Abstract

Background:  Perivascular spaces (synonym: Virchow-Robin spaces) were first described over 150 years ago. They are defined as the fluid-filled spaces surrounding the small penetrating cerebral vessels. They gained growing scientific interest especially with the postulation of the so-called glymphatic system and their possible role in neurodegenerative and neuroinflammatory diseases.

Methods:  PubMed was used for a systematic search with a focus on literature regarding MRI imaging and evaluation methods of perivascular spaces. Studies on human in-vivo imaging were included with a focus on studies involving healthy populations. No time frame was set. The nomenclature in the literature is very heterogeneous with terms like "large", "dilated", "enlarged" perivascular spaces whereas borders and definitions often remain unclear. This work generally talks about perivascular spaces.

Results:  This review article discusses the morphologic MRI characteristics in different sequences. With the continual improvement of image quality, more and tinier structures can be depicted in detail. Visual analysis and semi or fully automated segmentation methods are briefly discussed.

Conclusion:  If they are looked for, perivascular spaces are apparent in basically every cranial MRI examination. Their physiologic or pathologic value is still under debate.

Key points:   · Perivascular spaces can be seen in basically every cranial MRI examination.. · Primarily T2-weighend sequences are used for visual analysis. Additional sequences are helpful for distinction from their differential diagnoses.. · There are promising approaches for the semi or fully automated segmentation of perivascular spaces with the possibility to collect more quantitative parameters..

血管周围间隙及其位置--磁共振成像和评估方法。
背景:血管周围间隙(同义词:Virchow-Robin 间隙)在 150 多年前首次被描述。它们被定义为穿透性小脑血管周围充满液体的空间。随着所谓的 "glymphatic 系统 "的提出以及它们在神经退行性疾病和神经炎症性疾病中可能扮演的角色,它们越来越受到科学界的关注:方法:使用 PubMed 进行系统检索,重点是有关磁共振成像和血管周围间隙评估方法的文献。其中包括有关人体活体成像的研究,重点是涉及健康人群的研究。未设定时间范围。文献中的术语非常不统一,如 "大的"、"扩张的"、"增大的 "血管周围间隙,而边界和定义往往不清楚。本文一般讨论的是血管周围间隙:这篇综述文章讨论了不同序列的 MRI 形态特征。随着图像质量的不断提高,越来越多的微小结构可以被详细描述。本文简要讨论了视觉分析和半自动或全自动分割方法:如果仔细观察,血管周围间隙基本上在每次头颅 MRI 检查中都很明显。其生理或病理价值仍存在争议:- 血管周围间隙基本上在所有头颅 MRI 检查中都能看到。- 主要采用T2-weighend序列进行直观分析。其他序列有助于与鉴别诊断进行区分。- 目前有一些很有前景的方法可用于血管周围空间的半自动或全自动分割,并有可能收集更多的定量参数......:- Seehafer S, Larsen N, Aludin S et al.血管周围空间和在哪里找到它们--核磁共振成像和评估方法》。Fortschr Röntgenstr 2024; DOI: 10.1055/a-2254-5651.

期刊介绍: Die RöFo veröffentlicht Originalarbeiten, Übersichtsartikel und Fallberichte aus dem Bereich der Radiologie und den weiteren bildgebenden Verfahren in der Medizin. Es dürfen nur Arbeiten eingereicht werden, die noch nicht veröffentlicht sind und die auch nicht gleichzeitig einer anderen Zeitschrift zur Veröffentlichung angeboten wurden. Alle eingereichten Beiträge unterliegen einer sorgfältigen fachlichen Begutachtung. Gegründet 1896 – nur knapp 1 Jahr nach der Entdeckung der Röntgenstrahlen durch C.W. Röntgen – blickt die RöFo auf über 100 Jahre Erfahrung als wichtigstes Publikationsmedium in der deutschsprachigen Radiologie zurück. Sie ist damit die älteste radiologische Fachzeitschrift und schafft es erfolgreich, lange Kontinuität mit dem Anspruch an wissenschaftliches Publizieren auf internationalem Niveau zu verbinden. Durch ihren zentralen Platz im Verlagsprogramm stellte die RöFo die Basis für das heute umfassende und erfolgreiche Radiologie-Medienangebot im Georg Thieme Verlag. Besonders eng verbunden ist die RöFo mit der Geschichte der Röntgengesellschaften in Deutschland und Österreich. Sie ist offizielles Organ von DRG und ÖRG und die Mitglieder der Fachgesellschaften erhalten die Zeitschrift im Rahmen ihrer Mitgliedschaft. Mit ihrem wissenschaftlichen Kernteil und dem eigenen Mitteilungsteil der Fachgesellschaften bietet die RöFo Monat für Monat ein Forum für den Austausch von Inhalten und Botschaften der radiologischen Community im deutschsprachigen Raum.
