Diffusion-weighted imaging and apparent diffusion coefficient values for evaluating terminal ileitis in patients with Crohn’s disease
Conclusion: Visual analysis of the DWI sequence has good accuracy in detecting terminal ileitis in patients with Crohn ’ s disease. In addition, low ADC values have good sensitivity for detecting colonoscopy-proven inflammation.Resumo Objetivo: Determinar a acur ácia da ressonância magnética com difusão na identificação de sinais de inflamação ileal distal em pacientes com doença de Crohn. Materiais e Métodos: Estudo retrospectivo com 38 pacientes consecutivos com doença de Crohn que foram submetidos a enterografia por ressonância magnética. O s pacientes foram alocados em duas categorias, utilizando a pos...

Computed tomography-measured body composition: correlation with postoperative morbidity and mortality in patients with gastroesophageal cancer
Conclusion: Our data suggest that lean body mass can be a relevant prognostic factor in patients with gastric or esophageal cancer, and that CT measurements should be included in the routine preoperative evaluation, because it may provide information that aids nutritional and clinical care for these patients.Resumo Objetivo: Investigar se medidas antropom étricas e tomografia computadorizada (TC) da composição corporal podem predizer morbimortalidade pós-operatória em pacientes com câncer gástrico e/ou esofágico. Materiais e Métodos: Estudo retrospectivo que revisou prontuários médicos e TCs abdominais de paci...

Relationship between right atrium area and right ventricular ejection fraction on magnetic resonance imaging: comparison with other prognostic markers in patients with pulmonary arterial hypertension
Conclusion: In patients with PAH, cardiac MRI-derived RVEF appears to correlate more strongly with other prognostic factors than does RA area.Resumo Objetivo: Comparar a área do átrio direito (AD) e a fração de ejeção do ventrÃculo direito (FEVD) com outros marcadores prognósticos conhecidos em pacientes com hipertensão arterial pulmonar (HAP). Materiais e Métodos: Identificamos, retrospectivamente, 74 pacientes com diagnóstico de HAP por cateterismo car dÃaco direito em um centro de referência, no perÃodo de 3 meses da ressonância magnética cardÃaca (RMC), entre janeiro de 2018 e maio de 2018, que tambÃ...

Prevalence of additional primary malignancies detected incidentally on PET/CT
Abstract Endometriosis is characterized by the presence of endometrial tissue outside the uterus. When endometrial implants penetrate more than 5 mm into the peritoneum, the condition is referred to as deep pelvic endometriosis. Although laparoscopy is the gold standard test to establish a diagnosis of deep endometriosis, transvaginal ultrasound represents an alternative that can contribute to detection of the disease, because it is an accessible, low-cost, noninvasive examination that allows preoperative planning in cases requiring surgical treatment. However, in clinical practice, transvaginal ultrasound is still not wid...

What the radiologist should know about the role of interventional radiology in urology
Abstract Interventional radiology has been constantly developing in terms of the techniques, materials, and methods of intervention. It interacts with all areas of medicine, always with the ultimate goal of ensuring the well-being of patients. Advances in imaging techniques, especially in the last two decades, have led to a paradigm shift in the field of urological imaging interventions. Many urologic diseases that were previously treated only surgically can now be effectively managed using minimally invasive image-guided techniques, often with shorter hospital stays and requiring only local anesthesia or conscious sedatio...

The many faces of primary and secondary hepatic lymphoma: imaging manifestations and diagnostic approach
Abstract Hepatic lymphoma can be divided into its primary and secondary forms. To be classified as primary hepatic lymphoma, the disease should be limited to the liver and hilar lymph nodes, with no distant involvement (to the bone marrow or other sites). Primary hepatic lymphoma is quite rare, accounting for less than 1% of all cases of non-Hodgkin lymphoma, whereas secondary hepatic lymphoma affects nearly half of such cases. Familiarity with the imaging features of hepatic lymphoma is important for its early diagnosis and appropriate management. In this essay, we aim to review the roles of computed tomography and magnet...
