When Emphysema Meets Fibrosis: A Pictorial Essay. 当肺气肿遇上纤维化:图文并茂的论文。
IF 3.3 4区 医学 Q1 Medicine Pub Date : 2024-01-01 Epub Date: 2023-07-10 DOI: 10.1097/RTI.0000000000000726

Many lung diseases, first, tumors, are smoking-related, and it is very likely to find more than one pattern in the same patient. Airspace enlargement with fibrosis (AEF) is one of them, but it has not been deeply understood or studied yet. In fact, we think that it might still be wrongly assimilated with other conditions that have different radiological features altogether and different prognoses. This pictorial essay is aimed at pointing out AEF so that radiologists and pulmonologists get acquainted with it and use the proper terminology, as AEF might not be that rare.

许多肺部疾病(首先是肿瘤)都与吸烟有关,而且很可能在同一个病人身上发现不止一种模式。气室扩大伴纤维化(AEF)就是其中之一,但人们对它的了解和研究还不够深入。事实上,我们认为它可能仍然被错误地与其他具有不同放射学特征和不同预后的疾病等同起来。这篇图文并茂的文章旨在指出 AEF,以便放射科医生和肺科医生了解它,并使用正确的术语,因为 AEF 可能并不那么罕见。

In the modern era of cardiac imaging, there is increasing use of cardiac computed tomography and cardiac magnetic resonance for visualization of congenital heart disease (CHD). Advanced visualization techniques such as virtual dissection, 3-dimensional modeling, and 4-dimensional flow are also commonly used in clinical practice. This review highlights such methods in five common forms of CHD, including double outlet right ventricle, common arterial trunk, sinus venosus defects, Tetralogy of Fallot variants, and heterotaxy, providing visualizations of pathology in both conventional and novel formats.

在现代心脏成像技术中,越来越多地使用心脏计算机断层扫描和心脏磁共振来观察先天性心脏病(CHD)。虚拟解剖、三维建模和四维血流等先进的可视化技术也常用于临床实践。本综述重点介绍了五种常见先天性心脏病的可视化方法,包括双出口右心室、共动脉干、窦静脉缺损、法洛氏四联症变异型和异位,以传统和新颖的形式提供病理可视化。

Neonatal and Infant Lung Disorders: Glossary, Practical Approach, and Diagnoses. 新生儿和婴儿肺部疾病:术语表,实用方法和诊断。
IF 3.3 4区 医学 Q1 Medicine Pub Date : 2024-01-01 Epub Date: 2023-11-03 DOI: 10.1097/RTI.0000000000000758

A multitude of lung disorders ranging from congenital and genetic anomalies to iatrogenic complications can affect the neonate or the infant within the first year of life. Neonatal and infant chest imaging, predominantly by plain radiography and computed tomography, is frequently employed to aid in diagnosis and management; however, these disorders can be challenging to differentiate due to their broad-ranging, and frequently overlapping radiographic features. A systematic and practical approach to imaging interpretation which includes recognition of radiologic patterns, utilization of commonly accepted nomenclature and classification, as well as interpretation of imaging findings in conjunction with clinical history can not only assist radiologists to suggest the diagnosis, but also aid clinicians in management planning. The contents of this article were endorsed by the leadership of both the World Federation of Pediatric Imaging (WFPI), and the International Society of Pediatric Thoracic Imaging (ISPTI).

许多肺部疾病,从先天性和遗传异常到医源性并发症,都可能在出生后的第一年影响新生儿或婴儿。新生儿和婴儿胸部成像,主要是通过x线平片和计算机断层扫描,经常用于帮助诊断和管理;然而,由于这些疾病范围广泛,并且经常重叠的影像学特征,因此很难区分。一种系统实用的影像学解释方法,包括对放射学模式的识别,普遍接受的命名法和分类的使用,以及结合临床病史对影像学结果的解释,不仅可以帮助放射科医生提出诊断建议,还可以帮助临床医生制定管理计划。本文的内容得到了世界儿科影像联合会(WFPI)和国际儿科胸部影像学会(ISPTI)领导的认可。

Magnetic Resonance Imaging of Pediatric Lungs and Airways: New Paradigm for Practical Daily Clinical Use. 小儿肺和气道的磁共振成像:实用日常临床应用的新范例。
IF 3.3 4区 医学 Q1 Medicine Pub Date : 2024-01-01 Epub Date: 2023-03-31 DOI: 10.1097/RTI.0000000000000707

Disorders of the lungs and airways are among the most common indications for diagnostic imaging in infants and children. Traditionally, chest radiograph has been the first-line imaging test for detecting these disorders and when cross-sectional imaging is necessary, computed tomography (CT) has typically been the next step. However, due to concerns about the potentially harmful effects of ionizing radiation, pediatric imaging in general has begun to shift away from CT toward magnetic resonance imaging (MRI) as a preferred modality. Several unique technical challenges of chest MRI, including motion artifact from respiratory and cardiac motion as well as low signal-to-noise ratios secondary to relatively low proton density in the lung have slowed this shift in thoracic imaging. However, technical advances in MRI in recent years, including developments in non-Cartesian MRI data sampling methods such as radial, spiral, and PROPELLER imaging and the development of ultrashort TE and zero TE sequences that render CT-like high-quality imaging with minimal motion artifact have allowed for a shift to MRI for evaluation of lung and large airways in centers with specialized expertise. This article presents a practical approach for radiologists in current practice to begin to consider MRI for evaluation of the pediatric lung and large airways and begin to implement it in their practices. The current role for MRI in the evaluation of disorders of the pediatric lung and large airways is reviewed, and example cases are presented. Challenges for MRI of the lung and large airways in children are discussed, practical tips for patient preparation including sedation are described, and imaging techniques suitable for current clinical practice are presented.

肺部和气道疾病是婴幼儿诊断成像最常见的适应症之一。传统上,胸片是检测这些疾病的一线成像检查方法,当需要进行横断面成像时,计算机断层扫描(CT)通常是下一步检查方法。然而,由于担心电离辐射的潜在危害,儿科成像已开始从 CT 转向磁共振成像 (MRI) 作为首选方式。胸部核磁共振成像存在一些独特的技术难题,包括呼吸和心脏运动造成的运动伪影,以及肺部质子密度相对较低导致的低信噪比,这些都减缓了胸部成像的转变。然而,近年来磁共振成像技术的进步,包括非笛卡尔磁共振成像数据取样方法(如径向、螺旋和 PROPELLER 成像)的发展,以及超短 TE 和零 TE 序列的开发,这些技术可提供类似 CT 的高质量成像,同时将运动伪影降到最低。本文介绍了一种实用的方法,让放射科医生在目前的实践中开始考虑用磁共振成像评估小儿肺部和大气管,并开始在他们的实践中实施。文章回顾了磁共振成像目前在评估小儿肺部和大气管疾病中的作用,并列举了一些病例。讨论了儿童肺部和大气道核磁共振成像所面临的挑战,介绍了包括镇静在内的患者准备实用技巧,并介绍了适合当前临床实践的成像技术。

Purpose: The primary imaging modality for the diagnosis of mitral valve prolapse (MVP) is echocardiography supplemented by electrocardiography (ECG)-gated cardiac computed tomography (CT) angiography. However, we have recently encountered patients with MVP who were initially identified on non-ECG-gated enhanced chest CT. The purpose of this study is to evaluate the diagnostic accuracy of non-ECG-gated enhanced chest CT to predict the presence of MVP.

Patients and methods: Of 92 patients (surgically confirmed MVP who underwent non-ECG-gated chest CT), 27 patients were excluded for motion artifact or insufficient surgical correlation, and 65 patients were ultimately included. As a control, 65 patients with dyspnea and without MVP (non-ECG-gated chest CT and echocardiography were performed within 1 month) were randomly selected. We retrospectively analyzed an asymmetric double line sign on axial CT images for the presence of MVP. The asymmetric double line sign was defined as the presence of a linear structure, not located in the plane traversing the mitral annulus.

Results: Use of the asymmetric double line sign to predict MVP on non-ECG-gated CT showed modest sensitivity, high specificity, modest negative predictive value, and high positive predictive value of 59% (38/65), 99% (64/65), 70% (64/91), and 97% (38/39), respectively.

Conclusion: The asymmetric double line sign on non-ECG-gated enhanced chest CT may be a valuable finding to predict the presence of MVP. Familiarity with this CT finding may lead to prompt diagnosis and proper management of MVP.

目的:诊断二尖瓣脱垂(MVP)的主要成像方式是超声心动图辅助心电图(ECG)门控心脏计算机断层扫描(CT)血管造影。然而,我们最近遇到的MVP患者最初是在非ecg门控增强胸部CT上发现的。本研究的目的是评估非ecg门控增强胸部CT诊断MVP存在的准确性。患者和方法:92例患者(手术证实MVP,行非心电图门控胸部CT)中,27例患者因运动伪影或手术相关性不足被排除,最终纳入65例患者。作为对照,随机选择呼吸困难且无MVP的患者65例(1个月内进行非心电图门控胸部CT和超声心动图检查)。我们回顾性分析了轴向CT图像上的不对称双线征,以确定MVP的存在。不对称双线标志被定义为存在线性结构,不位于穿过二尖瓣环的平面上。结果:应用非ecg门控CT非对称双线征象预测MVP,灵敏度适中,特异性高,阴性预测值适中,阳性预测值较高,分别为59%(38/65)、99%(64/65)、70%(64/91)和97%(38/39)。结论:非ecg门控增强胸部CT上的不对称双线征可能是预测MVP存在的一个有价值的发现。熟悉这一CT表现有助于及时诊断和正确处理MVP。
