Social media for radiologists: opportunities and challenges.

The use of social media in medicine offers unprecedented opportunities for social interaction. Activity on platforms such as X (formerly Twitter), Instagram, Facebook, and LinkedIn plays crucial roles in various medical services, particularly regarding patients' access to information and healthcare services, medical education, and professional networking. However, the integration of social media into healthcare is not challenge-free and has certain pitfalls. In this article, we address several critical issues that compromise the reliability and effectiveness of social media as a professional healthcare resource, particularly in the field of radiology. We discuss possible solutions and tips and tricks to facilitate the use of this valuable tool to our advantage and in a reliable manner.

Beyond the revised atlanta classification: a comprehensive review of the imaging assessment of acute pancreatitis and its complications.

While the Revised Atlanta Classification outlines the primary complications of acute pancreatitis, it is crucial to recognize additional factors that contribute to morbidity and mortality associated with acute pancreatitis. In this review, we discuss the imaging-based classification and staging of acute pancreatitis as described by the Revised Atlanta Classification, but also provide a comprehensive understanding of the pancreatic anatomy and its relation to surrounding structures, which is essential for imaging-based assessment of both acute pancreatitis and its complications. We further extend the discussion beyond common complications such as pseudocysts and walled-off necrosis to include lesser-known but significant complications such as peripancreatic infection, disconnected ductal disconnection syndrome, thrombosis, hemorrhage, and gastrointestinal complications. Additionally, illustrative examples are presented to highlight relevant points pertaining to real-life imaging assessment of acute pancreatitis and its complications.

Malignant mesothelioma of the tunica vaginalis testis: A rare cause of hydrocele.

Mesotheliomas of the tunica vaginalis testis are very uncommon tumors, with rare cases published in the literature. This report demonstrates a case in with such a tumor was diagnosed in a 50-year-old man who presented to the emergency room with mild, acute scrotal pain and swelling, without previously known scrotal pathology. It is noted that sonographers should be aware of the typical characteristics that allow for suspecting malignancy in scrotal sonography performed in the emergency setting; this was particularly important in this case. Surgical pathology analysis of the right radical orchiectomy specimen confirmed the diagnosis.

Vaginal cancer: Why should we care? Anatomy, staging and in-depth imaging-based review of vaginal malignancies focusing on MRI and PET/CT.

Vaginal cancer often poses a challenge for clinical and radiological diagnosis, and its risk factors, progression, and treatment are still poorly established. Although vaginal malignancies are rare, even globally, their rates have increased due to the increased access to healthcare and the evolution of screening measures and diagnostic methods. Because the vaginal cavity is a virtual space, it can harbor lesions that often go unnoticed and, not infrequently, diagnosed belatedly. MRI and, more recently, PET/CT are part of the imaging armamentarium that have already been incorporated into the clinical staging and management of gynecological tumors, allowing excellent morphological characterization of the lesion, its topography and relationship with adjacent structures for the investigation of disease dissemination, overcoming limitations of clinical methods, such as speculum examination, usually restricted to observation only of the superficial characteristics of these lesions. Some vaginal neoplasms have characteristic MRI patterns, which, combined with expert knowledge of anatomy, allow identification of local macroscopic details (such as the mucosal, submucosal, and muscle layers). Furthermore, the application of PET/CT, already well established for identifying systemic disease, has a large impact on patient prognosis. The objective of this work is to review the epidemiological aspects of primary vaginal cancers and the imaging patterns of their main histological subtypes based on MRI and PET/CT, with a brief discussion of the local anatomy, oncological staging, and treatment.

Higher frequency of hepatic steatosis at CT among COVID-19-positive patients.

PURPOSE: Recent studies have demonstrated that obesity is significantly associated with increased disease severity, hospitalizations and mortality in COVID-19, with a potential role in the pathogenesis and prevalence in the new pandemic. The association with hepatic steatosis, however, a condition closely related to obesity within the spectrum of systemic metabolic dysfunctions, remains to be elucidated. We aimed to evaluate the frequency of hepatic steatosis as incidentally detected in chest CT examinations of COVID-19 positive patients in comparison to non-infected controls. METHODS: A retrospective study was performed with 316 patients (204 RT-PCR positive; 112 RT-PCR negative and chest CT negative). Steatosis was measured with placement of a single ROI in the right lobe of the liver (segments VI-VII) and defined as a liver attenuation value ≤ 40 HU. RESULTS: The frequency of hepatic steatosis was higher in the RT-PCR positive group in comparison to controls (31.9% vs. 7.1%, p < 0.001). Logistic linear regression analysis showed a 4.7 times odds of steatosis in the COVID-19 positive group as compared to controls after adjusting for age and sex (OR 4.698; 95% IC 2.12-10.41, p < 0.001). CONCLUSION: A significantly higher prevalence of steatosis was found among COVID-19 positive individuals. These findings are in accordance with other recent studies linking obesity and COVID-19 infection, as there is an intricate relationship between liver steatosis, metabolic syndrome and obesity. Further studies are required to confirm if such association remains after accounting for multiple variables, as well as possible relationships with disease severity and worst clinical outcomes.
