Diagnostic approach to small-bowel wall thickening: Beyond Crohn's disease and cancer.

Although small-bowel wall thickening is a common manifestation of Crohn's disease and tumors, many other entities can give rise to similar imaging findings. The small bowel is difficult to access by endoscopy, so radiologic imaging tests play an essential role in the diagnosis of conditions involving the small bowel. The main objectives of this paper are to explain the definition of small-bowel wall thickening, analyze the patterns of involvement seen in multidetector computed tomography (MDCT) with intravenous contrast administration, and provide an image-based review of the different causes of small-bowel wall thickening. The differential diagnosis must include many entities because wall thickening can result from immune-mediated, infectious, or vascular causes, as well as from toxicity and other lesser-known entities. As the imaging appearance of many of these conditions overlap, clinical and laboratory findings are necessary to support the imaging diagnosis.

A bibliometric study of the journal Radiología during the period 2010-2019. / Análisis bibliométrico de la revista Radiología en el periodo 2010-2019.

BACKGROUND AND AIMS: Bibliometrics makes it possible to measure the relative importance of a scientific journal in its field. The current study analyzed the scientific publications in Radiología and the bibliometric parameters of the journal in the period comprising 2010 through 2019. MATERIALS AND METHODS: We reviewed the bibliometrics for Radiología through information obtained from three sources: Scopus, the online version of the journal, and the publisher (Elsevier). We retrospectively analyzed aspects related to the editorial process (final decision and speed), the articles published (type, subspecialty of radiology, and imaging technique), the trends in citation and various indices (CiteScore, SNIP, and SJR), visibility, downloads, author characteristics (geographical origin and institutional collaboration), and the most cited articles. RESULTS: The number of articles published in Radiología gradually decreased during the decade, and the time to publication increased. Original research articles account for the largest share of the articles published. The most common subject areas were radiology of the digestive tract and neuroradiology. Nevertheless, the bibliometric indicators and the number of downloads of articles increased every year. Regarding the authorship of the articles published, although authors from Spain predominate, the participation of authors from other countries became increasingly common. Collaboration among different institutions also became increasingly common in the period analyzed. CONCLUSIONS: This review shows the progression of the journal's scientific work and some aspects that must be addressed to favor the growth of Radiología.

Ecografía de los cuerpos extraños subcutáneos: diferencias según naturaleza, complicaciones y potenciales errores diagnósticos / Ultrasonography of subcutaneous foreign bodies: differences depending on their nature, complications, and potential diagnostic errors

Los pacientes con heridas penetrantes y sospecha de cuerpos extraños retenidos representan un motivo frecuente de consulta en los servicios de urgencias. Es necesario un estudio radiográfico para descartar la presencia de cuerpos extraños. Sin embargo, las radiografías solo resultan de utilidad en los objetos radiopacos (metal, vidrio, piedra y algunos plásticos). Cuando la sospecha diagnóstica es alta y el estudio radiográfico es negativo, es necesario realizar otras pruebas de imagen. La ecografía ha demostrado su utilidad en la identificación y localización de cuerpos extraños tanto radiopacos como radiotransparentes. La ecografía permite una excelente evaluación de las estructuras adyacentes (músculos, tendones, ligamentos y estructuras neurovasculares) y ha demostrado ser de utilidad en la valoración de sus lesiones asociadas. Los diferentes materiales de los cuerpos extraños presentan patrones ecográficos característicos que resultan de utilidad para su aproximación diagnóstica. Por último, es importante estar familiarizado con los potenciales errores diagnósticos para evitar falsos positivos

Patients with penetrating wounds with suspected foreign bodies retained in the wound are often seen in emergency departments. Imaging studies are necessary to rule out the presence of retained foreign bodies. Plain-film X-rays, however, are only useful when the foreign bodies contain radiopaque material (metal, glass, stone, and some plastics). In cases with strong diagnostic suspicion and negative plain films, other imaging tests are necessary. Ultrasonography has proven useful in the identification and location of both radiopaque and radiotransparent foreign bodies. Ultrasonography enables excellent assessment of adjacent anatomical structures (muscles, tendons, ligaments, and neurovascular structures) and of associated lesions. The different materials found in foreign bodies have characteristic ultrasonographic patterns that are useful for diagnosis. Finally, it is important to be familiar with the diagnostic pitfalls to avoid false positives
