Usefulness of dynamic contrast-enhanced MRI in the evaluation of osteonecrosis of the proximal fragment in scaphoid fractures
Abstract Although the primary purpose of periodic mammograms in screening programs is to identify lesions suspected of being carcinomas, the findings are often related to systemic (benign or malignant) diseases, rather than breast cancer. Although the involvement of breast structures in systemic diseases is unusual, it can be included in the differential diagnosis of masses, skin changes, calcifications, asymmetry, and axillary lymphadenopathy. The main diagnostic entities that can be associated with such involvement are diabetes, chronic kidney disease, heart diseases, connective tissue diseases, HIV infection, lymphoma, ...

Idiopathic interstitial pneumonias: review of the latest American Thoracic Society/European Respiratory Society classification
In this study, we review the main clinical, tomographic, and pathological characteristics of each IIP.Resumo O diagn óstico das pneumonias intersticiais idiopáticas (PIIs) envolve um cenário multidisciplinar no qual o radiologista assume papel fundamental. A última atualização (2013) da classificação das PIIs pela American Thoracic Society/European Respiratory Society propõe algumas mudanças importantes em relação à classificação original de 2002. Dentre as novidades, destacam-se o acréscimo de uma nova doença (fibroelastose pleuroparenquimatosa idiopática) e a subdivisão das PIIs em quatro grupos princi...

Tomographic assessment of thoracic fungal diseases: a pattern and signs approach
Abstract Pulmonary fungal infections, which can be opportunistic or endemic, lead to considerable morbidity and mortality. Such infections have multiple clinical presentations and imaging patterns, overlapping with those of various other diseases, complicating the diagnostic approach. Given the immensity of Brazil, knowledge of the epidemiological context of pulmonary fungal infections in the various regions of the country is paramount when considering their differential diagnoses. In addition, defining the patient immunological status will facilitate the identification of opportunistic infections, such as those occurring ...

Radiology report: what is the opinion of the referring physician?
Conclusion: Referring physicians seek detailed reports (including a description of the examination technique), preferably structured, with objective language and relevant conclusions (the position of the radiologist on the case is important). It is necessary to discuss the differential diagnoses and provide a form of contact between the parties. Although referring physicians consider the radiologist opinion relevant, they also want to analyze the images on their own.Resumo Objetivo: Avaliar a opini ão e a percepção dos médicos solicitantes sobre o laudo radiológico e desenvolver ferramentas que promovam uma melhora d...

The role of a novel magnetic resonance imaging sequence in the evaluation of the fetal skeleton: a pilot study
Conclusion: A detailed evaluation of the three-dimensional reconstructions of fetal skeleton performed after acquisition of a modified VIBE MRI sequence allowed a full characterization of the skeleton. However, improvements to the proposed sequence should be addressed in future studies.Resumo Objetivo: O objetivo deste estudo foi demonstrar o papel da resson ância magnética (RM) incluindo uma nova sequência chamada de volumetric interpolated breath-hold examination (VIBE)) modificada que permita a reconstrução tridimensional para avaliação do esqueleto fetal. Materiais e Métodos: Foram analisadas 22 mulheres grá...

Ultrasound as a method to evaluate the distribution of abdominal fat in obese prepubertal children and the relationship between abdominal fat and metabolic alterations
Conclusion: In obese prepubertal children, the AWT, as measured by ultrasound, was shown to be more closely related to the HOMA-IR than to the lipid metabolism or glycemia.Resumo Objetivo: Avaliar, em crian ças pré-púberes obesas, a distribuição da gordura no abdome por meio da ultrassonografia e sua possível correlação com as alterações metabólicas decorrentes da obesidade. Materiais e Métodos: Estudo transversal em crianças pré-púberes, sendo 77 obesas (33 meninas e 44 meninos) com mé dia de idade de 7,31 anos e 31 eutróficas (17 meninas e 14 meninos) com média de idade de 7,32 anos. Em todas as crian...

Epidemiological and imaging features that can affect the detection of ureterolithiasis on ultrasound
Conclusion: A high body mass index, large calculus diameter, and calculus location in the distal third of the ureter are the major factors favoring ureterolithiasis detection on ultrasound.Resumo Objetivo: Identificar achados epidemiol ógicos e de imagem em pacientes com suspeita clínica de ureterolitíase que afetam a detecção do cálculo no ultrassom (US), comparado com a tomografia computadorizada multidetectores (TCMD). Materiais e Métodos: Procuramos, em nosso banco de dados, por pacientes que realizaram US no serviço de emergência, seguido por TCMD (se US negativo), por suspeita de ureterolitíase. Os pacien...

Radiation-induced angiosarcoma of the breast: a retrospective analysis of 15 years' experience at an oncology center
Conclusion: RIAS of the breast is a rare but recognized complication of radiotherapy for breast carcinoma, with a poor prognosis and high recurrence rate, which requires a high index of suspicion for a prompt diagnosis.Resumo Objetivo: Caracterizar uma popula ção de pacientes com angiossarcoma da mama induzido por radioterapia em um instituto de oncologia, com foco principalmente nas características de imagem, mas também na apresentação clínica, diagnóstico e gerenciamento. Materiais e Métodos: Efetuamos análise retrospectiva, entre 2000 e 201 5, de pacientes com angiossarcoma da mama ou parede torácica histol...

Stress fracture and osteomyelitis in a patient with systemic lupus erythematosus
Abstract The rheumatic diseases, which include systemic lupus erythematosus, rheumatoid arthritis, Beh çet's disease, scleroderma, and ankylosing spondylitis, are characterized by involvement of connective tissue, with multiple manifestations. In those diseases, there can be involvement of the peripheral or central nervous system, and that involvement can be primary, presenting as a major feature of the clinical presentation, or secondary, as an effect of the drugs used in order to control a given disease or its complications. Knowledge of the wide variety of imaging findings is crucial to the diagnosis of a rheumatic di...
