To compare intra-individual percentage diameter stenosis (PDS) measurements of coronary artery stenoses between energy-integrating detector computed tomography (EID-CT) and a clinical photon-counting detector computed tomography (PCD-CT) systems using similar acquisition and reconstruction settings.Patients (n = 23, mean age of 65 ± 12.1 years, out of these 16 (69.6%) male) were imaged on a conventional EID- and a clinical PCD-CT system with a median of 5.5 (3.0–12.5) days apart. Sequential CCTA scans were acquired and reconstructed using similar settings, including a vascular Bv36 kernel, a tube voltage of 110 kVp for EID-CT vs 120 kVp for PCD-CT, a slice thickness of 0.5 for EID-CT vs 0.6 for PCD-CT, and an iterative reconstruction strength of 3 on EID-CT vs a virtual monoenergetic reconstruction at 55 keV and quantum iterative reconstruction level of 3 on PCD-CT. Radiation dose, contrast volume, and injection parameters were matched as similarly as possible between the systems. PDS measurements were performed according to the coronary artery disease reporting and data system (CAD-RADS) by two trained readers and compared between the different modalities using the Wilcoxon rank sum test, Spearman correlation, and Bland-Altman analysis.PCD-CT measured significantly lower PDS values than EID-CT [PDSEID-CT: 45.1% (35.1%–64.0%) vs. PDSPCD-CT 44.2% (32.4%–61.0%), P < 0.0001]. This difference led to a mean bias of 1.8 (LoA −3.0/6.5) with an excellent ICC (0.99) value among EID- and PCD-CT. The mean intra-individual deviation between the examinations was 1.8% between the scanners. This led to CAD-RADS re-classification in 3/23 cases (13.0%, new-lower class) for the first reader, and in 4/23 cases (13.0%, new-lower and 4.4%, new-higher class) for the second reader. Inter-reader agreement between the two readers for each stenosis was very strong (ICC = 0.98).Coronary artery stenosis measurements from PCD-CT correlate strongly to EID-CT-based measurements, despite the tendency of the measurement from PCD-CT being lower. This difference led to a change in CAD-RADS classification in 17.4% of patients. The effects on clinical decision-making, downstream testing, and prognosis have to be evaluated in future studies.
比较使用类似采集和重建设置的能量积分探测器计算机断层扫描(EID-CT)和临床光子计数探测器计算机断层摄影(PCD-CT)系统之间冠状动脉狭窄的个体内直径百分比狭窄(PDS)测量值。患者(n=23,平均年龄65±12.1岁,其中16名(69.6%)男性)在常规EID和临床PCD-CT系统上进行成像,中间间隔5.5(3.0-12.5)天。使用类似的设置采集和重建连续CCTA扫描,包括血管Bv36内核,110的管电压 EID-CT与120的kVp PCD-CT的kVp,EID-CT的切片厚度为0.5,PCD-CT为0.6,EID-CT的迭代重建强度为3,虚拟单能重建为55 keV和PCD-CT上3的量子迭代重建水平。辐射剂量、造影剂体积和注射参数在系统之间尽可能相似地匹配。PDS测量由两名受过训练的读者根据冠状动脉疾病报告和数据系统(CAD-RADS)进行,并使用Wilcoxon秩和检验、Spearman相关性和Bland-Altman分析在不同模式之间进行比较。PCD-CT测得的PDS值明显低于EID-CT【PDSEID-CT:45.1%(35.1%-64.0%)vs.PDSSPCD-CT 44.2%(32.4%-61.0%),P<0.0001】。这一差异导致平均偏差为1.8(LoA−3.0/6.5),EID-和PCD-CT之间的ICC值为0.99。扫描仪之间检查的平均个体内偏差为1.8%。这导致第一位读者在3/23例(13.0%,新的低级别)中对CAD-RADS进行了重新分类,第二位读者在4/23例(130%,新低级别和4.4%,新高级别)中进行了CAD-RADS重新分类。两位读者之间对每种狭窄的一致性非常强(ICC=0.98)。尽管PCD-CT的测量值有降低的趋势,但PCD-CT测量的冠状动脉狭窄与基于EID CT的测量值密切相关。这种差异导致17.4%的患者的CAD-RADS分类发生变化。对临床决策、下游检测和预后的影响必须在未来的研究中进行评估。

Herpes zoster ophthalmicus is a viral infection caused by the varicella-zoster virus, affecting the ophthalmic branch of the trigeminal nerve, called the ophthalmic nerve. Herpes zoster ophthalmicus is characterized by a painful rash and blisters on one side of the forehead and around the eye, along with symptoms such as eye redness, tearing, and sensitivity to light, and can also lead to serious complications, such as corneal ulcers, glaucoma, and vision loss, particularly if the eye is involved. Herpes zoster myositis and oculomotor nerve involvement are rare complications of herpes zoster infection. Early diagnosis and treatment, such as antiviral medications, corticosteroids, and pain management, are important to prevent complications and to alleviate symptoms. In our case report we demonstrate the case of an 81-year-old female patient with left sided herpes zoster ophthalmicus, associated with MRI proved orbital myositis and oculomotor nerve involvement. Symptoms were slowly reduced with antiviral therapy. People who develop symptoms of herpes zoster ophthalmicus should seek prompt medical attention to receive appropriate care and to avoid serious complications.
眼带状疱疹是一种由水痘带状疱疹病毒引起的病毒感染,影响三叉神经的眼支,称为眼神经。眼部带状疱疹的特点是额头一侧和眼睛周围出现疼痛的皮疹和水泡,并伴有眼睛发红、流泪和对光敏感等症状,还可能导致严重的并发症,如角膜溃疡、青光眼和视力丧失,特别是当眼睛受累时。带状疱疹肌炎和动眼神经受累是带状疱疹感染的罕见并发症。早期诊断和治疗,如抗病毒药物、皮质类固醇和疼痛管理,对预防并发症和减轻症状很重要。在我们的病例报告中,我们展示了一例81岁的女性左侧带状疱疹患者,MRI证实眼眶肌炎和动眼神经受累。抗病毒治疗后症状缓慢减轻。出现眼部带状疱疹症状的人应立即就医,接受适当的治疗,避免严重的并发症。

Parathyroid scintigraphy is an imaging technique that uses gamma-emitting radionuclide to locate hyperfunctioning parathyroid glands in patients with hyperparathyroidism. It is valuable for preoperative assessment before parathyroidectomy, which is a curative surgery in most cases of primary hyperparathyroidism and some cases of secondary hyperparathyroidism. There are several different techniques for parathyroid scintigraphy. In general, the scintigraphy is performed with Tc-99m MIBI, a mitochondria-targeting radiotracer. Some techniques also supply the Tc-99m MIBI scintigraphy with thyroid scintigraphy to differentiate between thyroid and parathyroid tissue. Parathyroid scintigraphy can detect primary hyperparathyroidism with a sensitivity of 80% and a specificity of 84%. It can also detect secondary hyperparathyroidism with a sensitivity of 58% and a specificity of 93%. The unique advantage of parathyroid scintigraphy is the ability to identify supernumerary and ectopic parathyroid abnormalities, which can significantly affect surgical planning and outcomes.
甲状旁腺闪烁扫描是一种使用伽马发射放射性核素定位甲状旁腺功能亢进患者甲状旁腺的成像技术。它对甲状旁腺切除术前的术前评估是有价值的,甲状旁腺切除术是大多数原发性甲状旁腺功能亢进症和一些继发性甲状旁腺功能减退症的治疗性手术。甲状旁腺闪烁扫描有几种不同的技术。一般来说,闪烁扫描是用Tc-99m MIBI(一种线粒体靶向放射性示踪剂)进行的。一些技术还提供Tc-99m MIBI闪烁扫描与甲状腺闪烁扫描,以区分甲状腺和甲状旁腺组织。甲状旁腺闪烁扫描可以检测原发性甲状旁腺功能亢进,灵敏度为80%,特异性为84%。它还可以检测继发性甲状旁腺功能亢进,灵敏度为58%,特异性为93%。甲状旁腺闪烁扫描的独特优势是能够识别多生和异位甲状旁腺异常,这会显著影响手术计划和结果。

Despite improvements in the imaging modalities, the optimal protocol for extracranial facial nerve imaging using 1.5 T MRI is still debatable. Pre-operative mapping of the facial nerve could provide valuable information for surgeons. The current study aimed to evaluate and choose proper 1.5 T MRI protocols for the extracranial segment of facial nerve pre-op imaging.Extracranial facial nerves on the tumoral and normal side of 19 patients (38 nerves) were imaged by 1.5 T MRI, using five sequences including T1-weighted, T2-weighted, T1-weighted-fat-saturated with contrast, Three-dimensional (3D) T1-weighted and 3D T2-weighted. The visibility of each of the three segments of the extracranial facial nerve (the main trunk, cervicofacial and temporofacial divisions and terminal branches) in each sequence was assessed.On the normal side, segments 1 and 2 of the nerve were identifiable in all patients and segment 3 was identifiable in 89.5% of patients in both 3D T1-weighted and 3D T2-weighted sequences. On the tumoral side, segments 1, 2 and 3 were identifiable in 89.5, 84.2 and 68.4% of patients, respectively, in 3D T1-weighted and T2-weighted sequences. 3D sequences showed significant improvement in visualizing extracranial facial nerve and its branches compared to routine T1-weighted and T2-weighted sequences.Our protocol showed favourable results in visualizing the extracranial facial nerve and its branches. We believe the protocol used in this study could be used as a pre-operative facial nerve mapping method using 1.5 T MRI.
尽管成像方式有所改进,但使用1.5 T MRI仍有争议。面神经的术前标测可以为外科医生提供有价值的信息。目前的研究旨在评估和选择合适的1.5 面神经颅外段术前成像的T MRI协议。用1.5 T MRI,使用五个序列,包括T1加权、T2加权、T1加权对比饱和脂肪、三维(3D)T1加权和3D T2加权。评估了每个序列中颅外面神经三段(主干、颈面部和颞面部分区以及终末支)的可见性。在正常侧,在3D T1加权和3D T2加权序列中,所有患者均可识别神经节段1和2,89.5%的患者可识别神经节3。在肿瘤侧,在3D T1加权和T2加权序列中,89.5%、84.2%和68.4%的患者可识别片段1、2和3。与常规T1加权和T2加权序列相比,3D序列在显示颅外面神经及其分支方面显示出显著改善。我们的方案在显示颅外面神经及其分支方面显示了良好的结果。我们相信本研究中使用的方案可以用作术前面部神经标测方法,使用1.5 T MRI。

Since the initial release of the World Wide Web, the capabilities of web browsers have grown from presenting formatted documents to running complex programs, such as 3D game engines. The medical imaging community started to adopt technologies that came with the fifth major version of the HyperText Markup Language (HTML5). It led to the creation of various web-based radiological applications such as cornerstone.js or BrainBrowser. BrainBrowser supports both 3D and 2D rendering of neuroimaging data. However, it cannot run important image processing algorithms, such as brain extraction and linear registration, which are essential in most neuroimaging workflows. The most commonly used library that supports these algorithms is the FMRIB Software Library (FSL). We aim to build a web-based cross-platform neuroimaging platform that combines data visualization with image processing.We built our system as an extension of BrainBrowser. We developed WebMRI in JavaScript and designed the user interface using HTML, CSS, and Bootstrap. We used Emscripten to port the brain extraction and linear registration tools of FSL to the web.We built WebMRI, a fully web-based extensible neuroimaging platform that combines the visualization capabilities of BrainBrowser with the brain extraction and linear registration tools of FSL by porting them from C++ to WebAssembly. We extended BrainBrowser with a plugin system that makes it easy to bring other processing algorithms into the platform. We released the WebMRI source code on Github: https://github.com/wpmed92/WebMRI.We developed and released WebMRI, a web-based cross-platform open-source neuroimaging platform.
自万维网首次发布以来,网络浏览器的功能已经从呈现格式化文档发展到运行复杂程序,如3D游戏引擎。医学成像社区开始采用超文本标记语言(HTML5)第五个主要版本附带的技术。它导致了各种基于网络的放射学应用程序的创建,如cornerstone.js或BrainBrowser。BrainBrowser支持神经成像数据的3D和2D渲染。然而,它无法运行重要的图像处理算法,如大脑提取和线性配准,这在大多数神经成像工作流程中是必不可少的。支持这些算法的最常用的库是FMRIB软件库(FSL)。我们的目标是建立一个基于网络的跨平台神经成像平台,将数据可视化与图像处理相结合。我们将系统构建为BrainBrowser的扩展。我们用JavaScript开发了WebMRI,并使用HTML、CSS和Bootstrap设计了用户界面。我们使用Emscripten将FSL的大脑提取和线性配准工具移植到网络上。我们构建了WebMRI,这是一个完全基于网络的可扩展神经成像平台,通过将BrainBrowser的可视化功能与FSL的大脑提取和线性配准工具从C++移植到WebAssembly,将其结合在一起。我们用一个插件系统扩展了BrainBrowser,使其可以轻松地将其他处理算法引入平台。我们在Github上发布了WebMRI源代码:https://github.com/wpmed92/WebMRI.We开发并发布了WebMRI,这是一个基于网络的跨平台开源神经成像平台。
