Gastric ischemia: cross-sectional imaging findings via a case series.

Gastric ischemia is an uncommon, serious, and potentially fatal disease caused by diffuse or focal gastric vascular insufficiency. It can be caused by states of systemic hypotension or disseminated vasculitis or thrombosis, even though the stomach possesses collateral circulation that prevents it from developing to a certain extent. Computed tomography (CT) is the technique of choice to assess the extent of the disease, as it detects parietal hypoenhancement and gastric and/or portal pneumatosis. The treatment required depends on the etiology and ranges from surgery to resuscitation measures. This article presents the imaging findings from a series of three cases of gastric ischemia seen at our hospital.

Instagram's Influence on Radiology Today: Reviewing the Evolving Educational Journey from a Hospital to National Societies.

We define social media as an interactive online platform that allows users to communicate and exchange knowledge. Educational and medical profiles have slowly emerged on different social media platforms, helping to teach about and publicize diverse aspects of medicine. Radiology is one of the specialties that could potentially benefit the most from social media, as the radiologist tends to have little outside-the-hospital representation. Progressively, audiovisual content has been gaining ground on social networks: Facebook, Twitter, Instagram, Youtube, TikTok, etc. Instagram appears to be ideally suited for radiology given its image-based nature. In addition, Instagram can also be used as a tool to help radiologists share and discuss radiological images, improve communication with clinicians and patients, advertise themselves and their specialty, and humanize their profession. Nevertheless, legal matters and privacy issues should always be taken into account when using these tools. In this overview, we describe the development of social networks and communication tools in our own radiology department, focusing especially on our Instagram account, as it has had a wide impact on our hospital and radiology residents around the country. We will also provide a summary of the various social media platforms used for radiology education along with their pros and cons, including useful tips for safe and efficient use.

Zinner syndrome: a radiological journey through a little known condition.

Zinner syndrome is a rare congenital urological entity, secondary to an alteration in embryogenesis between 4th and 13th weeks of gestation, specifically because of abnormalities in the development of the distal mesonephric duct. It is characterized by the triad of unilateral renal agenesis, cystic dilatation of the ipsilateral seminal vesicle and ipsilateral ejaculatory duct obstruction. The aim of this article is to provide the reader with all the necessary information to be able to suspect the presence of this syndrome, reviewing its physiopathology, clinical manifestations and the imaging techniques that enable its diagnosis, emphasizing those radiological findings by MRI that should lead us to think about it. This work is illustrated with representative radiological images of cases belonging to our institution, including patients with different variants of Zinner syndrome. We also include an overview of the embryology of the male urogenital system, to remember the role of the mesonephric duct and the ureteral bud in the formation of the different urogenital structures, as well as a differential diagnosis that allows us to differentiate seminal vesicle cysts from other pelvic cystic lesions.

High perilesional T2-FLAIR signal around anterior temporal perivascular spaces: How can fluid suppressed Amide Proton Transfer weighted imaging further comfort the diagnosis.

Areas of marked T2-FLAIR hyperintensity around perivascular spaces can be misdiagnosed as tumor, especially in case of lesion evolution. In this report, we show and describe increased T2-FLAIR signal intensity around anterior temporal perivascular spaces in three patients and shortly review this poorly known entity. In addition, we discuss for the first time the added value of fluid suppressed APTw imaging, an emerging noninvasive molecular technique, in the characterization of this "do not touch" abnormality.
