痛可能会大大降低受影响妇女的生活质量，而且其限制程度往往被低估。慢性疼痛可导致终身问题。目前，PCS 作为女性慢性盆腔疼痛的一个病因，可能被严重低估。要诊断 PCS，必须排除导致慢性盆腔疼痛的其他常见原因，并检测盆腔静脉综合征的典型变化，最好使用磁共振静脉造影术。如果适应症正确，手术实施得当，最好由经验丰富的、获得 DeGIR/EBIR 认证的介入专家进行，则可长期消除症状，且成功率高，并发症少。应始终与患者讨论同时进行的心理治疗。- PCS 是导致女性慢性盆腔疼痛的常见原因。- 影像学检查需要进行多普勒超声检查和造影剂增强磁共振血管造影检查。- 典型症状和盆腔静脉扩张（>8 毫米）提示介入治疗。- 使用线圈和酒精泡沫对病理性盆腔静脉进行栓塞。- 已公布的成功率和长期结果表明介入疗法具有推广价值。- Paulus T, Minko P, Petersen T 等人.女性盆腔静脉疾病--诊断与治疗.Fortschr Röntgen, 2009.Fortschr Röntgenstr 2024; DOI 10.1055/a-2446-0749.

Elbow pain can result in significant morbidity. MRI can help diagnosing the cause of elbow pain.Based on a systematic literature search as well as knowledge gained through frequent participation in conferences dedicated to advances in musculoskeletal imaging, this review aims to give a brief overview of normal anatomy and common pathologies of tendons and ligaments of the elbow on magnetic resonance imaging.Stabilization of the elbow joint is provided by osseous structures and passive ligamentous and active muscular support. Loss of these important stabilizers, due to trauma and overuse, can result in elbow instability. Additional MR views or intra-articular contrast media can be useful for the detection of specific pathologies.MRI is frequently used to detect posttraumatic or chronic conditions, which can lead to posterolateral or posteromedial elbow instability. Knowledge of normal anatomy, variants, pathologies, as well as appropriate imaging is crucial to make the diagnosis. · Epicondylitis occurs due to chronic degeneration with tendinosis and partial tendon tearing and is not related to an acute inflammatory reaction.. · Posterolateral or posteromedial elbow instability can be the result of trauma with loss of passive ligamentous and active muscular stabilization.. · The most common elbow instability is posterolateral rotatory instability with the LUCL being the most important stabilizer affected by injury.. · Schinnerl C, Weber M, Benninger E et al. MRI of the Elbow - Update 2024. Fortschr Röntgenstr 2024; DOI 10.1055/a-2416-1491.

肘部疼痛可导致严重的发病率。基于系统的文献检索以及经常参加肌肉骨骼成像进展会议所获得的知识，本综述旨在简要概述磁共振成像中肘部肌腱和韧带的正常解剖和常见病理。由于创伤和过度使用，这些重要稳定器的丧失会导致肘关节不稳定。核磁共振成像常用于检测创伤后或慢性疾病，这些疾病可导致肘关节后外侧或后内侧不稳。了解正常解剖结构、变异、病理以及适当的影像学检查对诊断至关重要。- 上髁炎是由于慢性退行性变引起的肌腱硬化和部分肌腱撕裂，与急性炎症反应无关。- 肘关节后外侧或后内侧不稳可能是由于外伤导致被动韧带和主动肌肉失去稳定。- 最常见的肘关节不稳定是后外侧旋转性不稳定，而LUCL是受伤后最重要的稳定器。- Schinnerl C, Weber M, Benninger E et al.Fortschr Röntgenstr 2024; DOI 10.1055/a-2416-1491.
