An initial investigation of serum cytokine levels in patients with gadolinium retention
Conclusion: The statistically significantly elevated cytokines may be markers of susceptibility to GDD or agents of symptom induction. These findings suggest that individuals developing symptoms characteristic of GDD after a contrast-assisted magnetic resonance imaging should be studied to investigate whether gadolinium retention and elevated cytokines may be related to their symptoms.Resumo Objetivo: Determinar se indiv íduos com doença de deposição de gadolínio (DDG) apresentam níveis séricos elevados de citocinas pró-inflamatórias e pró-fibróticas e se citocinas específicas estão correlacionadas com determ...

Percutaneous transhepatic approach to endoscopic placement of a 10F plastic biliary stent: step-by-step description of a novel technique
Abstract Intracranial calcifications, which are common in the daily routine of radiologists, can have a physiological or pathological origin. Determining the cause of intracranial calcifications can represent a challenge. The anatomical location, distribution, dimensions and morphology of such calcifications are important findings, which, in conjunction with the clinical history and age group, can facilitate the differential diagnosis. The aim of this pictorial essay is to demonstrate the different types of intracranial calcifications and their origins. The images evaluated were those stored in picture archiving and commun...

Non-neoplastic cholangiopathies: an algorithmic approach
Abstract Cholangiopathies are chronic diseases that affect the bile ducts, comprising a heterogeneous group of progressive and potentially fatal entities. The diagnosis of these diseases is a great challenge for radiologists because of the overlapping of their clinical, biochemical, and imaging findings. Nevertheless, identifying the precise etiology is crucial, given that the therapeutic options are distinct and influence the prognosis of the patient. The purpose of this review article is to discuss some of the non-neoplastic causes of cholangiopathies and to provide a useful diagnostic algorithm.Resumo As colangiopatias ...
